    - Device Name to Dos Name (IoQueryFileDosDeviceName) Hello all, I'm writing a kernel driver that needs the Dos name of a file (that's either stored on the hard drive or network). I'm looking for a function that converts a Device Name into an Dos name. For example: \Device\HarddiskVolume1\Windows\Explorer.exe = C:\Windows\Explorer.exe or \Device\LanmanRedirector\Server\Share\Folder\File.ext = \\Server\Share\Folder\File.ext Under Windows XP I can use IoQueryFileDosDeviceName (found it in the WDK) that does exactly this. But my driver also needs to work on Windows 2000. Is there another way to convert a Device Name to MS-DOS Name in a Kernel Driver? Kind regards, Erik Tag: How to add HDMI support in video miniport driver? Tag: 83472

    - Why no floppy tape drivers from Win2k on? When Windows 2000 came out, it removed support for floppy based tape drives (qic117.sys) What technical limitiation was introduced in Windows 2000 that didn't exist in Windows NT 4 that prevented Microsoft (and everyone else) from supplying a driver? It's not hardware, as my newest hardware (running NT4) still can use the device. It's not security with device abstraction, as it works on Windows NT. What is preventing everyone from creating a device driver for a floppy based tape drive? Tag: How to add HDMI support in video miniport driver? Tag: 83470

    - FsRtlIsNameInExpression All, I realise that this is slightly off topic for which I apologise but I think this newsgroup is the best chance I have of getting an answer! Does anyone know if there is a user-mode equivalent for FsRtlIsNameInExpression? I have to do some pattern matching in a native dll and I figured that if there is an equivalent anywhere in user-mode then this would be significantly less error prone than me knocking one out on a deadline. Many thanks in advance, Carl Tag: How to add HDMI support in video miniport driver? Tag: 83465

    - Filter Hook Hi, Drivers are very new to me, can someone help me with the next issue please: I have tried to set up a Filter Hook driver. I took an example code from codeproject (DrvFltIp) and it works ok on my computer (Windows XP). When I try to process the packets more thoroughly than in this example code, my computer crashed (freezes or restarts immediately). The crash happens when I do something that involves a KeWaitForSingleObject or a KeDelayExecutionThread call (but I am not sure these are the only scenarios that cause a crash). I looked in the dump file with WinDbg after the crash and saw that one of the last actions of the kernel were sending an interrupt and afterwards an exception. So my guess was that the kernel is sending a trap that was sent to it by the hardware to my driver to handle, but since I didn't set up an interrupt call back function, an exception is raised. The next thing I did was to try and set up an interrupt call back function, but this also caused a similar crash to the system (when I tried to pull out the parameters that I have to pass to the function "IoConnectInterrupt" from the isrStack). I tried to call the function "IoConnectInterrupt" from the function "DriverObject->MajorFunction[IRP_MJ_CREATE]" when got "IRP_MJ_CREATE" in "irpStack->MajorFunction" or when I got "IRP_MN_START_DEVICE IRP" in "irpStack->MinorFunction". When I tried even to access the parameter "irpStack->Parameters->StartDevice.AllocatedResourcesTranslated->Count" (even without calling "IoConnectInterrupt") it caused a crash. If anyone can help me understand what I am doing wrong, and why I am getting all these crashes I would be grateful. Thanks, Guy Tag: How to add HDMI support in video miniport driver? Tag: 83448

    - non-hardware driver? If I have a WDM kernel driver that I want to load that has no hardware associated with it (no PCI vendor/device ID), how do I get it to load? Under the 'old' model, I would make a DriverEntry() and call net start after modifying the registry appropriately. I don't see how to do that with WDM. 1. What do I put in the .inf file in the models-section-name and 2. How do I enable/disable/update it from within the Device Manager?

    - Can't get stream point when attached two devices into a usb hub Hi all, I encountered this issue when I attached two usb dvbt devices into my pc by one usb hub. I called KsPinGetLeadingEdgeStreamPointer in a system thread. Just after run the graph, KsPinGetLeadingEdgeStreamPointer could return stream pointer, but some seconds later, it always returned NULL. When I attached the two device into the pc directly(no through usb hub), it could work well. I have no idea about this issue. Could you gurus give me some comments or indicate how to debug this issue? Thanks! Tag: How to add HDMI support in video miniport driver? Tag: 83375

    - PCI bus, device, and function numbers from SetupDi? Is there a way to get the PCI bus, device, and function number for a device that works even when Windows has been localized to another language? I'm getting SPDRP_LOCATION_INFORMATION with the SetupDi functions and on an English system I get a string like "PCI bus 0, device 31, function 1" and I'm able to parse out the info. But if I'm running on the Japanese version of Windows XP, that string is in Japanese so the parsing fails. I can look for numeric digits and parse those in order, but that's a hack and I'm not sure if it will work on all languages since the string could be re-ordered. I looked around at the other SPDRP_* properties, but nothing seemed to contain the PCI bus, device, and function numbers. Is there some other way to do this?

    - Mapping multiple physical/system address virtual buffers into a single user-space virtual range. My question is as follows: Suppose I have a number of driver-allocated buffers. How can I map them into a single contiguous user-space buffer. I guess I should build an MDL that describes the physical pages mapped for these buffers and call MmMapLockedPagesSpecifyCache(), but did someone do this in practice? There seems to be no function to add several different pages to an MDL. Thanks a lot in advance, Greg. Tag: How to add HDMI support in video miniport driver? Tag: 83354

    - NDIS Protocol Driver and model OSI I am working with the standar NDIS and I have development my NDIS Protocol Driver using the NDISPROT of the Windows Server 2003 DDK. In the documentation about this matter I have read "network protocol" ,"protocol driver","NDIS Protocol Driver" and "transport protocol". I am confusing with those terms. Could you tell me the differences between them? Another question: If a "network protocol (i.e.TCP/IP)" is in the level 3 of OSI, and a "transport protocol" is in the level 4 of OSI, What level is the "NDIS Protocol Driver"? .I think level 3, is correct it??

    - Knowing a specific registry key before plugging a USB device Hello, My question concerns the way to know a specific registry key that is created by Windows the first time a USB device is plugged. Let me explain it in detail: When plugging for the first time my USB device (vid=xxxx, pid = xxxx) to a given USB port: Windows creates a specific key (for example 5&206acfca&0&1) under the directory: HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Enum\\USB\\Vid_xxxx&Pid_xxxx What I would like to know is how this key 5&206acfca&0&1 is generated and if it is possible to know it (with a function from Windows API) BEFORE the USB device is plugged. I have notice that this key is the same if the same USB device is plugged in the same USB port. To summarize: I have 6 USB ports in my computer and I know all information of my USB device, is it possible to know WITHOUT plugging my device each key (?&????????&?&?) of each port ?

    - IRQL He11 I am currently modifying a driver we use internally that interfaces with a PCI board. We are adding a DMA capability to the board where we can DMA data to and from specific memory regions, that is working correctly and I get interrupts and get into my DpcForIsr, etc, BUT what I need to do when I get data from the DMA is write it out to a file. Now, I know that in my Dpc I can't call ZwWriteFile to write out to my file that I opened previously, so I wrote code to setup a work item to do it for me. I am trying to copy the data from the NonPagedPool physical memory that the DMA is going into to another buffer that the work item can use to write to the file. I am having major issues because obviously RtlCopyMemory can't be called in the Dpc either because the IRQL is wrong. I tried getting an MDL and locking the pages in memory so they are resident before calling RtlCopyMemory, but I am having a heck of a time. If anyone can help out I would appreciate it greatly, below is the portion of the code that I am having problems with, it is contained in a DpcForIsr. // allocate a work item context pWriteCtx = (PWRITECTX_INFO) ExAllocatePoolWithTag( NonPagedPool, sizeof(WRITECTX_INFO), 'xtcW' ); // assign file handle pWriteCtx->hFile = pDmaStream->hFile; pWriteCtx->pBuffer = (U32*)ExAllocatePoolWithTag( NonPagedPool, pBuffer->Size, 'Wmem' ); if(pWriteCtx->pBuffer == NULL) { DebugPrintf(( "Insufficient resources to allocate work queue buffer\n" )); ExFreePool(pWriteCtx); } else { try { RtlZeroMemory(pWriteCtx->pBuffer, pBuffer->Size); pWriteCtx->bufferSize = pBuffer->Size; pMdl = IoAllocateMdl( pWriteCtx->pBuffer, pBuffer->Size, FALSE, TRUE, NULL ); pMdlDma = IoAllocateMdl( (PVOID)pBuffer->UserAddr, pBuffer->Size, FALSE, TRUE, NULL ); MmBuildMdlForNonPagedPool( pMdl ); MmBuildMdlForNonPagedPool( pMdlDma ); MmProbeAndLockPages( pMdl, KernelMode, IoWriteAccess ); MmProbeAndLockPages( pMdlDma, KernelMode, IoReadAccess ); // // Map the physical pages described by the MDL into system space. // Note: double mapping the buffer this way causes lot of // system overhead for large size buffers. // pTempBuf = MmGetSystemAddressForMdlSafe( pMdl, NormalPagePriority ); pTempDmaBuf = MmGetSystemAddressForMdlSafe( pMdlDma, NormalPagePriority ); // copy the data from the buffer into the work queue buffer RtlCopyMemory( (VOID*)pTempBuf, (VOID*)pTempDmaBuf, pBuffer->Size ); // unlock the pages and free the MDL MmUnlockPages( pMdl ); MmUnlockPages( pMdlDma ); IoFreeMdl( pMdl ); IoFreeMdl( pMdlDma ); pBuffer is the buffer that represents the DMA buffer where the data from the DMA is located. My work item context structure looks like this: typedef struct _WRITECTX_INFO { PIO_WORKITEM item; DEVICE_EXTENSION *pdx; U32* pBuffer; U32 bufferSize; HANDLE hFile; } WRITECTX_INFO, *PWRITECTX_INFO; I am very new to driver development, so I know I am doing something wrong (obviously or it would be working).

    - Irp->MdlAddress is NULL Hi, I'm writing a network driver based on passthru sample. I want to add ReadFile function. I saw a sollution in the other sample (called ndisuio) so I try to do it in the same way. But in ...ServiceReads funtion Irp->MdlAddress is NULL. I don't have any idea why. I checked that in Ndisuio there's no function like MmBuildMdlForNonPagedPool or MmProbeAndLockPages, is it ok (I read DDK and they seem to be necessary) ?

    - pci bus discovery According to white papers when the bus driver pci.sys discovers a bridge device, it will determine if the device is initialized and if not, it will assign the default values to the secondary interface of 64MB Memory, 64MB Pre-Fetch and 4K IO (assuming the upstream device has enough available as well.) What I have never heard is how pci.sys determines whether to assign the default values or not. I had initially assumed it was looking at the Command register (offset 0x04). I had initial success with experimentation on this assumption, but I have recently discovered the following cases: 1. The Command register is set and resources appear to be assigned by the BIOS, but pci.sys assigns new resources to the default values. 2. The command register is 0, but pci.sys does not assign resources to the secondary interface, it sets the command register and leaves the rest of the configuration space alone. In the former case the problem must be in the BIOS. The latter case was discovered while testing hot-plugging on a PCI-Express device so the problem is most likely in the device's EEPROM. The latter case was also seen in both XP and Vista. Knowing what pci.sys is doing here would be helpful to anyone developing devices with bridges, or writing the BIOS/UEFI.

    - Writing driver for blocking IO ports Hi .. I need to implement an IO port blocker in the form of a WDM driver(filter driver).I will start with the elementary case namely the blocking of the parallel port.Any ideas about how to proceed? Will completing IRP_MJ_READ/IRP_MJ_WRITE using IoCompleteRequest work or is there any other way out? Regards DC Tag: How to add HDMI support in video miniport driver? Tag: 83282

    - One driver for two device? I have implemented a bda driver for our usb device. Now, we should support MCE, which requests the driver to support two devices on one hub. After refer to ddk sample, generictuner, I implemented GetMedium method in the tuner filter, like following: ---8<--------------------------------------------->8--- CFilter::GetMedium(IN PIRP p_irp, IN PKSMETHOD p_ks_property, OUT KSPIN_MEDIUM* p_ks_medium) { NTSTATUS status = STATUS_SUCCESS; if (p_ks_medium == NULL) { p_irp->IoStatus.Information = sizeof(KSPIN_MEDIUM); return STATUS_MORE_ENTRIES; } PKSFILTER p_ks_filter = KsGetFilterFromIrp(p_irp); if (p_ks_filter == NULL || p_ks_filter->Context == NULL) { status = STATUS_INVALID_PARAMETER; return status; } CFilter* p_filter = (CFilter*)p_ks_filter->Context; if (p_filter->m_p_device == NULL) { status = STATUS_INVALID_PARAMETER; return status; } p_filter->m_p_device->GetInstanceID(p_ks_medium->Id); // So, we only support two instances now. if (p_ks_medium->Id == 0) { p_ks_medium->Set = GUID_FIRST_INSTANCE; } else if (p_ks_medium->Id = 1) { p_ks_medium->Set = GUID_SECOND_INSTANCE; } else { p_ks_medium->Set = KSMEDIUMSETID_Standard; } p_ks_medium->Flags = 0; return status; } ---8<--------------------------------------------->8--- But after I enabled this method, the two filters, tuner and capture, could not be conneted successfully. Did I missed something? Or may I misunder the medium? Did the Medium use to differentiate the instances from one driver? Any comments are welcome! Advance thanks!

    - DeviceIOControl to mouse driver.. Hi, We are developing a USB mouse driver and also its utility.. If the class name was assigend as USB in the inf file (ie, the deivce would be listed in the USB in the device manager), we find our utility could communicate with our own mouse driver without any issue. Well, if we change the class name from USB to Mouse in the inf file..(ie., the device would be listed under Mouse in the device manager).. the same code "DeviceIOControl" would return an error code "1" (Invalid function)... Could anyone provide a hint for that.. Thanks. -chueh8 Tag: How to add HDMI support in video miniport driver? Tag: 83268

    - How to Link USB audio device ID with Hardware MID&PID My question is: How to get the exact link between high level device ID and Hardware MID&PID of an USB audio device? Or how to get the high level device ID of a given MID&PID? Especailly when mutiple USB device is plug-in. What we have tried: We can open a particulary USB audio device by the device ID, such as using uDeviceID to open a wave-audio by WaveInOpen() function. And we can also get the Hardware MID&VID by other functions. It's supposed that function like waveInGetDevCaps() can get MID&VID for a given uDeviceID to build the link. However, by using waveInGetDevCaps(), we always get: mid = 0x1 pid = 0x65 according to definition: #define MM_MICROSOFT 1 /* Microsoft Corporation */ #define MM_MSFT_WDMAUDIO_WAVEIN 101 /* Generic id for WDM Audio drivers */ Could anyone help with solving this issue? Thanks! Tag: How to add HDMI support in video miniport driver? Tag: 83267

    - UMDF driver debugging Hi, I am studying UMDF driver now. I am trying to use WinDbg to trace "echo" driver (sample in WDK). After application open the driver, I try to set breakpoint into driver, but WinDbg can not find the code and symbol. (I already set file path.) WinDbg could debug UMDF driver ? Also, do UMDF driver cound use assembly for I/O. I am tring to use : mov al, 60h out 80h, al , but it seems not work. Jacob Tag: How to add HDMI support in video miniport driver? Tag: 83266

    - Cannot open $MFT::$BITMAP attribute Hi I'm trying to open $MFT::$BITMAP file to defragment it and get error "file not found". The file is opened by a NT native application at boot time so it's not a problem with access rights, moreover other system locked files (pagefile.sys etc.) can be opened normally. I guess the file name/path isn't formatted correctly although other similar files like $Secure:$SDH:$BITMAP are opened without problem. Can anyone shed some light on this problem please?

    - Having a problem of Vista XPSDrv filter to call an entry in other I built a pass through filter(stream in and stream out) and it worked fine. Then I tried calling an entry to one DLL built by VC8 or WDK. But the filter failed to load. The linker linked correctly. I think it might be caused by incorrect building process of the DLL. Can anyone give me some simple sample(codes, build file, environment) which works? Thanks. Tag: How to add HDMI support in video miniport driver? Tag: 83263

    - Windows XP Driver Hang I have written a driver for a PCMCIA serial device. This device uses the underlying Microsoft Serial Driver (serial.sys) to communicate with the hardware. The problem I am having is that it hangs when I use the driver under Windows XP for the first time. The circumstances in which it hangs are strange. I take a Windows XP system that has never seen this driver and install it and reboot the computer. I plug the card in the laptop and windows recognizes the driver and installs the unsigned driver. Thereafter I can write data to the driver the first time and it responds properly but when I try to write data the second time the OS freezes. I was debugging the driver code step by step and I noticed that the IRP that I send to the serial driver is completed and the completion routine is called but half way in to this routine suddenly the system freezes. It does not happen on the same line of code but it does happen in the same function. When I look at the stack I don't see my driver anywhere. I belive that something else is causing the freeze. But this only happens once after that I can write and read data and there is no problem at all. Any help is welcome. Thank you, Shreyash B.

    - hyperthreading prevents printer driver installation Hi, I'm having a problem with our printer driver in Windows XP Professional when hyperthreading is turned on in the BIOS. It attempts to install but looking at the error log it says that Windows deletes the printer afterwards. The driver has a IPrintOemUI COM interface to add a tab to the property pages. I built this driver using an old Windows 2000 DDK. Should I be revising it? Tag: How to add HDMI support in video miniport driver? Tag: 83242

    - NDIS driver install by snetcfg.exe help! Hi everyone, I write a NDIS driver and use "Local area network property" to install driver, and it 100% success. If I used "snetcfg.exe" for programatical install my NDIS driver at the computer logon then I get blue screen randomly, I think about 70% success. For cases that success, Device Manger->Network adapter showed: -Network adapters --Intel(R) PRO/100 S Dual Port Server Adapter --Intel(R) PRO/100 S Dual Port Server Adapter - My Sample Virtual adapter --Intel(R) PRO/100 S Dual Port Server Adapter #2 --Intel(R) PRO/100 S Dual Port Server Adapter #2 - My Sample Virtual adapter Everytime the installation failed it give me a Blue Screen and automaticly reboot the node. Then it kicked off the snetcfg.exe to install again. I checked in the Device Manager->Network Adapters showed: -Network adapters --My Sample Virtual adapter (extra stand alone,I think this is causing blue screen) --Intel(R) PRO/100 S Dual Port Server Adapter --Intel(R) PRO/100 S Dual Port Server Adapter - My Sample Virtual adapter --Intel(R) PRO/100 S Dual Port Server Adapter #2 --Intel(R) PRO/100 S Dual Port Server Adapter #2 - My Sample Virtual adapter My guess is timing, when snetcfg.exe start install and the network adapters are there but not fully functioning/binding yet. and when snetcfg install it couldn't find the adapter to bind and it just install the Ndis driver as a stand alone network adapter. Please correct me if I'm wrong... My question is: how do I check if network support is ready/fully functioning inorder for me to install 100% sucess. OR is there any other hints/method for me to avoid the blue screen and also the driver work properly by using snetcfg.exe to install. Many many thanks for any help! ttan Tag: How to add HDMI support in video miniport driver? Tag: 83239

When I use new ddk compiler, I see driver binary size significantly increase (~2k), and driver gets a blue screen if the interrupt routine is enabled, which practically do only a msr write function. This msr write operation was safe with ddk build 1069. Any input? Thank you, RJ Tag: How to add HDMI support in video miniport driver? Tag: 83238

    - How much knowledge of OS is required using WDF? Hello, everyone. I¡¯m an undergraduate student who is looking for a job. Because I don't know anyone who writes device driver, I really want to listen to your opinion. When I was reading the book Windows Internals, I¡¯ve realized that a lot of sections are targeted to device driver developers. Because I enjoyed the book, I¡¯m considering getting a job that I can learn about Device Driver development. However I think that WDF is trying to isolate device driver from the operating system. I¡¯m afraid that I may loose interest because of that. I want to know about, How much work will be done using UMDF? (not by category of technology but proportion of jobs) And how much and concrete knowledge about Windows kernel is needed when using KMDF comparing to WDM? Thanks in advance.

We changed it to support 64-bit system but encountered a problem when connect the device to USB1.1 port (via a USB1.1 hub which connect to a USB2.0 port on motherboard) on 64-bit XP. The issue is : preview effect is hazy, it's like cover the preview window by using a gray semitransparent cloth. I have no idea how come that happened?

    - Suppress command window wile using IExpress wizard Hi all, I'm using IExpress wizard to create a self extracting driver package. I use a command-line script to create some directories in the extraction path and copy some files into them. I'm using DPInst to install the driver files onto Vista systems. My questions are; 1. How I can suppress or at least minimize the ugly command window that pops up when the command-line script runs? 2. Some of the buttons on the DPInst screens seem to be redundant... such as the Finish and Cancel buttons on the finish page seem to do the same thing. How can I get rid of the redundant buttons on the DPInst screens? Thanks in advance, Shaji. Tag: How to add HDMI support in video miniport driver? Tag: 83196

    - Interfacing to Com port driver I am attempting to interface to a piece of equipment which provides serial port emulation via its driver for USB. When it is plugged into different USB ports, it appears at different com port addresses - i.e. COM8: or COM12: (on my machine). I have two specific quistions: 1) How do I open a COM port greater than COM9:? When I try to use the recommended procedure (open as a file), it fails if the COM port number is greater than 9. 2) How do I find which COM port number the device is connected to? It manifests as a modem, and has a specific device name which I can see in Hardware Manager. If I examine the advanced port properties, I can see which COM port number it has assigned. I need to find the device by name (or see if it's not there). How do I do this? I am using Visual Studio 2005 and writing in ANSI C.

    - Windows Vista Printer Driver and Printer Name Hello all, I've developed a user mode printer driver. Until Windows Vista it never had any problem. In Vista, when installing from remote server, the printer name that gets into DrvPrinterEvent, with PRINTER_EVENT_INITIALIZE, it's something like this "\\CSR|ServerName\{94718C2F-E998-90E2-2CA0E49A1C12}. What does this printer name means? I've also noticed that there are additional registry keys under "HKLM\Software\Microsoft\Windows NT\Print\Providers\Client Side Rendering Print Provider\Servers\ServerName\Printers\{94718C2F-E998-90E2-2CA0E49A1C12}" What Keys are these ones?? The driver uses my own Language Monitor, which will write specific data under PrinterDriverData, normally it was written under HKLM\System\CurrentControlSet\Print...." but now where should it be written? Strange it's the name that get's into DrvPrinterEvent! it should be something like \\ServerName\\Printer Name" !! And PRINTER_EVENT_INITIALIZE gets called like 6 times in a row, and when I try to print nothing happens. No StartDoc, no closeport, nothing!!! It worked ok two times, and at this time I've noticed that local registry settings were the same as in Server registry. Help me please!! Tag: How to add HDMI support in video miniport driver?

I cannot use the SCSIPORT model as the enumeration of the devices is very specific and I feel writing a bus driver will provide me the most flexibility to do this.

Now the interface between the display card and monitor changes to HDMI from
VGA interface. I don't know how to modify the video miniport driver to
support HDMI interface. As I know in the VGA compatible video miniport
driver, I need to implement SVGA functions. Now for HDMI, what should be
done?
