    - KeStackAttachProcess Hello. I have written a driver routine that changes its thread context to make a quick read of RAM from another process. As the topic here suggests, it uses KeStackAttachProcess(), performs the quick read, and leaves with KeUnstackDetachProcess(). It is generally stableâ??I am not trying to read kernel RAM or anything dangerous so I donâ??t get any blue screens, but if the target process closes while my thread is over there my application deadlocks so hard it can not be closed by any means but a reboot. Is there any sure way to prevent this? I tried using CLI and STI but then I get blue screens whining about privilege levels. I use KeLowerIrql( DISPATCH_LEVEL ) but I get the same error anyway (I thought DISPATCH_LEVEL could always use CLI?). I think I could reduce the chances of this deadlock (currently at 94%â??if the target closes, my application WILL deadlock) using PsGetProcessExitProcessCalled() and then aborting if TRUE, but then I think this is only reduces the chances, not eliminates them. What if the process is closed after I call that function but before I go into it with KeStackAttachProcess()? Is there any way to get a brief lock that absolutely ensures the process cannot close while I am there? Thank you. P. S.: I call ObReferenceObjectByHandle() before going into the target process. This is supposed to raise the reference count on the process so it canâ??t fully close, which should have been preventing my problem. Am I being mislead?

    - Filter driver on 64 bit OSes Hi there, I just have finished up my filter driver writting on 32bit WinXP and Vista. The next thing I am currently doing is porting this filter driver to 64 bit OSes. I have this filter driver built with "Win XP 64 bit build Envirnoment" and it ended up these drivers neither work on XP nor Vista. From the registry, I can tell that the filter driver service has been loaded up but I can't see any my debug message print out from my driver. I have been searching on net and forums but nothing useful except this thing called "Kernel-Mode Code Signing". I start to suspect that my filter driver does not work mostly because of this so-called "code-signing policy". Does anyone can tell me am I on the right track? Many thanks in advance.

    - Help supporting WIA for a video driver I'm trying to get WIA working for a video camera using the AVStream class (based off of avshws). I have modified my inf according to the documentation (http://msdn2.microsoft.com/en-us/library/ ms792274.aspx), and the computer see the WIA device, but when I try to use any of the tools they never get beyond seeing the device. Using WiaTest, I can select my device in the new device dialog but when I click ok an error dialog appears. "CreateDevice failed trying to create a WIA device (The device is offline)". I haven't done any code to support WIA - are there functions that I need to support? How do they get called from an AVStream driver? Thanks, Matt Tag: Preinstalling Driver with DIFxApp Tag: 99785

    - How to identify whether a function pointer is valid? My USB driver sends Irp to query USB_BUS_INTERFACE_USBDI_V1 from bus driver. It returns STATUS_SUCCESS and fills the structure. I use USB_BUS_INTERFACE_USBDI_V1.IsDeviceHighSpeed() to query the device running speed mode. However, the IsDeviceHighSpeed() function pointer is invalid and not NULL. The system crashes immediately after the driver call the function pointer. The USB EHCI driver is 3rd party driver. I'm not surprised. I want to know how the kernel driver to identify whether the function pointer is valid before it calls the function pointer. Or how the kernel driver handle this kind of case.

    - Different unidrv.dll versions - which consequences do they have? We are using printerdrivers of HP, Kyocera and Lexmark which are based on the same set of unidriver-dlls. Unfortunately all three vendors use different versions of these dlls. We need to know the effects of the installation order on our printerdrivers. Here are the affected sets of dlls: Filename Fileversion Filesize Filedate unidrv.dll 0.3.1296.0 263680 03-25-2003 unidrv.hlp 18022 02-21-2003 unidrvui.dll 0.3.1296.0 203776 03-25-2003 unires.dll 0.3.1296.0 619520 03-25-2003 unidrv.dll 0.3.1296.4 264704 10-03-2006 unidrv.hlp 18022 10-03-2006 unidrvui.dll 0.3.1296.1 198656 10-03-2006 unires.dll 0.3.1296.1 619520 10-03-2006 unidrv.dll 0.3.3790.1830 269312 03-29-2007 unidrv.hlp 18022 03-29-2007 unidrvui.dll 0.3.3790.1830 207872 03-29-2007 unires.dll 0.3.3790.1830 620032 03-29-2007 1. Which changes have been applied between these dlls-versions ? 2. Do we need to follow a special order for the installation? 3. Does the unidrv.dll 0.3.3790.1830 still contain every api-function which is contained in unidrv.dll 0.3.1296.0? 4. Will any driver which was based on the first set of unidriver-dlls still work with the more recent set of dlls? Thank you very much for your support. Tag: Preinstalling Driver with DIFxApp Tag: 99770

    - SAA7134 & Texas XIO PCI-e-2-PCI bridge Hello All, I have a board with PCI-e-2-PCI Bridge XIO2000 from Texas and four SAA7134 Philips codecs behind it. Windows XP SP2 sees all four devices as being connected to some PCI bus. I have developed a driver for SAA7134 Philips codec and loaded it for all four devices behind this PCI-e bridge. I tested the driver with Philips devices on conventional PCI bus - it worked in the way I expected it. Everything changed with this new board. I have tons of mysterious errors. Trying to access one device memory mapped registers I affect register settings of another device on the same bus. I miss critical interrupts with almost enormous lag. Almost everything broke. My driver is conventional WDM. It uses memory mapped registers and interrupts line. SAA7134 performs bus master scatter-gather DMA video data transfer. So, here is the question - are there any special things about developing drivers for devices, connected to PCI-e bus? With best regards, Vladimir S.

    - Accessing disabled SCSI devices via Storport I am developing the SCSI device test application. It is intended mainly for SCSI device firmware developers and testers, and allows user to execute manually any SCSI command for the selected SCSI device. During the development and testing of the firmware the device might not be able to answer properly to SCSI commands. In this case it is necessary to disable the device object in the Device Manger window. Disabling the device object prevents the class driver from sending the SCSI commands for normal functioning. The special pseudo class driver was developed for the transparent device access. This driver sends IRP_MJ_SCSI IRPs with the SRBs directly to storage adapter objects (Scsi0:, Scsi1:, etc). This worked fine with SCSI Port but does not work with Storport. As I have learned from this newsgroup the Storport does not allow sending SRBs directly to adapter object. Sending SRBs to SCSI device object works fine but when the device is disabled there is no device object at all. The SCSI PASS THROUGH interface also does not work through the Storport for the disabled SCSI device. Is there a way to send the SCSI command to the disabled SCSI device via the Storport? Thanks a lot for advice. Tag: Preinstalling Driver with DIFxApp Tag: 99759

    - Video Controller not found in Windows 2003 Hi, I have a Windows 2003 server that, under Device Manager displays a question mark under the Vieo Controller. The Video card within the server is an ATI Radon X550. If I install the ATI supplied drivers the installation runs well yet Remote Desktop fails. If I uninstall the ATI driver, Remote Desktop works yet I get the question mark. Searching through the internet, it seems that Windows 2003 supplies its own ATI drivers. Is there a way I can reset this without having to reinstall the entire server. Thank You, Al Tag: Preinstalling Driver with DIFxApp Tag: 99758

I want to get the handle of the USB device, and the symbolicname of this USB device in register, like following: \??\USB#Vid_xx&Pid_xx#x&xx&x&x#{xxx..} somebody told me, this symbolicname can be used in CreateFile to create the handle.

    - delreg section in INF not truly deleting registry entry I have a heisenbug I could use help on. I have service that creates several registry keys. The service has an associated INF file which has a DefaultUninstall section which is called by our product's installer when removing the service. The DefaultUninstall section calls out a delreg section which deletes about 20 keys from the registry. All but one of these keys gets deleted correctly. Now for the heisenberg portion of the bug. The installer prompts the user for a reboot at then end of the removal process. If I pull up regedit before saying yes to the reboot, the key in question is indeed not in the registry any longer and is not when the system comes back from reboot. If I do not pull up regedit and just reboot, the key is still present when the system comes back from reboot. Obviously, regedit is causing the change to be permanent in some way. Is there some lazy write problem here? Is there a way from the INF I can flush or commit the reg changes? Thanks. Bill M. Tag: Preinstalling Driver with DIFxApp Tag: 99688

    - Verifier doesn't catch IRQL violation I accidentally called ZwReadFile at APC_LEVEL IRQL (holding a fast mutex actually) in a driver running on Vista RTM and got a weird result. ZwReadFile just wouldn't return. No crash, no bad status return, the thread just hung. Then of course the application was stuck with an open handle and neither the app or the driver could die properly. I turned on DriverVerifier for my driver with all options selected except low resource simulation and it never complained. It seems 1) ZwReadFile should be checking the current IRQL and returning a bad status if it isn't PASSIVE_LEVEL and 2) DriverVerifier should have caught this no? Just FYI to any MSFT folks that might care. I caught it pretty fast on my own, but this could cause someone no end of pain if they didn't know what to look for. Btw, this driver ran fine on XP SP2...don't know if that was (bad) luck or just a change in under arching operation. Haven't tried SDV on it yet. Bill M.

Everything works fine, we can install different printers and it works. The problem is when I reboot my PC, only the first installed printer is seen by the language Monitor. I can see all the printers in the "Printers and Faxes" window, but only the first one that was installed is polled by the language monitor.

    - Vista does not allow config space reads beyond 0xFF I have verified in winDBG in pci!PciExternalReadDeviceConfig that it checks the offset and verifies that the aligned offset is below 0x100. If it is at or above 0x100 then the returning status is 0xC0000010 or STATUS_INVALID_DEVICE_REQUEST which is exactly what I am getting. This is contrary to msdn documentation http://msdn2.microsoft.com/En-US/library/aa906253.aspx that says extended config space access is allowed: "Drivers can read from the extended PCI device configuration space (that is, more than 256 bytes of configuration data) using the IRP_MN_READ_CONFIG request or the GetBusData method of BUS_INTERFACE_STANDARD" Please tell me that I am wrong! I really would rather not calculate the offset from 0xe0000000 (using bus, dev, func) and manually read physical memory at that location to get to the extended config space. I WANT to use OS calls!

    - Ethernet driver buffer allocation This may not be the proper spot to post, but I figured it was a good starting point. I also suspect this may be dependent upon the actual Ethernet device driver, and not an industry standard. That being said: When data is transferred across an Ethernet connection using, say a TCP-IP socket connection, the end caller issues a receive call, and passes in a pointer to a buffer where the data is written. My question is: a) Is the data being transferred ONLY written into that buffer which is passed in, or b) is there an intermediate buffer contained w/in the driver to store the data as it is transferred across the medium (and then copied into the buffer passed in on the receive call)? I am trying to minimize copies in my code, because I have large amounts of data being transferred. Again, I realize that this may be totally dependent upon the ethernet card being used, I just was curious if there was an industry standard, or some underlying protocol/handshaking to which I was not aware of. Thanks. Tag: Preinstalling Driver with DIFxApp Tag: 99669

    - Getting started modifying a NT serial card driver to run on XP Hello I have the source code to a driver that works fine on NT4 but we now need to get it to work on XP. Our testing indicates that the driver does not work on XP. It is possible that it is a configuration issue however - as the driver gets some data from the registry - I am checking if we have that correctly configured. But I am guessing that is not the problem. Should a driver written for NT4 work on XP without change? The driver is for an RS422 multidrop card. Are there any areas of the driver code which I should be watching out for? Is this a total re-write situation or only minor changes? Any comments would be much appreciated.

    - Can't get reading extended config space to work on Vista I am pretty sure that the BIOS is allowing Vista to take control of PCIe since in WinDBG I can do a !pci 0x101 3 0 0 (my device is on bus 3, dev 0, func 0): ..[Config Space 0x00-0xFF omitted]... Enhanced Capabilities: 100: CapID 0002 Virtual Channel Capability Version 1 NextPtr 800 800: CapID 0001 Advanced Error Reporting Capability Version 1 NextPtr 000 However on another machine running Vista where I'm pretty sure the BIOS does not do the _OSC method and I think it is verified when I run !pci 0x101 on the same device there will be no "Enhanced Capabilities listing at all. Neither of the two Microsoft sanctioned ways (that I am aware of (i.e. GetBusData and IRP_MN_READ_CONFIG)) to access extended config space worked for me. I have even used the example verbatim from http://msdn2.microsoft.com/en-us/library/ms795302.aspx. The status returned from the IRP_MN_READ_CONFIG method is STATUS_INVALID_DEVICE_REQUEST. I've even tried installing Vista SP1 Beta, but the results are the same. Any other venues I should take/investigate? Thank you in advance. Gabe Tag: Preinstalling Driver with DIFxApp Tag: 99663

In worker function changes to files are done using e.g. FltSetInformation, FltWriteFile. This works very well. But user mode applications using NtNotifyChangeDirectoryFile or ReadDirectoryChangesW (e.g. Explorer) are not notified about these changes. Changes on files triggered from any user mode application are notified! How can I notify changes from IFS filter (system thread)? Tag: Preinstalling Driver with DIFxApp Tag: 99661

    - Multple LUN support question for USB flash drive Hi, I'm trying to expose a USB composite device with the mass storage interface at interface 2. Although I reported support for Hierachial support (HiSUP bit set to 1), the system does not try to query me for my other LUNs except for LUN 0. I never received the REPORT LUNS command that is suppose to be compulsory when HiSUP bit is set. When I change the mass storage interface to interface 0, I get the INQUIRY command for LUN 1 as well and all is well. Question is, why doesn't the system check for additional LUNS when my mass storage interface is not 0? Is this a requirement? Thanks. KS Tag: Preinstalling Driver with DIFxApp Tag: 99659

    - FTDI's FT232R chipset Junk data bytes Hi All, I am writing a Custom WDM USB-UART driver(Single VIRTUAL COM PORT) for FTDI's FT232R chipset. In my InitializationModule() and startdeviceroutine() I could able to Get the device descriptor and configure the Device perfectly. I am getting the Interface and pipe information correctly. My problem is after start device, If I try to Read data from the device by calling the following //Satrt the request ulFlags = USBD_TRANSFER_DIRECTION_IN | USBD_SHORT_TRANSFER_OK; UsbBuildInterruptOrBulkTransferRequest(pCtx->m_pUrb, sizeof(struct _URB_BULK_OR_INTERRUPT_TRANSFER), hPipe, pbBuffer, NULL, cbBuffer, ulFlags, NULL); // Setup completion proc IoSetCompletionRoutine(pCtx->m_pIrp,(PIO_COMPLETION_ROUTINE) RequestCompletedThunk,pCtx,TRUE,TRUE,TRUE); // Call next device with this IRP status = IoCallDriver(pCtx->DeviceExtension- >TopOfStackDeviceObject, pCtx->m_pIrp); in My Completion routine I am getting 2 bytes of junk data, Which is unexpected(There is no data kept in port). When I open the Virtual Com Port and write some data bytes, still I am getting these 2 junk bytes. I tried to resolve this issue by resetting the pipe. Still problem exists. Can anybody help me to get rid of that unnecessary junk bytes. Your valuable suggestions are always appriciated. Thanks in advance. ~Vijji Tag: Preinstalling Driver with DIFxApp Tag: 99656

    - NDIS Allocate memory fail??? Hi, I am writing a NDIM IM driver. In order to communicate with user land application, I allocate 3 buffers on nonpaged memory 10 MB each. My driver gets success to allocate memory in first time only for all buffers. Next time on wards, driver gets fail to allocate memory. I am very much sure that there is no any memory leak which I have tested. Please suggest me what should I do??

    - Driver Test Manager (2 tests fail in the unclassified tests) Hi, We are using the DTM (Driver Test Manager 1.0.6417.304) to test our kernel mode device driver (mirror driver) to get a digital signature. We are using the following configuration: Controller: Windows 2003 Server Studio: Windows 2003 Server Client: Windows Vista Home Basic We set up the unclassified tests and run them (we don't need a logo, we only need a signature). We received 2 errors in the following tests: - Run INFTest against a single INF (Error message in RunJob: Could not find user specified INF files) - Plug and Play Driver Test (3 Error messages in RunJob: DeviceId is NULL) Do you have any idea ?

    - Windows XP & non-paged pool Dear All, At my driver I need a really huge memory buffer. I am trying to allocate it from non-paged memory pool, since I need to perform a series of DMA transfers from lots of PCI devices installed in the system. Actually, every instance of my driver requires about 24 Megs of memory and we are planning to have about 16 such devices installed. What a disaster, I can load drivers only for 6 my devices, all other fail on allocating memory from non-paged pool. I decided to allocate memory from paged pool and lock it down in physical memory, using MmProbeAndLockPages(), but was able to load only 4 instances of my driver. What I am doing wrong?

    - IOCTL, DMA questions? Hello, I have some questions: 1). Can I create two DMA Transactions at same time using one DMA enabler? in what kind of case I can or canot? 2). If my IOCTL pass to kernel two buffers, one for read, and one for write, can I use this way in CTL_CODE?

    - IJolietDiscMaster->AddData returning STG_E_INVALIDFUNCTION Hi there, I am attempting to add a previously created IStorage container to an IJolietDiscMaster interface, although the file appears to have been created correctly and no errors were returned during it's creation, nor the streams that were added to it, unfortunately it returns STG_E_INVALIDFUNCTION. Could this be due to the way that I have created the streams? or not closed them correctly after adding data? Many thanks in advance as any help on this would be fantastic. Nick.

Do not use these WDK build environments for production-level coding. At this time, you should use the Windows Server 2003 SP1 DDK for production."

    - Win2k Host Controller question What is the GUID associated with a Universal Host Controller on Windows 2000 SP4 . For enhanced host controllers on Win 2k the symbolic link looks like this \\? \pci#ven_8086&dev_265c&subsys_01791028&rev_03#3&172e68dd&0&ef#{3abf6f2d-71c4-462a-8a92-1e6861e6af27} however i think that GUID #{3abf6f2d-71c4-462a-8a92-1e6861e6af27} is not associated with Universal Host Controllers. In that case what would be the GUID associated with the universal host controller ? Basically my final goal is to open a handle to the host controller using its symbolic link other than using \\\\.\\HCD%d the way USBview does ! Tag: Preinstalling Driver with DIFxApp Tag: 99592

    - talking directly to drivers Hello, I want to talk directly to the direct3d drivers without going through the COM direct3d api, I want to directly call D3dContextCreate, D3dDrawPrimitive2 etc. functions that are exposed by the driver. I want to reinvent the wheel, just as the COM d3d api usermode dll is one alternative to get to the driver, I want to make my own alternative. However I don't know how to do this. It all starts with an application in usermode loading my usermode dll providing an alternative to the COM api. How does my usermode dll penetrate into the kernel driver ? This is on xp I have downloaded the ddk, but haven't found an answer, it seems it's mostly targeted at writing the driver, not on how to program the 'other end' thanks, -- Sigurd Lerstad Tag: Preinstalling Driver with DIFxApp Tag: 99578

    - IMAPI Development Hi there, I am trying to write a C++ DLL that allows me to burn data CDs. I've been following the following article, http://msdn.microsoft.com/msdnmag/issues/04/04/CQA/ Unfortunately I am stuck as the CDiscMaster.GetActiveDiscRecorder fails, as does the SetActiveDiscRecorder method. The recorders are enumerated fine and I store them in a CSimpleArray object for index based referencing. I can acquire information on the recorders, i.e. Path and PnPID, but Eject does not work, nor does setting an active recorder as mentioned a moment ago. Any ideas what could be going wrong? Nick.

I want to install a signed USB driver with WIX 2 and DIFxApp.
This works as long as the USB device is connected to the PC during
installation. If no device is connected DIFxApp does not report an error and
adds an entry to Add/Remove Programs. But when I connect the device Windows
can't find the driver and asks for the *inf file.

The log reports the following:
DIFXAPP: INFO: No matching devices found in INF "foo.inf" on the Machine.
DIFXAPP: INFO: No drivers installed. No devices found that match driver(s)
contained in 'foo.inf'.
DIFXAPP: SUCCESS:Installation completed with code 0xE000020B.

So what can I do to preinstall a driver with DIFxApp?

Thanks,
Markus
