    - Output sequence for WPP software tracing Moin, I use WPP software tracing in my driver. For each trace line the first item shown is the CPU number in brackets. I'm wondering if there is a output sequence for those trace messages for the same time stamp. I'm currently analyzing a problem within my driver. The driver has a queue of messages with numbers in sequence. For any reason I see the messages fetched in a different order: [3]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89528008 READ cmd=0x82ff nr=0x4fcf [3]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89528008 READ cmd=0x82ff nr=0x4fd1 [1]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89337E68 READ cmd=0x82ff nr=0x4fce [2]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=8987D8F8 READ cmd=0x82ff nr=0x4fd0 I would expect the following order: [1]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89337E68 READ cmd=0x82ff nr=0x4fce [3]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89528008 READ cmd=0x82ff nr=0x4fcf [2]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=8987D8F8 READ cmd=0x82ff nr=0x4fd0 [3]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89528008 READ cmd=0x82ff nr=0x4fd1 Is it simply a sequence issue caused by WPP ?

    - NdisRegisterDeviceEx() and CreateFile() security settings. Hi all Ndis 6 and Vista... I am using NdisRegisterDeviceEx() with as SDDL of "D:P(A;;GA;;;SY) (A;;GA;;;BA)(A;;GRGW;;;BU)(A;;GRGW;;;WD)" and it returns STATUS_SUCCESS. With a symboliclinks viewer I can see my device. But, when I try to open it with CreateFile() is using GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL I get the error: 'The request is not supported'. I have tried it with a 0 SDDL too with the same result. I am logged in as Administrator but this needs to work for users too. The old function, NdisRegisterDevice() works on Vista with my Ndis 5.1 driver. Doeas anyone have any ideas? I looked at the netvmini code that ships with the 6000 DDK and dont seed any reason for my code to fail. Thanks in advance for any suggestions on this.

    - Vista 64 bit: HowTo receive origin inf file location? Hi! I need to receive the origin inf file location (path) through my CoInstaller dll when installing a hardware device. I´ve done that in the past using SetupDiGetSelectedDriver and SetupDiGetDriverInfoDetail. Doing it the same way on Vista 64 bit the path points to \Windows\inf. But I need the origin path. Is that somehow possible? Thanks, Nick Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91315

    - hInstance field in PROPSHEETPAGE structure: MSDN doc not correct ( This is maybe not the right place to post this, but I lost almost a whole week because of it, so I hope it will be helpful to someone: The "hInstance" filed in the PROPSHEETPAGE structure must not only be set when you use the "pszIcon, pszTitle, pszHeaderTitle, or pszHeaderSubTitle members" like specified in the MSDN (see below) but also when you specify a resource template in the pszTemplate member (the WIndows CE documentation is apparently correct) Win32 docu: (http://msdn2.microsoft.com/en-us/library/ms652419.aspx) hInstance: Handle to the instance from which to load an icon or string resource. If the pszIcon, pszTitle, pszHeaderTitle, or pszHeaderSubTitle member identifies a resource to load, hInstance must be specified. Windows CE docu: (http://msdn2.microsoft.com/zh-CN/library/aa453562.aspx) hInstance: Handle to the instance from which to load the dialog box template, icon, or title string resource.

    - UpdateDriverForPlugAndPlayDevices fails - Please HELP Hi, I want to install a driver for non-PnP printer. For this I create and register a devnode for my device. Then I try to call UpdateDriverForPlugAndPlayDevices to update the drivers for the PnP devices. I expected to see my printer added but the UpdateDriverForPlugAndPlayDevices failed instead. The driver was installed but the printer was not on the "Printer and Faxes" page. If I add manually "PortName" and its value under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\Printer\0000\Device Parameters" and then call UpdateDriverForPlugAndPlayDevices I have the printer installed. The problem is that the "Device Parameters" key appears after calling UpdateDriverForPlugAndPlayDevices. I cannot create the "Device Parameters" key manually because I am not allowed to. There should be a way to add the PortName parameter somewhere/somehow so that the printer installation to succeed. Are there another settings that I should add in order to get the printer installed correctly? Thanks a lot Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91284

    - Intel ICH8 chipset doesn't response a DMA ack....(Vista) Folks: I was porting my FIR driver to Vista. My FIR driver work fine on my SIS EV board (both XP and Vista). My Custom used INTEL ICH8 chipset (for mobile). XP worked fine but Vista didn't work. During FIR negotiation, each computer will send/receive 2 bytes data (command and address) and 4 bytes FCS check code. Normally, FIR will send/receive a 6 bytes data (2 bytes data and 4 bytes command). I used LA to monitor DMA cycle and found out Vista didn't response the 5th time DMA ack. The FIR negotiation failed. Then repeated the error. Anyone knew how to monitor DMA operation ? I mean once I start DMA transfer. DMA should move data automatically. How did I know which steps DMA operation was wrong ? There is a strange situation: I installed XP and Vista in the same HD. There is two OS I could choose during booting. If I entered XP then reboot, changed to Vista (without unplug power). My FIR worked fine. If I removed my power core then plug, booting in Vista. The FIR driver failed to connect. Anyone can give me an advice ?

    - HID mouse, digitizer device/driver Hi to kernel gurus! I have custom HW (non HID) connected to PC via USB + software system which calculates Tablet PC- like stylus position. The goal is to provide valid mouse and digitizer input form kernel mode. As far as I understand I have to provide valid HID reports to OS. I have to create HID minidriver which does not have any real HW behind , but receives coordinates form NT service. 1) Is HID minidriver an appropriate solution ? 2) In case I would like to provide mouse input will I be able to communicate with my driver form my software ? I understand that OS exclusively locks mouse driver stack. 3) Should I implement separate driver for mouse and digitizer? 4) Can anybody give a reference to the useful driver sample? 5) What is the best way to communicate between my HID driver and my software? (HID reports, CreateFile() , Pipes, Section) Thank you in advance, David. Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91269

    - SetupUninstallOEMInf() FAILS on Vista x86 We have a custom installation utility for a USB device that performs the following actions on Vista x86 : 1/ Installs the .INF and driver using SetupCopyOEMInf(). 2/ Removes the device using SetupDiSetClassInstallParams(DIF_REMOVE) 3/ Removes the corresponsing oem??.inf and oem??.pnf for the device Questions : 1/ We want the installation utility to remove the files in the DriverStore\FileRepository directory as well so we are using SetupUninstallOEMInf(SUOI_FORCEDELETE). This call fails with error code 0x57 (The parameter is incorrect. ) How can we fix this ? 2/ Inspite of the fact that the files in DriverStore\FileRepository are not being deleted, when Vista reenumerates the device, it does not find the .INF file for installing the driver. The driver is not signed. Doesn't the OS look for drivers in DriverStore\FileRepository ? Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91268

    - Help! Print Processor Clipping Path Help! I am writing a generic print processor to draw text to the bottom of every print job, like a watermark. On some drivers, the clipping path is set to enclose the original document text, and exclude the rest of the pate. For example, if I draw text in the print processor in the center of the page, but there is only one line of text in at the top of the page of the original document, the text drawn in the print processor will be clipped. I have tried to expand the clipping path, trying almost every clipping function, including removing it altogether. However, I can not change the bottom dimension of the clipping rectangle, no matter what I do. I can change every other dimension of the rectangle, though. Is there something I can do to change the clipping path in a print processor? Modifying the driver is really not a good option, and this is supposed to work for any driver.

    - DIFx Issue for Composite USB Devices We have a composite USB device. It has 2 interfaces each belonging to a different setup class and is driven by a single driver. Following are some details about the devices. INTERFACE #1 : HardwareId=USB\VID_vvvv&PID_pppp&MI_00 SetupClass=Modem .INF File=x.inf FunctionDriver=modem.sys (inbox) LowerFilterDriver=mydriver.sys (installed by .INF file) AddService Line in .INF as as follows : AddService= mydriver, 0x00000000, Device.AddService [Device.AddService] DisplayName=%SERVICENAME% ServiceType= 1 StartType = 3 ErrorControl = 0 ServiceBinary = %12%\mydriver.sys INTERFACE #2 : HardwareId=USB\VID_vvvv&PID_pppp&MI_01 SetupClass=Port .INF File=y.inf FunctionDriver=mydriver.sys (installed by .INF file) AddService Line in .INF as as follows : AddService=mydriver, 0x00000002, Device.AddService [Device.AddService] DisplayName=%SERVICENAME% ServiceType= 1 StartType = 3 ErrorControl = 0 ServiceBinary = %12%\mydriver.sys PROBLEM: We are using DifXCmd.exe sample from the WDK to install and remove the drivers and the device itself and we are having the following issue. Installation for both these interfaces devices go through fine. However when we attempt to remove the devices DIFxCmd always fails for the interface #1. We have tried quite a few things but nothing seems to work. >From the setupdi.dev.log the failure seems to be in a function in setupdi.dll SetupDiGetSelectedDriver() which fails with the error code ERROR_NO_DRIVER_SELECTED for INTERFACE (E0000203) #1. Is this a bug in PnP Manager or DifX APIs that manifests itself when uninstalling drivers for composite USB devices? Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91261

    - Anyone run DTM on a digital tuner yet? I have a USB digital TV tuner device and BDA driver - HCT-tested (on XP) without problem. I have applied the following dimensions to the machine pool: Ehome\HasTvTuner, Wdk\ConfigureBroadcastReceiverStreaming, Wdk\ConfigureVideoCaptureStreamingMedia. I go to the Device Console, select View By Machine, and then select my device in the Available Devices tree. The Available Jobs pane then shows me the Driver Reliability and Generic categories, but no TV Tuner category. If I View By Driver then the TV Tuner category shows when I select the "MEDIA Driver (Service Name <name>)" level, but again when I select the actual device (one level down), the TV Tuner tests disappear. Anyone mananged to get these tests run on a digital tuner? (Some are certainly analogue only, in fact, but many - according to DTM's own help file - do apply to digital too) Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91255

    - NdisMAllocateNetBufferSGList keeps failing. Hi, When I do large ftp xfers, I receive a huge request from NDIS (which it received from app). NdisMallocateNetBufferSGList consistently fails and the ftp connection ends up getting aborted. Questions: 1. How do I analyze the failures from NdisMallocateNetBufferSGList ().. The error return is NDIS_STATUS_RESOURCES. This does not change irrespective of whether I provide buffer to store the SGLIST or not.. 2. How do I find whether there are any real memory issues? 3. What reasons can the above call fail? Is it lack of kernel memory? Is it due to lack of non-paged pool memory? Thanks for your answers. -Praveen Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91248

    - NdisMIndicateReceivePacket for large packets Hi all, Is it legal for an NDIS miniport to indicate up packets larger than what it specified as the maximum via various OIDs (such as OID_GEN_MAXIMUM_FRAME_SIZE, OID_GEN_TRANSMIT_BLOCK_SIZE, OID_GEN_RECEIVE_BLOCK_SIZE, OID_GEN_MAXIMUM_TOTAL_SIZE)? In other words, if the default configuration of the device is to have a maximum packet size of 1514 bytes (to prevent issues arising with applications sending jumbo frames on a non-capable network) but the hardware is always capable of receiving larger packets if they happen to be on the wire, should these be filtered out by software because they happen to be larger the the maximum size returned via the above OIDs? The driver in question is a deserialized miniport with NDIS_MAC_OPTION_TRANSFERS_NOT_PEND set, so we always indicate full packets up to the stack. I've tested indicating up larger packets than we tell NDIS we support, and everything seemed to still handle them fine (tested via TDI and Winsock), but I am concerned that some intermediate driver could possibly get confused if it gets packets larger than what it thought we would indicate up. In essence, is there a proper way to indicate to NDIS that we do not want to support transmitting packets larger than the default frame size of 1514-bytes but yet still indicate up packets larger than this on the receive side? Thanks, EricG Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91240

    - USB IRP sometimes hangs with hyper-threading enabled Hi, I'm trying to track down an intermittent hang in my application/driver. Using the kernel debugger I've narrowed it down to an IRP being sent down the driver stack and getting stuck. Admittedly I've only seen it on one machine so far.

    - Setting metric for an NIC Hi Experts: On my Windows XP, I tried to the metric for one of the network cards through the TCP/IP settings, say set it to 10, it seems took effect as shown by the output of "route print"; but after a short while, it goes back to its original automatically configured metric of 20 as shown in "route print". Why is this, is the manual setting supposed to be perminent? Thanks in advance Polaris Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91230

    - A corker on x64 checked builds only For some bizarre reason, the build process for x64 on Winddk 5600, using the server 2003 x64 checked build environment (and only that one) blows away anything named tmp, including folders. x64 free, x32 checked and free don't do this. In any case, we use Subversion for our version control - which puts tmp folders in a hidden .svn folder under {driver base folder}\objfre_wnet_amd64 So the folder structure is {driver base folder}\objfre_wnet_amd64 .svn\ prop-base\ props\ text-base\ wcprops\ tmp\ prop-base\ props\ text-base\ wcprops\ Simply doing a "build -ceZ" will recursively blow away all the tmp folders it finds under objfre_wnet_amd64, whether it owns them or not. Is there a way to get this to stop doing this? It's totally screwing up my version control system. G Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91227

    - How to retreive the inf file path in a device manager property pag Dear All, I'm still trying to retreive the inf file path used to install the current device, in my device manager property page (see my previous post about that). I'm using the device info set and device info data provided by the OS in the property page provider entry point. My question is: WHY IS THERE NO SELECTED **DRIVER** (the SetupDiGetSelectedDriver says ERROR_NO_SELECTED_DRIVER)? Note 1: I can enumerate the compatible drivers for that device (SetupDiBuilDriverInfoList( SPDIT_COMPATDRIVER ) + SetupDiEnumDriverInfo) but I don't know how to "link" one of them with my current device. Any hint about that? Note 2: I have also implemented a co installer and with the device info set and device info data provided in the co installer entry point I can get the current selected driver. Many thanks in advance, Have a nice day all, Francois. Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91212

    - Printer Driver Migration - XP to Vista Hi, We had developed printer drivers few years back that works well on Win-2K and Win-XP. now we want to migrate it to Windows-Vista. What all we need to do. I have investigated about it by reading WDK documentation and some articles on internet but now I am confused. At link https://ms.helifan.net/whdc/DevTools/WDK/Win2k_install.mspx, its written that "In conformance with Microsoft support policy, Microsoft is removing Windows 2000 from its list of supported installation platforms for the Windows Driver Kit (WDK). The WDK continues to provide a Windows 2000 build environment for the development of drivers targeting Windows 2000." and at link http://www.microsoft.com/whdc/devtools/ddk/default.mspx, its written under "When to Use the Windows Driver Kit (WDK)" that - "Use the Windows 2000 build environments in the WDK to build drivers designed to run on Windows Vista, Windows Server 2003, Windows XP, or Windows 2000. The Windows 2000 build environment in the WDK includes updated headers and libraries for Windows 2000 Service Pack 4 (SP4)." I have few queries - 1. Please tell me which WDK build environment should we use to build the driver that is targetted to run on Windows-Vista. Also please tell us which source code should we take as a base, Win-2K or Win-XP 2. What all things need to be installed to build the source code properly. The existing Win-XP source code requires Windows Server 2003 DDK, MS Platform SDK-Feb 2003, Visual C++ 6.0 [SP5] to build it properly. 3. We have installed the WDK and tried to build the existing Win-2K source code with W2K build environment, but we are getting the following errors - ********************************************************************************************* errors in directory c:\printerdriver\printerinterface c:\winddk\6000\bin\makefile.new(803) : error U1080: operator and/or operand usage illegal nmake.exe /nologo BUILDMSG=Stop. -i BUILD_PASS=PASS1 NOLINK=1 MAKEDIR_RELATIVE_TO_BASEDIR= MAKEDIR_LOWERCASE=c:\printerdriver\printerinterface failed - rc = 2 BUILD: Compile errors: not linking c:\printerdriver\printerinterface directory BUILD: Finish time: Wed Jan 24 13:00:02 2007 BUILD: Done 0 files compiled - 2 Errors ********************************************************************************************* These errors are coming in different modules also. The errors pasted above is only for one module. 4. Do we have to set the VC environment variables each time we open the WDK build environment. Because otherwise it give errors like [could not find string.h]. This file is located in WinDDK\6000\inc\crt folder but this folder is not searched for the header files. 5. Is it possible to have a single version of Printer Driver that works for all Windows versions [2000, xp and vista]. 6. There is a Compatibility mode in Windows-Vista. We have installation setup for our printer driver. I ran the installation setup using the compatibility mode and it ran successfully. The installation utility adds the port monitor and print processor and copies all other driver files in a folder. After this we need to install the printer driver using the add printer wizard. But when I try to install the printer driver using add printer wizard, it gives error saying that "Printer driver was not installed. Operation could not be completed (error 0x0000007e)." Can anybody please give me some hints what could be the issues. Anybody from Microsoft??? I tried to send the mail to wdkfb@microsoft.com but it bounced back. Does anybody know the correct mail address where I can send these queries to microsoft people. Thanks, Nitin Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91204

    - ENUM\USB\xxx entry missing I have a USB device based on a Cypress EZ-USB chip. When it's plugged in, a driver loads, downloads firmware to the device, and disconnects. The firmware then runs and the device reappears on the bus under a different PID. This time in-box HIDdrivers are loaded and we're off to the races. After this is all over, there is an entry for the device under ENUM that looks like this: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USB\VID_xxxxE&PID_yyyy&MI_00\blahblahblah I believe "blahblahblah" contains information for the system to find the driver the next time the device is plugged in. On four identical Dell Optiplex systems, the device works when plugged in, but not when unplugged and replugged. When I look at the registry, HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USB\VID_xxxxE&PID_yyyy&MI_00 is there, but "blahblahblah" has disappeared. This of course causes the Found New Hardware Wizard to open again. Has anyone seen this kind of issue? Thanks. Fred Petaluma, CA.

    - MI5 Persecution: Surveillance methods 5/8/95 (5958) From: Pamela Willoughby <pjw31@willouby.demon.co.uk> Newsgroups: uk.misc Date: Sat, 05 Aug 1995 18:08:32 GMT Organization: Myorganisation Lines: 15 Message-ID: <142297143wnr@willouby.demon.co.uk> >Hmmm, strange eh. >I mentioned all this goings on to my boyfriend, who works for the >British intelligence service, and he assures me this sort of thing >never goes on.. not ever...honest. >Though he said the name was familiar... it does go on, although it's an open question who does it. Some time ago there were press reports of an Army intelligence person called Jones who claimed Diana and Hewitt had been photographed in a compromising position... he said he'd been doing this as part of an Army unit which had previously operated in Northern Ireland. Then Hewitt said he'd been told the same thing by some Army people, and that they were threatening to release the tapes unless they curtailed their liaison... as per usual everyone denied everything, painted Jones as the "Jones twins" - not very original in how they deal with their perceived enemies, are they? You have to wonder how they manage to achieve this sort of surveillance though. Audio you can understand, it's possible to put a microphone through the wall, and apparently there exist devices which will retrieve sound from a laser beam bounced off a window - sounds sci-fi, but there's a well known surveillance electronics company in London which sells these things. But how would you get video out of a room, unless you had actual physical access in order to plant a device for pickup? We're not talking about looking in from afar, but an actual device within the room. You could either drill through the wall and shove a pickup through; or you could supply a trojan device with a hidden pickup inside; but most likely, you would have to physically break into your target room to plant a camera. That's not an infeasible option; all it means is having your target(s) watched to make sure they're not in the vicinity, then you negotiate any locks on the property and find a suitable receptacle for your device. The next question is how they defeat the usual methods of counter- surveillance. We had private detectives carry out a "sweep" of every room and the telephone line. They found nothing. That indicates at least four possibilities that I can think of; (this is all guesswork BTW, and probably fanciful guesswork at that!) 1) no bugs (pull the other one) 2) radio-transmitting devices which can be controlled from an external source, ie you can instruct them to switch off when you detect a counter-surveillance sweep taking place 3) hard-wired devices; probe microphones or whatever they're called, things you poke through the wall 4) passive surveillance devices; so you bounce laser or radio waves off a suitable reflecting surface (again, sounds far-fetched but such things may apparently exist). 5) there is a fifth possibility, that the PI's didn't detect an actual transmitting device; there are technologies specifically designed to avoid detection, eg frequency hopping and suchlike. But how much sophistication could you build in to a device which would have to be small enough to be physically concealable? I guess the real question is to find out who is ultimately behind these "goings on". And if the "great and good" (or the better known, at any rate) can't protect themselves, what hope is there for the rest of us? 5958 -- Posted via a free Usenet account from http://www.teranews.com Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91188

    - XP vs Vista behavior change with USB surprise device removal Howdy everyone, I have noticed a slight change in behavior when doing surprise removal of a USB device on Vista, as compared to XP. On XP, when our USB HW has been physically removed but the device driver has not finished acknowledging the removal(i.e we are still handling the IRP_MN_SURPRISE_REMOVAL), the USB stack will automatically complete new IRPs targeted for the now defunct device with an error. That is, IoCallDriver returns STATUS_NO_SUCH_DEVICE, and the IRP is completed with the same status. The behavior is the same whether the device is directly unplugged, or the external hub that the device is plugged into is unplugged. So far so good. On Vista, the behavior is the same in most cases, except in the case where the HW is physically removed by unplugging the hub from the computer, rather than unplugging the device from the hub. In the hub removal case, the USB stack seems to accept the IRPs, but might never complete them. IoCallDriver returns STATUS_SUCCESS, but the IRP is not completed until explicitly cancelled by our driver. I realize that our driver probably shouldn't depend on the lower drivers automatically rejecting those IRPs, but I'm wondering if this change in behavior is expected? It seems strange that it only behaves this way when the hub is unplugged, and not when the device is unplugged directly, especially considering both cases had the same behavior in XP. Does anyone else find this strange? Or can anyone explain why it changed? Thanks! -phil Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91187

    - CPUID in Kernel Giving Unexpected Result I'm struggling to implement Intel VMX functionality via a driver. Part of my VMX set-up is to first determine that the processor supports VMX (CPUID.EAX[01h] -> ECX[bit 5 = 1]. If I run the following code in user space on my Core 2 Duo Extreme I get the correct information (VMX supported). Running the same code in kernel space indicates the machine does not support VMX. Fyi, I linked the asm code into driver via asm generated .obj file. Also, I'm testing both user mode and kernel mode in VMWare. ///////////////////////////////////////////////////////////// mov ax,01h cpuid and cl,20h ; mask test of bit 5 in EAX - result of 1 indicates VMX jnz VMX_Supported jmp VMX_Not_Supported ////////////////////////////////////////////////////////////// I ran this code in debuggers and in fact cpuid gave different results in ECX between user mode and kernel mode.

    - Residual registry entries and files after uninstall After uninstalling a USB device driver package, binaries, and all related devices using DIFxApp and DIF_REMOVE SetupDiCallClassInstaller(), I have found that I still have a number of registry entries and files related to the drivers on disk. I initially assumed they were harmless, but recently, one of our testers had a series of BSODs that were completely resolved by manually removing all of the residual files and registry entries. Our conclusion is that somehow, an older version of one of the drivers was being loaded and interacting badly with the others. What I don't know is which, if any, of the removed objects was responsible for the problem. Here is the list of objects that were removed, after which the problem appeared to be fixed: Registry keys: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Reinstall\XXXX keys containing references to our devices SYSTEM\ControlSetXXX\Control\Class\<class GUID>\XXXX keys containing references to our devices HKLM\SYSTEM\ControlSetXXX\Enum\USB\<our device> HKLM\SYSTEM\ControlSetXXX\Services\<services installed with our devices> Files: \WINDOWS\inf\oemxx.inf -- copies of our .inf Can anyone tell me which, if any, of these keys and files could lead to an incorrect driver package component being loaded for a PnP device? Are any of these worth worrying about and pursuing a way to clean up? Does Microsoft provide any API or automatable tool for cleaning these up?

If I run my app for 15 times the system is crashed for atleast 5 times giving any of the above errors. I suspect that these errors deal with paged code concepts. My questions are can a paged code call a non paged code.Is it a strict rule to be applied. can my code which waits using kewaitforsingleobject( ) be in paged code.Documentation says "In addition, remember that driver code must not be marked as pageable if it calls any KeXxx support routines, such as KeReleaseMutex or KeReleaseSemaphore, in which the Wait parameter is set to TRUE. Such a call returns with IRQL at DISPATCH_LEVEL and the dispatcher database locked" Is it for all Kexxx commands or only these two. If it is for all kexxx commands then most of the place we will be waiting using kewaitforsingleobject( ) fn (ie after sending urb to the lower driver).Then it may lead to put most of the code in non paged area. can anyone clear my doubts.How can I judge which to put in nonpaged and which to put in paged code thanks in advance.

    - Recommended method to set multicast MAC addresses in netvmini Hello, I'm trying to set the multicast addresses (MAC, not IP) in the netvmini sample using a user-mode application. I'm also trying to avoid using any winsock functions to accomplish this. The method I chose was to send an OID_802_3_MULTICAST_LIST, using the ndisprot sample's ndisprotSetOidValue() function, to the netvmini instance. However, this appears to append the MAC address to the Adapter->arrMCList of every netvmini instance, instead of just the chosen instance. Why does this occur? Is there a better way to do this (set multicast addresses) without resorting to winsock functions? Any help would be greatly appreciated. Note: I used the uiotest app included in the ndisprot sample as a guide: 1. Open ndisprot handle 2. Open specific ndis device using IOCTL_NDISPROT_OPEN_DEVICE 3. Send IOCTL_NDISPROT_SET_OID_VALUE to ndisprot, with the NDISPROT_SET_OID structure containing OID_802_3_MULTICAST_LIST and the MAC address 4. Close the ndisprot handle Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91136

    - Power Management in a Miniport Driver with a WDM Lower Interface Hi, I have a question regarding Power Management in a Miniport Driver with a WDM Lower Interface. According to a documentation "The miniport driver must always return NDIS_STATUS_SUCCESS to an OID_PNP_SET_POWER request". However, in the ndiswdm example they return NDIS_STATUS_PENDING and forward this request to the lower binding. My questions are: 1. Can I answer OID_PNP_SET_POWER with NDIS_STATUS_PENDING? I would like to use this mechanism to communicate with a device before entering D3. 2. If Yes, should I forward OID_PNP_SET_POWER to the lower binding or NDIS will do it for me? As far as I understand, if I return NDIS_STATUS_SUCCESS, NDIS will do it for me. Thanks in advance, Igor. Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91135

    - WORKER_THREAD_RETURNED _AT_BAD_IRQL in TDI.sys Hi All, WORKER_THREAD_RETURNED _AT_BAD_IRQL Caused by: TDI.sys I face this bugcheck after a few seconds after the ethernet cable is unplugged while my driver, which is a TDI client, is doing some data transfer. My driver uses the TDI for TCP type of connection. Can you please let me know why this error is being caused? Please let me know if need to post any extra information. Thanks in advance, Pavan Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91133

    - Vista USB Pnp driver model Hi All, I am working on USB PnP driver. I don't have sample code to start. Please help me where can i get the sample code. Regards, Suneetha Tag: WaveRT/WaveCyclic miniport usage and Vista certification Tag: 91132

We developed a virtual sound card driver and want it certified by Microsoft.
The purpose of the driver is to capture audio stream and then service that
we wrote sends it over the local network to networked speakers for playback.
So the driver itself doesn't work with any hardware.

Our current implementation (we support Windows 2000 and Windows XP 32 bit at
this time) uses WaveCyclic miniport.

We just started work on supporting Vista and got our driver working under
Vista with some minor changes. We are still using WaveCyclic miniport.

However, this document

http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/DrvCompat_Vista.doc

says:
==========================
The following list summarizes some key requirements for audio drivers:
· Implement Universal Audio Architecture (UAA)-compliant audio
devices.
· Implement audio drivers _as WaveRT_ miniport drivers.
· Implement up-to-date digital rights management (DRM) support.
==========================

Does it mean that if our Vista implementation uses WaveCyclic miniport we
will not be able to get it certified?

Also: who should I address this question to in Microsoft to receive
authoritative answer? I emailed to whqldt@microsoft.com but so far haven't
received even an acknowledgement that my email has been received.

As far as I know, the WaveRT requirement is only a "strong suggestion". I
has to be that way; the WaveRT model only applies to drivers that talk to
physical hardware. The model doesn't work for virtual drivers.

That is the correct address.
