    - DIFx and virtual device drivers... I would like to use DIFx to install some virtual device drivers. Since these are virtual drivers I have to create the device instances manually. Is there a recommended way to do this with DIFx? DIFx appears to require a real device before it will create an instance. Is there a DIFx way to do this or should I use the SetupAPI and create the device? Robert Randall Tag: Does i/o read bytes perfomance counter includes paging operations(read page bytes)? Tag: 91445

    - How user mode drivers handle client application crash? Hello, I write a user mode USB driver which serves overlapped ReadFile requests from the client application. There will be exceptions in the driver when the client application crashes(or is closed by the Task Manager). Is there any special requirment for the user mode driver to handle this situation? BTW, I'm a newbie to the driver development. I'm using Vista and WDK. Thanks! zxli Tag: Does i/o read bytes perfomance counter includes paging operations(read page bytes)? Tag: 91438

    - Parallel Dispatching in KMDF drivers I have a PCI hardware with two communication channels. (A and B) Only DeviceIoControl() is used to communicate with this hardware, because there are In- and Outdata for each IRP. In NT4.0 driver I use the standard-queue for Type-A IOCTLs and a user-defined-queue for Type-B IOCTLs NTSTATUS MyDeviceControl(...) { ... switch(pIoStack->Parameters.DeviceIoControl.IoControlCode) { case IOCTL_MY_SIMPLE: // read some bits from hardware and complete IRP ... pIrp->IoStatus.Information=... pIrp->IoStatus.Status=... ntStatus=STATUS_SUCCESS; IoCompleteRequest(...) // no queue used break; case IOCTL_TYPE_A: ntStatus=STATUS_PENDING; IoMarkIrpPending(pIrp); IoStartPacket(...) // the default queue break; case IOCTL_TYPE_B: ntStatus=STATUS_PENDING; IoMarkIrpPending(pIrp); MyAlternateStartPacket(...) // my second queue break; ... } ... } -------------- Now I want to port my driver to KMDF. But I can define only one separate queue for Read, for Write and for IoControl. My Problem is, that I need two queues for IoControl like in my NT4.0 driver, because two User-Mode threads are communicating with my hardware (one thread with channel A, the other with channel B) Question 1: Is it possible in KMDF to return the IRP without using a queue (like IOCTL_MY_SIMPLE) Question 2: Can I direct my IRPs into different queues in KMDF? EvtIoDeviceControl is called for all types IOCTLs. (IOCTL_TYPE_A and for IOCTL_TYPE_B) Thanks Jacques Tag: Does i/o read bytes perfomance counter includes paging operations(read page bytes)?

    - Print Monitor Needs to Access Interactive Services I have a print monitor that is installed for a custom Postscript printer driver. This print monitor needs to display a screen asking the user to name a file and select some processing options during the call to LcmStartDocPort. It also invokes a COM object that display several interactive screens to process the file during the call to LcmEndDocPort. The printer driver and monitor installs and runs on OSes Win2K and up. It also installs on Vista, and it will properly interact with the user and process files as designed. However, on Vista the OS intercepts the dialog boxes and displays a dialog titled "Interactive Services Dialog Detection". The message is that "The program [my port monitor] may need information or permission to complete a task." When the user clicks OK, the dialogs are displayed. My questions: 1. How can I properly set permissions (programatically, during the installation) on the port monitor so that it can interact in the user session without the OS intercepting the dialog boxes? 2. Do these permissions need to be applied to the port monitor (a dll) or to the spooler that invokes it?

    - save string functions at IRQL > PASSIVE_LEVEL? I'm porting a big old driver to KMDF. I use some strcat()/strcpy()/sprintf(), often for internal diagnostic messages. They are now deprecated, and the recommended kernel mode replacement RtlStringCch*() functions are bound to PASSIVE_LEVEL. So what is your meaning about the best solution: Leave everything as it is and disable compiler warnings ? Or write my own strcpy_s()/strcat_s()/sprintf_s() ?

    - Does Longhorn driver work for W2K3 or Vice Versa Hi, I'm porting my driver to Longhorn, it's a boot-loaded driver supporting W2K3 32bit, W2K3 x64 and W2K3 ia64. Now we need to support Longhorn on all 3 platforms. Since for W2K3 support, I've built 6 drivers (free/checked, x86/x64/ia64). If for Longhorn, I build another 6, that'll be a lot. My questions are: 1. If I use WDK to build a driver for Longhorn in WDK Longhorn build enviroment, could that driver run in W2K3 on same platform ? 2. As a boot-loaded driver, to support Longhorn x64, it needs a embedded signature in driver file. If I do so, could this driver run in W2K3 x64 ?

    - DTM client configuration - is Autologon required? I successfully installed all components of DTM. I then decided to run some tests on sound card drivers currently used by computer on which I installed DTM client (this PC is running Windows XP pro if it matters). All these drivers are signed by Microsoft, so I expected that all test should complete successfully. Was my expectation wrong? Because they all failed. Looking at the test errors I see this several times: ================================= Failed to Wait For Autologon Error Code 0 (The operation completed successfully) Resolution Waiting for autologon in session 0 failed. If you have tasks depending on that session to be present then those tasks will fail until someone logs on to the session. ====================================== Does it mean that PC where DTM client is installed should be configured for Autologon? If yes - what user name should I use? I noticed there is DTMLLUAdminUser created by DTM Client installation, but if this has to be used - what is the password for this account?

    - VISTA Install Windows Drivers (Hardware-First Scenarios) I need to install drivers on VISTA and XP. I will provide a CD containing the drivers. As documented in the SDK and the WHDC site, I have added in my autorun.inf a new directive supported by VISTA, "hardwareid". This is my autorun.inf: [AutoRun] open=setup.exe [DeviceInstall] hardwareid= VID_413C&PID_5128, VID_413C&PID_5128&MI_00, VID_413C&PID_5128&MI_01, VID_413C&PID_5128&MI_02, VID_413C&PID_5128&MI_03, VID_413C&PID_5128&MI_04 DriverPath=\Drivers With VISTA, I am expecting the the "Found New Hardware Wizard" is stopped when I insert the CD containig the drivers, and launch my setup.exe that will preinstall the drivers (using the DIFx DPINST.exe) then give back the hand to the "Found New Hardware Wizard". But this is not the case. What is wrong with my autorun.inf. Olivier Tag: Does i/o read bytes perfomance counter includes paging operations(read page bytes)? Tag: 91379

    - NDIS: ProtocolUnbindAdapter() gets called at IRQL DISPATCH_LEVEL on Vista I got a problem, where ProtocolUnbindAdapter() of my IM driver gets called at IRQL DISPATCH_LEVEL on Vista, consequently causing a bugcheck 0x7C with 0x14,0x02,0x00,0x00 parameters when calling NdisWaitEvent() to wait for NdisCloseAdapter() to complete asynchronously. I'd like to know, why this can happen (most likely it's my programming error, but still), if the documentation clearly states that ProtocolUnbindAdapter() is called at PASSIVE_LEVEL IRQL. Also, the Debugging Tools documentation must be updated probably, since it doesn't reflect 0x14 parameter in the 0x7C bugcheck documentation. Additionally, when I specifically enable "DbgPrint buffering" parameter in GFlags utility and reboot the system and it crashes with a full memory dump, WinDbg then displays nothing when issuing ! dbgprint command. The nt!kdprint* buffers are empty for some reason. Thanks. Tag: Does i/o read bytes perfomance counter includes paging operations(read page bytes)? Tag: 91378

    - KMDF inconsistent compiling: order of struct { } members differs I'm writing a KMDF-driver with an IoCtl-Interface. For each IOCTL-code I have defined a C-structure which describes the data passed between driver and the application. These structures interpret the data buffer "inBuf" and "outBuf" on both sides of DeviceIoControl(). So I have several "typedef struct { ... } " declarations. These are located in a separate header .h-file, which is included both in the driver sources and the application sources. So it is garanteed that driver and applications use the same buffer-structures. PROBLEM: I have found at least one struct {}, where the compiler changed the field order, when he compiles the driver. Example: typedef struct { DWORD result; DWORD long_value; char string_value[MAX_STRINGPARAMLEN]; } MyRecord ; When I compile the APPLICATION and declare a variable "mybuffer" MyRecord mybuffer ; then the fields have physically those offsets: mybuffer byte 0..3: member ".result" mybuffer byte 4..7: member ".long_value" mybuffer byte 8..11: member ".string_value" = pointer to character-array = address of mybuffer byte 12 mybuffer byte 12 ... space for string This is as it should be: struct fields are allocate in the order they were defined. BUT when I compile the DRIVER, then there are those offsets: MyRecord mybuffer ; mybuffer byte 0..3: member ".result" mybuffer byte 4..7: member ".string_value" = pointer to character-array = address of mybuffer byte 12 mybuffer byte 8..11: member ".long_value" mybuffer byte 12 ... space for string So the order of members is NOT like defined, the members ".long_value" and ".string_value" were exchanged! The consequences are of course catastrophic, since the driver interprets the integer "long_value" as pointer to the character array "string_value" => end of live as we know it. Thanks for reading so far, I hope the problem is clear now. I searched a lot, but found no #pragma settings which could influence the ordering of struct-members. Only struct-aligning can be modified, but this is not my problem. Some more facts: - I use WinDDK 6000 - driver and application are compiled within the same run of the BUILD-utility - its a checked build for x86 and WinXP platform. - build environment is also an x86 machine with WinXP.

    - USB HID Lower Filter Driver issue under VISTA Hi, I have a problem under MS VISTA with a USB HID filter driver (I developped) attached as low filter on the USB common class generic parent driver (usbccgp.sys) for a USB keyboard device with extra keys. The goal of my filter driver is to change the behaviour or inibit some extra keys of the keyboard. The principle of the filter is the following: it change the HID codes output for the requested keys using a remapping table set in the registry (bytes of code to replace/ bytes of replacing code) and comparing incoming codes and replacing if codes are matching the ones for the keys. Inside the filter driver, the codes are catched thru IRP_MJ_INTERNAL_DEVICE_CONTROL IRP, then IOCTL_INTERNAL_USB_SUBMIT_URB control code, then URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER function. This filter driver works fine under Windows XP all version. But, now, under vista the filter is installing and running (i can see this thru debug outputs), but it doesn't filter anything: it doesn't catch anymore the function URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER even if i can see this URB with a sniffer (WDMSniffer). I am not a specialist in driver development and i don't understand what could have changed under Windows Vista comparing to Windows XP ? Does somebody has an idea?

    - NDIS 6 RSS: mapping between CPU number, MSI message, and queue I am working on an Ethernet miniport driver, and am confused about RSS. Suppose the NIC has 16 MSI-X messages and it supports 16 receive queues. According to the NDIS spec, the NIC should compute the target "CPU" as follows. Target CPU = indirection_table[hash & (table_size - 1)] & (# of receive queues - 1) + base cpu number. Computing this target CPU number is straightforward. But, how should the NIC map this number onto a specific receive queue and also the MSI message to generate an interrupt? The indrection table entries as well as the base CPU number may change over time according to the RSS spec. How does NDIS know that the NIC is interrupting the expected CPU?

I have too much data to store in the registry ( I don't know how much is too much, this may be an aesthetic issue), so I am considering storing it in an INI file. How do I know that the file system is ready for business? The info will be in a directory that the user creates. Typically it will be somewhere in C:\program files\...... , but not necessarily. When can I open this file? Gak - Finecats Tag: Does i/o read bytes perfomance counter includes paging operations(read page bytes)? Tag: 91327

    - PsLookupThreadByThreadId According to the documentation http://msdn2.microsoft.com/en-au/library/aa489311.aspx PsLookupThreadByThreadId() shall return a referenced pointer to the ETHREAD structure, however the function always returns STATUS_INVALID_PARAMETER, this is in XP SP2 called from a=20 ThreadNotifyCallback registered by PsSetCreateThreadNotifyRoutine(). How can I get a handle to the newly created thread? I need a way to inject a DLL in newly created processes without hooking CreateProcess. =20 Arno Garrels Tag: Does i/o read bytes perfomance counter includes paging operations(read page bytes)?

    - comparing all HW drivers on 2 servers Does anyone know of an easy way to compare the device drivers on 2 systems? I've got several supermicro 6014ptr boxes. one will occasionally freeze up - no network, no video, no kybd, etc. A couple others have frozen up similarly once or twice over the course of a year. I get no msgs in the system logs, the memory tests good (memtest86 for 16+ hrs) so I suspect device drivers. I've considered using MS System Information (winmsd), exporting to a file, then comparing, but I'd like to know if anyone has a better method to recommend. thanks!

    - Stream Class Custom Video Format Problem Greetings, I am trying to create a custom video format for a USB camera driver based on the Stream Class. I currently have support for RGB24 and RGB8 which works fine for just looking at the video stream. However, I need to support some extended information that I believe is best done via a custom format (namely 16 bit monochrome images and some extended timing information). This custom format is consumed by a specific usermode DSHow filter I am also writing. Everything starts off well: the format is negotiated and UM sink filter gets the expected format information. The pins connect and the stream opens (i.e. my camera gets a SRB_OPEN_STREAM and completes successfully). When I transition into run however, I never get any SRB_READ_DATA calls. I can easily still use the RGB24 and RGB8 formats so I know that the support code around the different formats is working. But there is something about this new format that I am missing. I suspect that I was relying on some KS behavior that is no longer present now that I have left the cozy KSDATAFORMAT_SPECIFIER_VIDEOINFO world. To implement my new format, I created two new GUIDs: MEDIASUBTYPE_MYCAM_RAW and KSDATAFORMAT_SPECIFIER_MYCAM_RAW_INFO There is an info structure to hold the format information: typedef struct tagMYCAM_RAW_INFO { // whatever... }MYCAM_RAW_INFO; And a data range and format: typedef struct tagKS_DATARANGE_MYCAM_RAW { KSDATARANGE dataRange; // I include nothing here because there is no "range" to speak of. The camera // only supports whatever its current settings are. } KS_DATARANGE_MYCAM_RAW; typedef struct tagKS_DATAFORMAT_MYCAM_RAW { KSDATAFORMAT dataFormat; MYCAM_RAW_INFO formatInfo; } KS_DATAFORMAT_MYCAM_RAW; The data range is static KS_DATARANGE_MYCAM_RAW StreamDataRange = { // KSDATARANGE dataRange; { sizeof (KS_DATARANGE_MYCAM_RAW), // ULONG FormatSize; 0, // ULONG Flags; [doc: ignored] 0, // ULONG SampleSize; [doc: ignored] 0, // ULONG Reserved; [doc: must be 0] STATICGUIDOF(KSDATAFORMAT_TYPE_VIDEO), // GUID MajorFormat; MEDIATYPE_Video STATICGUIDOF(MEDIASUBTYPE_MYCAM_RAW), STATICGUIDOF(KSDATAFORMAT_SPECIFIER_MYCAM_RAW_INFO) } }; It is possibly that my use of KSDATAFORMAT_TYPE_VIDEO (which I though was required for capture pins) is triggering some assumptions somwhere? Any thoughts would be most appreciated. Best regards, Tom Udale Tag: Does i/o read bytes perfomance counter includes paging operations(read page bytes)? Tag: 91324

    - WaveRT/WaveCyclic miniport usage and Vista certification 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.

    - 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.

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.

    - 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: Does i/o read bytes perfomance counter includes paging operations(read page bytes)?
