    - 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: Can't get stream point when attached two devices into a usb hub 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 ? Thanks, Olivier Tag: Can't get stream point when attached two devices into a usb hub Tag: 83317

    - 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) ? Second question : Irp->UserBuffer isn't NULL - can I use it instead of MdlAddress? Tag: Can't get stream point when attached two devices into a usb hub Tag: 83306

    - 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.

    - 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!

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)...

    - 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?

    - 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.

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.

    - 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.

    - Webcam "Hazy" effect on USB1.1 mode My webcam driver is based on "usbintel" sample in DDK src\wdm\videocap folder. 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? Is it related to the sensor settings or USB chip control? Any suggestion would be greatly appreciated~ Barry Tag: Can't get stream point when attached two devices into a usb hub Tag: 83201

    - 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: Can't get stream point when attached two devices into a usb hub 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!!

    - IRP_MJ_SCSI Hi All, I need to write a bus driver for a customer storage controller chip. 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. I am trying to decide between using the WDM and KMDF framework for writing this driver. From KMDF documentation I could not figure out what the framework entry point will be for IRP_MJ_SCSI. Is it possible to do this storage bus driver using KMDF? vs Tag: Can't get stream point when attached two devices into a usb hub Tag: 83180

    - How to inhibit Enabling of I/O Resource Hi everybody, I have a PCI device which is able to export its Control/Status Register space (4 KB in size) to both Memory and I/O Address Space. However, due to the fact that I/O resources requirements are reported in a single PCI BAR (which in fact is a PCI spec violation), I get a Code 12 error in Device Manager ("The device cannot find enough free resources that it can use"). In this case the last function code the PNP Manager sends is IRP_MN_FILTER_RESOURCE_REQUIREMENTS. The resource requirements list reads as follows: Resource Requirements: Number of Lists: 1 List 0: Descriptors: 7 Desc 0: - Option: preferred - Type: CmResourceTypeMemory Length : 1000 Alignmt : 00000001 Min.Addr: 00000000.c0000000 Max.Addr: 00000000.c0000000 Desc 1: - Option: alternative - Type: CmResourceTypeMemory Length : 1000 Alignmt : 00001000 Min.Addr: 00000000.00000000 Max.Addr: 00000000.00000000 Desc 2: - Option: required - Type: 0x81 - NAK Desc 3: - Option: preferred - Type: CmResourceTypePort Length : 1000 Alignmt : 00000001 Min.Addr: 00000000.0000c000 Max.Addr: 00000000.0000cfff Desc 4: - Option: alternative - Type: CmResourceTypePort Length : 1000 Alignmt : 00001000 Min.Addr: 00000000.00000000 Max.Addr: 00000000.ffffffff Desc 5: - Option: required - Type: 0x81 - NAK Desc 6: - Option: required - Type: CmResourceTypeInterrupt Min.Vector: 24 Max.Vector: 24 Filtering the above list in removing descriptors 3 through 5 from the list helps: I get an IRP_MN_START_DEVICE and resources look okay in Device Manager (no I/O address range is assigned). However, if I inspect the PCI config space of the device I see the I/O Space bit in the Command Register of PCI Configuration Space enabled. This happens even if the the I/O Space comes up disabled by BIOS. To be very clear at this point: - if there is no driver registered for the device, the I/O Space bit is left unchanged - if there is a driver registered but disabled the bit also is left unchanged - if the driver is enabled, then I/O decode is enabled (even if I tell the system I do not want/need I/O ports) How can I instruct Windows XP to leave the I/O resource disabled?

    - IoCreateDevice before or after IoInvalidateDeviceRelations I'm back-porting an XP WDM/PNP bus driver to W98SE (don't ask why!) and it seems that under 98 I must create a PDO for a newly-arrived device before I call IoInvalidateDeviceRelations, otherwise the driver does not get a following IRP_MN_QUERY_DEVICE_RELATIONS. Under XP the original driver was Invalidating the relations, then creating the PDO during the consequent IRP_MN_QUERY_DEVICE_RELATIONS handling. Is either ordering mandatory?

    - Serial Port Driver Hi! I want to write driver for serial port (COM), but I don't want support standard functions. For me that port has 2 outputs, 4 inputs and 1 interrupt source. Unfortunatelly I cannot "reserve" I/O ports and interrupt vector (IoReportResourceUsage fails) because standard driver has that resources for its own. When I turn off that serial port in BIOS, IoReportResourceUsage succeed, but writing/reading to/from output/input lines has no effect. Please for help, how to "disconnect" standard driver from one of serial ports (COM1 or COM2 - maybe another if exist) and "connect" to that port with my driver. Of cource my driver cannot figure as serial port on Windows' hardware list. Thanks for any suggestions. Best Regards. Tag: Can't get stream point when attached two devices into a usb hub Tag: 83159

    - IRP_MJ_READ asynchronous completion Hi, I am writing a driver for a device, which offers several interfaces - one of it is a virtual serial port. Within DispatchRead (for IRP_MJ_READ) I did as I read and thought that's correct, i.e. mark the irp pending, set a cancel routine, que it, and returned pending. I wrote a simple Win32 test program, which opened the port for overlapped IO and got the data back (if any available) with GetOverlappedResult. But the status returned by a call to GetLastError was still ERROR_IO_PENDING. When used with Microsoft Hyperterminal it seems that Hyperterminal did not get the information, that the IRP was completed at all. Thus I disabled all other interfaces and minimized my DispatchRead to the code below. It doesn't make much sense to mark the irp pending in that way but according the docs and info found on the web it should be allowed and working. IoMarkIrpPending(Irp); *((BYTE *)Irp->AssociatedIrp.SystemBuffer) = 'a'; Irp->IoStatus.Information = 1; Irp->IoStatus.Status = STATUS_SUCCESS; IoCompleteRequest(Irp, IO_SERIAL_INCREMENT); return (STATUS_PENDING); Still the same result. My Win32 program gets the data but does not get correct status information via GetLasterror and Hyperterminal does not recognize that the irp has been completed. Any idea what I do wrong or where I could have messed up my driver? Many thanks Werner Tag: Can't get stream point when attached two devices into a usb hub Tag: 83155

    - Serial Port Confusion I'm new to Serial communication, what I'm confused about is since data is being transmitted serially, should there be a clock signal as well for synchroisation. The output is a voltage for 0 or 1, how will the receiving device interpret this information without a clock? Can anyone guide me to some simple introductory material that can get me started with serial ports, I searched around but most of the articles was too much for me. I know C#/VB.NET and found articles that show me how to communicate serially but I need to know the exact working of a serial port.

    - NdisMEthIndicateReceive - no reaction Hi, I am developing application to encypt / decrypt TCP/IP packets data. I am using the PassThru driver extended by Thomas F. Divine (part 2 of his article). I change packet data outside the driver (in the application) so after decryption I want to indicate packet up. As a MiniportReceiveContext I use NULL, becouse I don't know where I could take it from (I thought that it is not necessary). My problem is very simple - after invoking appropriate ioctl code nothing happens. I used Ethereal to monitor packets and I can't see any of my packets (I hope I am right, that Ethereal looks above NDIS IM drivers). Please look at this little piece of code and tell me what the problem could be. Is it that MiniportReceiveContext or maybe something else. I use DbgView so I know that everything was invoked as I wanted. FltDevIoControl(){ (...) ioBuffer = pIrp->AssociatedIrp.SystemBuffer; inputBufferLength = pIrpSp->Parameters.DeviceIoControl.InputBufferLength; (...) case IOCTL_PTUSERIO_SET_INCOMING_PACKET_DATA: PUCHAR packetBuffer = NULL; UINT headerLen = 14; UINT payloadLen = inputBufferLength - headerLen; NdisAllocateMemoryWithTag(&packetBuffer, inputBufferLength, TAG ); NdisMoveMemory(packetBuffer, ioBuffer, inputBufferLength ); NdisMEthIndicateReceive( pAdapt->MiniportHandle, NULL, packetBuffer, headerLen, &packetBuffer[14], payloadLen, inputBufferLength ); break; } Thanks a lot in advance.

    - USB driver does not start after computer restart Hi everyone I am having some problems with an USB device supplied by our vendor. It comes with a standard .inf & .sys file. The first problem: even the driver can be installed properly in the first time, it always will not work after I restart the computer (it becomes Unknown Device inside Device Manager's Device List), I always have to unplug and replug the device again for it to work properly. The second problem: if I use MS devcon or Walter Oney's FastInst to install the .inf file automatically, I will always have BSOD right away. However, if I install manually by running the Windows Install Driver Wizard and select the .inf file, it can be installed without any problem. So my question is: is there a common mistake (e.g. forget to handling certain IRPs) that could cause the above two problems? I already ask our vendor and they seem quite clueless, so I would like to ask if anyone here have experienced it before and could shed some lights for me to speed up our vendor.

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!
