    - Diffrentiate bt USB MSD and USB HID Hi.. I recently wrote a driver which will block unblock a USB port...by way of intercepting the IRP requests. But the problem is that this driver dosent distinguish between USB mass storage device on one hand and other devices like USB HID. I need to specifically block USB storage devices like pen drives,USB hard drives etc,not any HID or other devices. Can anybody plz throw some light into it.

    - Authenticode problems under Windows 2003 I'm signing my drivers inf catalog file using a valid certificate issues by "Verisign Class 3 Code signing 2004 CA". Under vista, I see the following lines in setupapi.dev.log: (my certificate is installed in the trusted publishers store) ! sig: Verifying file against specific (valid) catalog failed! (0x800b0109) ! sig: Error 0x800b0109: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. ... sig: Error 0xe0000241: The INF was signed with an Authenticode(tm) catalog from a trusted publisher. sig: {_VERIFY_FILE_SIGNATURE exit(0xe0000241)} 06:02:44.054 According to Microsoft's "Troubleshooting Device Installation with the SetupAPI Log File" (SetupAPILog.doc), I should see the same log lines (and pseudo errors) in Windows 2003. Alas, I'm seeing ONLY the 0x800b0109 error line, which means (according to SetupAPILog.doc) that the driver does not have a WHQL catalog (indeed). It seems that for some reason, Windows 2003 doesnâ??t recognize my Verisign issued Authenticode certificate. The problem persist whether I'm using Microsoft-Verisign cross certificate (MSCV-VSClass3.cer) to sign my catalog or not. Any help would be appreciated...

    - newbie: remote installation with SetupAPI/Devcon.exe fails with ERROR_NO_CONFIGMGR_SERVICES. I try to access a remote machine with devcon.exe. For example: "devcon.exe -m:\\my_remote_machine classes" This always gives the error message "devcon failed". On the other hand it works, if I use my local machine name: "devcon.exe -m:\\my_local_machine classes" -> OK I debugged devcon.exe and found, that SetupDiBuildClassInfoListEx() returns a GetLastError()-code of 0xe0000223 = ERROR_NO_CONFIGMGR_SERVICES.

    - VSS hardware/software provider for Windows XP? Hi All, The VSS hardware provider API is supported only for Windows 2003 EE/DCE. VSS software providerÙ seem to work well under any Windows 2003 version and Vista, but fail to install in XP SP2. MSDN says that IVSSSoftwareSnapshotProvider interface is supported under Win XP too, but XP headers that come with VSS SDK 7.2 do not contain this interface definition. Does Windows XP support custom VSS software providers? Thank you in advance. -- Best regards, Valeriy Glushkov Tag: multiple video subdevices (avstream) Tag: 90118

    - NDIS6 NBL indication Hi I am writing an NDIS6 miniport driver and I have a question: I indicate NBL to NDIS using NdisMIndicateReceiveNetBufferLists. Those NBL are allocated using NdisAllocateNetBufferAndNetBufferList (i.e. each NBL is paired with a single NB). Each NB has a single MDL (which I allocated seperately using NdisAllocateMdl). When Ndis return the NBL to me (in MiniportReturnNetBufferLists) I notice that the NB containes now more than a single MDL (the original MDL is chained to another MDL). 1. Is that Normal ? i.e. can Ndis and above protocols can add MDLs to the NB after I indicate an NBL? 2. Should I release the new MDLs (which I did not allocated)? 3. Is it possible that Ndis will remove my original MDLs from the NB? In that case I guess that Ndis is also responsible for freeing it right?

We know we can not use logo after we pass the certification. Can we write "WHQL pass" on our product's specification documentations or the outside of box?? I have asked the support contact in Microsoft but he did not give me a certain answer. I am afraid we may have illegal issue if we wite "WHQL pass". Does anyone know this???

    - IRP_MN_QUERY_DEVICE_RELATIONS concurrency Is it possible to receive another IRP_MN_QUERY_DEVICE_RELATIONS for BusRelations while handling a different IRP_MN_QUERY_DEVICE_RELATIONS for BusRelations? (say on Windows 2000) I assumed not because I found no documentation for it. I have seen that white paper on IRP concurrency, but it failed to mention this one. I see "context of a system thread" mentioned in the DDK docs, which makes me think that might be the same system thread that sends IRP_MN_START_DEVICE, IRP_MN_STOP_DEVICE, and IRP_MN_REMOVE_DEVICE. Maybe I should just send every PnP IRP through my own worker thread, then I won't have to think about whether the OS serializes this PnP IRP or that one and why it does some and not others. I can't imagine PnP IRPs happen that often, so I can't imagine it'd be any sort of a performance bottleneck. Tag: multiple video subdevices (avstream) Tag: 90063

    - Mutual exclusion at passive level What's the standard way to call routines that are documented to require passive level inside code that needs to be mutually exclusive with some other code? A spin lock is out because it raises to DPC level, and I suppose dispatcher and fast mutexes are out because they raise to APC level. This APC level thing is what bugs me. It's sort of like passive level (preemptive) but sort of not, so maybe it's safe to call passive level code and maybe it's not. So, does this leave that trick with fast mutexes of combining KeEnterCriticalRegion and ExAcquireFastMutexUnsafe, or should I use a worker thread? (which seems kind of cumbersome) I wrote a bunch of code that very carefully holds a lock for as short as possible, grabs some information, does choice parts of its operations outside, then finally grabs the lock to store the result, but when I look at it I see it could be so much simpler if there was a safe way to make the whole large set of operations mutually exclusive.

    - ObReferenceObject while holding a spin lock ObReferenceObject can be called at DISPATCH_LEVEL, which means it both can run at the same IRQL as an ordinary spin lock and that it must not take very long to run. I can't imagine it calling back into my driver because it's probably not much more than an interlocked increment. Any specific reason ("no outcalls" is a little general) why ObReferenceObject should not be safe to call while holding a spin lock? (so that I don't have to go through my code and change some of my spin lock usage to a fast mutex) Tag: multiple video subdevices (avstream) Tag: 90058

    - __except_handler3 instead __except_handler4 Hello, I'm using the Windows Server 2003 SP1 DDK to build my drivers and I want to build also my MFC applications in the same build process (as I did it till now with the Windows 2000 DDK). The DDK has a compiler version 13.x. For the new MFC8 projects from VS2005 I need a compiler version 14.x from VS2005. I called vcvarsall.bat from VS2005 in my DDK environment, so I have the new compiler to build the MFC8 projects. After some changes for MFC_INCLUDES, MFC_INC_PATH, MFC_LIB_PATH my MFC8 compiles fine with DDK build. But I can no longer link my drivers, because __except_handler4 and __local_unwind4 are unresolved externals. cl.exe 13.x generates code with __except_handler3, which I can link with wdm.lib. cl.exe 14.x generates code with __except_handler4, which I can not link with wdm.lib. The MFC procject is linked with msvcrtd.lib, whichs contains __except_handler3 and __except_handler4. I have looked in the c2.dll of the cl 14.x. There I have found __except_handler4 and also __except_handler3. So I think, there must be a way to generate older exception handling with the new compiler. Who does know a compiler switch to generate older exception handling (__except_handler3) with the compiler cl 14.x from VS2005? Thanks, Volker Tag: multiple video subdevices (avstream) Tag: 90032

    - Bluetooth HID Currently the Wii Remote is a very hot topic because it works as a HID Bluetooth device. Unfortunately it does not work completely with the HID API and the Windows Bluetooth stack. I use my HID test programs developed for USB devices and with some of them it is possible to BSOD the XP Bluetooth stack. This is probably the uppermost HID driver not checking the parameters. I have seen that problem with an older Logitech mouse driver. I do not own a Wii Remote yet so i do not know much yet. Where do i get information about the problems of the Bluetooth stack?

    - Can not map the video memory into mapped file in mirror driver The problem have been resolved by doing as follow: 1. Delete the source code in DrvCreateDeviceBitmap, and just return NULL. 2. Delete the source code in DrvDeleteDeviceBitmap, and do nothing in it. 3. For other Drv* functions, call appropriate Eng* functions and return their value. For example, in DrvText Out, it will just call EngTextOut and return its value. Now the new problem is: 1. If the mirror driver's width/height/bitcount are different from primary driver's, it will still got black image. -- jarvisbao ------------------------------------------------------------------------ Posted via http://www.codecomments.com ------------------------------------------------------------------------ Tag: multiple video subdevices (avstream) Tag: 90013

    - NDIS 5.0 in Vista ? Hi Experts: I have a question on NDIS version usable under Windows Vista: We have been using an NDIS miniport driver writing using NDIS 5.0. Will this work under Windows Vista? If not, what should I do to make it work in Vista with minimum change? For example, should I port the driver code to NDIS 5.1 (which is supported by Vista as I read from the web)? If I port the code to NDIS 6.0, will the driver still work under older Windows platforms like Windows 2000 and XP? Thanks for your advises !

    - DIFx 2.1: Vista 64-bit signed driver install problem (CM_PROB_DRIVER_FAILED_LOAD) Hi! Windows Vista 64-bit build 6000: I´ve got a signed 64-bit driver package for a PCI device. A pure .inf installation works without any problems. The device will be installed properly. But the device installation fails using DIFx 2.1 on a clean system (device has not been installed before). I´ve created a MSI installer using the DIFxAPP 2.1 merge module. The MSI installation log file reports no DIFx error message but the setupapi.dev.log file reports: !!! dvi: Device not started: Device has problem: 0x27: CM_PROB_DRIVER_FAILED_LOAD. And Vista prompts with a "Program Compatibility Assistant - Windows requires a digitally signed driver" dialog. The MSI installation works only if the device has been installed through a pure .inf installation before at least. Looks like that the .cat file will not be copied into the CatRoot directory?!? I will check that out. And I will try the same scenario using DPInst.exe instead of the MSI installer, but I assume that will produce the same problem. Maybe I am doing something wrong. I hope that anyone of the DIFx team can help. Thanks! -Nick Tag: multiple video subdevices (avstream) Tag: 89972

    - NDIS6 - state machine and USB questions Hi everyone, 1. I am writing an NDIS6 virtual miniport driver and I am confused by the miniport and NDIS behaviour when I am disabling the device (through device manager). What happens is that Ndis calls MiniportPause, than it calls MiniportRestart and after that it calls MiniportPause again and finally it calls MiniportHalt. This confuses me since from what I understood from the state machine documented at WDK the sequence should be: a call to MiniportPause followed by a call to MiniportHalt - no call to MiniportRestart in the middle Is the sequence I see in my miniport indicates a problem on it or is it the normal sequence when disabling a device? 2. In the future I would like to turn the mninipot into NDIS + KMDF driver using USB. I would like to use the ContiniousReader mechanism. In NdisEdge sample it is written shortly about how to convert the sample to a USB but it is very general. So I looked at the WDK and at the osrusbfx2 sample and I saw that when using it on a KMDF driver one should do some actions on the following KMDF callbacks: EvtDeviceD0Entry (MiniportRestart ?) EvtDeviceD0Exit (MiniportPause ?) EvtDevicePrepareHardware (MiniportInitializeEx ?) EvtDeviceReleaseHardware (MiniportHaltEx ?) Writing an NDIS+KMDF miniport I don't have these callbacks what are the NDIS callbacks that complies to the these KMDF callbacks (I wrote my assumptions in parenthesis) ?

    - Can not map the video memory into mapped file in mirror driver I am writing a mirror driver to share the video memory with user-mode applications, here is my idea: 1. In DrvEnablePDEV, create a mapped file (such as c:\mirror.dat) for video memory by function EngMapFile, and store the mapped memory in the point pVideoMemory of PPDEV. The map will be unmapped and the file will be deleted in DrvDisablePDEV 2. In DrvEnableSurface, modify the surface with EngModifySurface.

I have written a new WDF driver and am in a quandary over what to do about the GUIDs. Our application requires that the interface class GUID remain the same. That implies that I should change the setup class GUID. If I do, do I need to change the ClassName too? What will happen when users update from the old driver to the new driver if the drivers have a different setup class GUID and ClassName? Tag: multiple video subdevices (avstream) Tag: 89943

    - Passing down IOCTLs I'm trying to figure out how IOCTLs make it all the way down to a PDO if they need to (for example through a disk class FDO down to a disk PDO, although I'm not sure there are other examples). For the subset of IOCTLs not supported by a generic FDO, is it conventional to use IoSkipCurrentIrpStackLocation and IoCallDriver in the dispatch routines for IRP_MJ_DEVICE_CONTROL and IRP_MJ_INTERNAL_DEVICE_CONTROL? I figure if the PDO doesn't recognize the requests it will just fail them anyway. The "DispatchDeviceControl in Higher-Level Drivers" section of the DDK docs seem to imply copying the current stack location to the next and installing a completion routine, but I don't see why this would be necessary if the FDO doesn't support the IOCTL and therefore doesn't need to do any post-processing on it. IoSkipCurrentIrpStackLocation seems more appropriate in that case. Tag: multiple video subdevices (avstream) Tag: 89927

    - Kmdf I have the old WDK (no wdf is included). Is it already too late to download the KMDF's release >= 1.1 separately ? It seems that the KMDF1.5 only comes with the latest WDK. Tag: multiple video subdevices (avstream) Tag: 89923

    - CreateFile faiedl with correct SymbolicLink Hi, dears! I added call to IoRegisterDeviceInterface() in AddDevice() for keyboard filter driver and it returned successfully with correct SymbolicLink ( checked in the registry ) like \\?\ACPI#PNP0303#4&4b018eb&0#{b4ee1d31-cbf8-400d-8d63-f99c500dbe76} but fail in HANDLE h = CreateFile(SymbolicLink, GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL,OPEN_EXISTING,NULL,NULL); for that ( I change '?' to '.' and so forth without success ) with error 2 ( ERROR_FILE_NOT_FOUND ). Is possible to open keyboard filter driver at all and send custom IOCTLs ? TIA Arkady Tag: multiple video subdevices (avstream) Tag: 89922

    - netvmini DHCP off, setting IP statically Hi everbody, Does anybody know if it is possible to change netvmini sample driver from DDK so that DHCP is off when installing the driver? If that is possible how can I set the IP statically? If is not possible, can I set DHCP off for my driver from a user application? How?

    - ieee1394 driver resume blue screen Hello I am using a driver for IEEE1394 DCAM-compliant cameras (sources can be downloaded from here http://www.cs.cmu.edu/~iwan/1394/downloads/index.html) When hibernating with this driver loaded, I get a blue screen at resume, with a NO_MORE_IRP_STACK_LOCATIONS message and a stop code of 0x00000035 The power management part of the driver is taken from the ieee1394 samples from the DDK, but apparently there is more to be done to make it work... Does anyone has an idea of how to solve this ? Or at least is there a way to prevent system hibernation if this driver is loaded ?

    - Emulate USB Modem device Hi, We have a requirement to emulate a USB modem device in order to test PDA functionality which is a host. I assume we would need to emulate a communication class device. We also need to send data back to host based on packets received from host. This would include call setup AT command responses and data packets after the connection is established. Does anybody know if this possible?

In general, i want to avssamp device appears in user mode under different
friendly names: avssamp1, avssamp2 and so on.

i am looking for way of creating several avstream filters with single KS
device installation.
i have found "Multiple Audio Subdevices" audio topic, that wrote about
customize INF file and use InstallSubdevice call in device startup.
Just want to find similar functionality in KS. Maybe it's possible to
customize avssamp KSDEVICE_DESCRIPTOR for it. Could anybody point me to
right solution ?

currently i see only one solution - multiple device installation,
modification of INF file to support several devices with different names
sharing one binary. i don't like it and want to know about possibilities...

Thank you.
