 - zwwritefile return STATUS_INVALID_PARAMETER Hi, Sometime I receive the value STATUS_INVALID_PARAMETER from ZwWriteFile, my device work in Win 2000/XP. I create a file with ZwCreateFile (I use the OBJ_KERNEL_HANDLE) I call ZwWriteFile from a WorkItem, so I'm at Passive_Level. This is my code: // Create the file and in hFile I have the handle ntStatus = MyCreateFile (&fileNameUnicodeString, &hFile, FILE_OVERWRITE_IF); After I queue a WorkItem for write in my file // My code in WorkItem: // I use PagedPool because I'm at IRQL PASSIVE_LEVEL (WorkItem) pNewbuff = ExAllocatePool( PagedPool, BytesAvailable); ntStatus = WriteFile (hFile, (PVOID) pNewbuff, BytesAvailable, &dwBytesWrite2, NULL); Sometime ntStatus = STATUS_SUCCES, when I stress my device ntStatus is STATUS_INVALID_PARAMETER Do you have an idea ? These are my function MyCreateFile and WriteFile: NTSTATUS MyCreateFile (IN PUNICODE_STRING pUniFileName, OUT PHANDLE p_ntFileHandle, int TypeDisposition) { NTSTATUS ntStatus; OBJECT_ATTRIBUTES oa; IO_STATUS_BLOCK ioStatus; InitializeObjectAttributes( &oa, pUniFileName, OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE, NULL, NULL ); ntStatus = ZwCreateFile( p_ntFileHandle, GENERIC_READ | GENERIC_WRITE | SYNCHRONIZE, &oa, &ioStatus, NULL, FILE_ATTRIBUTE_NORMAL, 0, TypeDisposition, FILE_NON_DIRECTORY_FILE | FILE_SEQUENTIAL_ONLY | FILE_SYNCHRONOUS_IO_NONALERT, NULL, 0 ); if( !NT_SUCCESS( ntStatus ) ) { DbgPrint(("Could not creAte file, status: %x\n", ntStatus )); } else DbgPrint(("file create handle: %x\n", *p_ntFileHandle)); return ntStatus; } NTSTATUS WriteFile (HANDLE hFile, PVOID lpdat, DWORD size, DWORD *dwBytesRead, PVOID p1) { NTSTATUS ntStatus; IO_STATUS_BLOCK ioStatus; ntStatus = ZwWriteFile (hFile, NULL, NULL, NULL, &ioStatus, lpdat, size, NULL, NULL); *dwBytesRead = (DWORD)ioStatus.Information; return ntStatus; } Best regards Gian Tag: Where I can download DDK?

 - Restricting access to USB devices Hi All, We have two requirements in our project, it is related to USB devices in WDM. We don't have much idea regarding the USB devices and USB class drivers. So I hope I can get some guidance from this group regarding my problem. Operating System : Windows XP Embedded. One requirement is, support only few specific USB devices in the machine. All other USB devices should be blocked. The following are the USB device classes to be supported in the machine. a. Human Input Devices (HID), b. Chip/Smart Card Interface Devices (CCID) c. Various Mass Storage class devices (MSC). E.g.. Smart Card d. Audio and Modem devices Our Current Idea for implementing this ---------------------------------------------- Remove the class drivers of the classes of devices to be blocked. Some of the classes we identified to be removed are listed below. a. Printer Class (usbprint.sys) b. Communications Device Class (mdismp.sys) c. Imaging Class (usbscan.sys) d. Hub Device Class (usbhub.sys ) This can be done while configuring embedded Windows XP. Will be there any problem if we remove these drivers ? The second requirement is that the read/write access to the supported USB devices should be controlled. i.e.. if it the permission set is READ_ONLY, only read access will be allowed. Our current Idea for implementing this ------------------------------------------- 1. Write a USB filter driver ( Say, usbmon.sys) 2. Install it as a 'class upper filter driver' to the required classes of devices. a. Human Interface Device (HID) Class. (hidclass.sys) b. Audio Class (sysaudio.sys) c. Mass Storage Class (usbstor.sys) 3. Export a IOCTL from usbmon.sys so that user mode applications can control the read/write operations to . Is there any better idea for implementing these things. Are we in right direction? Please advice. Thanks in advance, vasanth. Tag: Where I can download DDK? Tag: 54630

 - WDM Wizard Walter Oney Hello, I am trying to develop a WDM driver with the WDM Wizard that comes with Walter Oney´s Book, I am able to create a project without or with generic.sys, and also I can compile them but when I install it in the system using the .inf file the Device Manager show that there is a problem with my driver, and the message is that: "This device cannot start. (Code 10)" I did not make any change in the walter oney´s wizard generated driver, so I guess it should work, without any functionality but I just want to see that is ok. There is something that is necessary to do before compiling, like adding some code, because I just have used the fixproj.exe that the book says to execute. If you have any idea please tell me. regards Guilherme Francisco Mallmann Tag: Where I can download DDK? Tag: 54619

 - Set the postscript dirver option TTDownloadFormat ("TrueType Font Hi, I asked this question in 3 other newsgroups (microsoft.public.windows.print, m.p.w.print_fax, m.p.w.printing), but didn't get a reply about what I needed, So I'm trying here again. Any pointers to other newsgroups that may help will also be appreciated. I'm trying to write a program that creates a printer, with a driver based on the MS PS driver and a ppd I supply (it has to run under windows 2000 and XP). If I do this, the printer created has an advanced option "TrueType Font Download Option" (in XP under the printers 'printing preferences', then 'Layout/advanced/Document options/PS options/TrueType Font Download Option'). I'd like to set this option to 'Native TrueType' when creating the printer (or right after it). I have found no way to do this short of looking at which bits in the devmode's driver specific portion change and redo that change using GetPrinter/SetPrinter (I understand from what I read however that fiddling with the driver specific portion of devmode like that is a very bad idea). There seems to be a way to set this through IPrintCoreUI2::SetOptions, at least that's the only 'SetOptions' I can find that this article could be talking about: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_9c9f919f-341e-45bb-ab32-a8e215cecb41.xml.asp However, from what I understand, this call is designed to be called from a printer property sheet, and structures made available by the system that calls the property sheet (first parameter: "poemuiobj Points to the current context, an OEMUIOBJ structure.") Does anyone know a way to set this option? ---clarification based on earlier answer--- Note that this is not the dmTTOption memeber of DEVMode, that sets 'Layout/advanced/graphic/TrueType Font' (which has options 'Download as Softfont' or 'Substitute with device font'), while the option I'm looking to set is under 'Layout/advanced/Document options/PS options/TrueType Font Download Option' (which has options 'Automatic', 'Outline', 'Bitmap' and 'Native Truetype'), but only for printers that use the microsoft PostScript Printer Driver (Pscript, documented at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_ccdc3e30-0b44-4ada-b51a-8c0d0bfd5997.xml.asp). It is specific to Microsofts PostScript Printer Driver (I think), and is described as "Driver features are non-PPD features that are synthesized by the driver" here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_a64f2cd3-6775-4121-98b1-7470c302574f.xml.asp Thanks for any help anyone can give me.

 - Microsoft please help! NDIS Intermediate driver bindings We have written an NDIS intermediate filter driver that binds to TCP/IP at its upper edge and a network adapter at its lower edge. If another intermediate filter driver is installed as well, the new driver either sits above our driver or below it in the stack. Is there a way that I can force our driver to always be above the other intermediate - we always want to see the traffic coming directly from TCP\IP and not from some other intermediate driver above that might be above? I suppose the question I'm asking is, is there a way to control the ordering of intermediate drivers when there are several installed on one system? Tag: Where I can download DDK? Tag: 54614

This usually indicates problem with the hardware itself or with the device driver programming the hardware incorrectly. If the kernel debugger is connected and running when watchdog detects a timeout condition then DbgBreakPoint() will be called instead of KeBugCheckEx() and detailed message including bugcheck arguments will be printed to the debugger. This way we can identify an offending thread, set breakpoints in it, and hit go to return to the spinning code to debug it further. Because KeBugCheckEx() is not called the .bugcheck directive will not return bugcheck information in this case. The arguments are already printed out to the kernel debugger. You can also retrieve them from a global variable via "dd watchdog!g_WdBugCheckData l5" (use dq on NT64). On MP machines it is possible to hit a timeout when the spinning thread is interrupted by hardware interrupt and ISR or DPC routine is running at the time of the bugcheck (this is because the timeout's work item can be delivered and handled on the second CPU and the same time). If this is the case you will have to look deeper at the offending thread's stack (e.g. using dds) to determine spinning code which caused the timeout to occur. Arguments: Arg1: 824fd6a0, Pointer to a stuck thread object. Do .thread then kb on it to find the hung location. Arg2: 82675ce0, Pointer to a DEFERRED_WATCHDOG object. Arg3: 8266bd48, Pointer to offending driver name. Arg4: 00000001, Number of times this error occurred. If a debugger is attached, this error is not always fatal -- see DESCRIPTION below.

 - PREfast: pragma prefast The PREfast documentation seems a bit lax on the usage of pragma prefast for inhibiting display of individual warnings. It only shows how to inhibit Compiler warning 4068, but does not show how to specify the PREfast warnings. How do I use it in my source code? Can I use the pragma statements to turn a warning off before and off after a call to a function or macro (like IoSetCompletionRoutine) that always generates a PREfast warning (314, in this case)? Thanks for the help, Dennis In case any PREfast developers view this, I suggest looking at Gimpel Lint for effective ways to inhibit warning messages. Tag: Where I can download DDK? Tag: 54598

 - How to use 2 USB mice independently and simultaneously? Hello Experts :-), I am writing a Windows XP fun-application and would like to use 2 INDEPENDENT USB mice SIMULTANEOUSLY as input devices. Therefore, I understant, I have to go below OS mouse events (below mouse driver) as they all appear as coming from a single mouse. So, I tried to go through reading a HID-based device as described in the DDK. But I cannot get any data from a HID-based mouse. The reason is that I cannot even open a file by CreateFile (cannot get the handle to the mouse) cause this returns an Invalid_Handle_Value. What I think happens is that OS open a file earlier (at installing the device) capturing the handle and that only one file handle can be open to a HID based device, so the OS is the only one to be able to readall the HID input reports. Am I right? Or is ther a way to get input from mouse at HID device level? I see some solutions if I cannot access HID mouse from HID driver level: 1. At Windows level if there is some differentiation possible to see from which mouse the particular event came. But I doubt whether it is possible. 2. There is some way to overtake a handle to HID from OS. Whether stealing at the moment the device is connecting and drivers are interconnecting, or after the device is already connected. Somehow. I do not have a clue ho to do this. Any tips guys? 3. There is a filter driver needed below HID driver (HID mini driver? USB driver?), from where the mouse reports could be stolen from OS, or maybe forked? Would like to hear your opinion on that issue, Any help? Example code? Kind regards, Zed Tag: Where I can download DDK? Tag: 54597

 - Strange exception, please help I'm having a problem that I hope you can help me solve. My code is throwing an AV in the startup code in a way I've never encountered before. The instruction that causes the AV is: 006472E0 832D907FAF0001 sub dword ptr [0x00AF7B90], 0x01 The exception is: Access violation at address 006472E0. Write of address 00CC7B90. 0xAF7B90 is a variable in my BSS segment. 0xCC7B90 is outside of my address space. The code is in the initialization section of a 3rd party component which is called from the startup code, well before any of my application code executes. What I don't understand is how the above instruction could cause a write to an address different from the specified address. It seems suspicious that the addresses differ only in the 2nd byte. Thinking that I might have a hardware problem, I've swapped the CPU and memory in my computer, but the problem persists. I don't have a spare motherboard to swap in. This problem comes and goes depending on the address of the above SUB instruction. If I comment out a single line in my code, the SUB instruction appears at address 0x6472CC rather than 0x6472E0, and the instruction executes properly, subtracting 1 from the DWORD at 0xAF7B90.

 - Packect Filters/Drivers Hello all Thax for the suggestions if any. The work is meant for Windows CE. Some of the questions are generic to all of Windows. Ethernet, WAN ============= Assumptions about NDIS hook filter driver: a. Ndis Hook driver resides between Tcpip.sys and Ndis.sys (in NT/2K ) b. Replace NDIS.SYS function pointers(addresses) with new hook function addresses. c. So NDIS.SYS calls these new functions and new ones can call the original functions etc. 1. Under windows CE is this Ndis hook driver possible? (I guess YES. but usually replacing the NDIS.SYS addresses etc. might cause system exceptions in CE. doen't it?). 2. If yes, then Ethernet is okay. Meaning, it sits between tcpip and Ndis 3. But for WAN cases in CE, TCP/IP talks to PPP(No Ethernet emulation like NT/2K). PPP is a NDIS protocol driver in CE. So how do you hook this driver between these 2 protocols drivers? 3. If its not possible, Does a TDI driver type work in WAN case? Bluetooth ========= In case of bluetooth, different profiles use different stack paths( at least in CE ) Examples 1. A Serial port application goes thru RFCOMM to L2CAP 2. PAN NDIS driver goes to L2CAP directly. (I think TCP/IP talks to PNDIS). 3. LAN access profile goes thru TCP/UDP --> IP --> PPP ---> RFCOMM ---> L2CAP. How would one control bluetooth activities? a. Since more than 90% of the data flow goes thru L2CAP(rare cases hit HCI directly), Is there a way to develop a driver just above L2CAP and analyze the packets? Of course this may not be the useful place for encrypted packets, but we can control some. b. HCI Stack Extension Layer could be a solution?. If we develop one of this over L2CAP, could we selectively block the traffic? c. Any kind of hooking filter or TDI driver is helpful for this traffic? Thanks for the help and suggestions.

 - 16 Bit PC Card and resource problem Hi, This issue might have already answered many times on this post. On some laptops I cannot install the PC Card and as per the initial investigation looks like to me no memory available to address by 24 bits. I have tried modifying the inf to specify (D) for MemConfig and that maps the device on the higher address range addressable by 32 bit and gets installed properly but since it is a multifunction card I cannot get the functional device working, I get error 10. Once I specify (D) do I need to do anything else so that system and PC Card controller will be able to map the addresses properly? As well as is there any other workaround? - SK Tag: Where I can download DDK? Tag: 54575

 - Passing a Synthetic Write to a lower level Filter driver Hi folks, I am fairly new to the WDM Driver world. I have written a lower filter driver to view some serial port traffic,and now I want to be able to write to the driver my data - vs just passing down data from upper filter drivers. I got that working using iobuildasynfsdrequest with the MJ_WRITE ,and the lower Serial.sys driver responds with the correct response too. However - here's the problem - if any other application,eg hyperterminal has this port open,then that app also gets the writes from my driver. I tried queueing the IRPs from the above filters too-that did not work. So my question is this:how do I prevent my writes being "read" by other upper filter drivers? Have I layered my driver wrong? Any help appreciated.Thanks in Advance Jack Tag: Where I can download DDK? Tag: 54573

 - dispatch and completion routine in filter Hello, I wrote a dispatch routine for MJ_WRITE which splits the Systembuffer (IRP) into several characters and creates a new IRP for each. When I return STATUS_SUCCESS in the completion routine the pc reboots immediately without showing a blue screen. Returning STATUS_MORE_PROCESSING_REQUIRED and sending only one character to the filter is leading to a closed loop output of the incoming char. But there is no following blue screen or reboot. Perhaps somebody can help me.... thanks, Jürgen my dispatch routine: NTSTATUS DispatchWrite(IN PDEVICE_OBJECT fido, IN PIRP Irp) { PDEVICE_EXTENSION pdx = (PDEVICE_EXTENSION) fido->DeviceExtension; PIO_STACK_LOCATION stack = IoGetCurrentIrpStackLocation(Irp); NTSTATUS status; status = IoAcquireRemoveLock(&pdx->RemoveLock, Irp); if (!NT_SUCCESS(status)) return CompleteRequest(Irp, status, 0); pdx->buffer = (PUCHAR) Irp->AssociatedIrp.SystemBuffer; pdx->nbytes = stack->Parameters.Write.Length; NTSTATUS status2 = STATUS_SUCCESS; PIRP pNewIrp; PIO_STACK_LOCATION pStack; PVOID pbFakeWrite; for(int i=0;i < pdx->nbytes; i++) { status2 = STATUS_SUCCESS; pNewIrp = NULL; pNewIrp = IoAllocateIrp(pdx->LowerDeviceObject->StackSize, false); if (pNewIrp) { pbFakeWrite = ExAllocatePool( NonPagedPool, 1); RtlCopyMemory(pbFakeWrite, &pdx->buffer[i], 1); pStack = IoGetNextIrpStackLocation(pNewIrp); pStack->MajorFunction = IRP_MJ_WRITE; pStack->DeviceObject = pdx->LowerDeviceObject ; pStack->Parameters.Write.Length = 1; pNewIrp->AssociatedIrp.SystemBuffer = pbFakeWrite; IoSetCompletionRoutine(pNewIrp, (PIO_COMPLETION_ROUTINE)CompletionRoutine, pdx, TRUE, TRUE, TRUE); status2 = IoCallDriver(pdx->LowerDeviceObject, pNewIrp); IoReleaseRemoveLock(&pdx->RemoveLock, Irp); } } CompleteRequest(Irp, status, 0); return status; } ################################### my completion routine: NTSTATUS CompletionRoutine(PDEVICE_OBJECT DeviceObject, PIRP Irp, PVOID Context) { if (Irp->PendingReturned) IoMarkIrpPending(Irp); IoReleaseRemoveLock(&((PDEVICE_EXTENSION)Context)->RemoveLock, Irp); return STATUS_SUCCESS; } Tag: Where I can download DDK?

 - 1394 Surpise Removal I have a two 1394 cameras setup and I run into an error which causes my application to never exit the task manager. The application goes through the entire shutdown process (even the destructor of the main frame) but the process seems to still be running. I cannot kill the process but it eventually dies (~10 minutes or so). Disconnecting both devices at the same time while the application is running causes the following behavior: 1) WM_DEVICE change leads to a getDeviceList (using the setup api). 2) Setup API returns 1 device present which is technically not correct. 3) My app tries to do a REQUEST_ASYNC_READ to determine if the device is valid. 4) This 1394 driver fails the submit to lower device with an error of NO SUCH DEVICE. 5) Because I did this read, the application does not shutdown properly. Does anyone have any ideas for things that I can look at? Thanks in advance, Mukul Tag: Where I can download DDK? Tag: 54561

First it compiles without error, but when i try to use "InterlockedExchange" in the cancel example i have the same error as for my driver. So any suggestions how to avoid this error, is there maybe a newer version of csq.lib for W2K? Thanx for your help, Jens Salewski Tag: Where I can download DDK? Tag: 54555

 - Using DocumentEvent from OEMUI plugin I am trying to catch the DocumentEvent event in a unidrv UI plugin. I used the sample code in the DDK and changed the IPrintOemUI to IPrintOemUI2. I then added the follwing to interface.h: STDMETHOD (DocumentEvent) (THIS_ HANDLE hPrinter, HDC hdc, INT iEsc, ULONG cbIn, PVOID pvIn, ULONG cbOut, PVOID pvOut, PINT piResult); STDMETHOD (HideStandardUI) (THIS_ DWORD dwMode) ; STDMETHOD (QueryJobAttributes) (THIS_ HANDLE hPrinter, PDEVMODE pDevmode, DWORD dwLevel, LPBYTE lpAttributeInfo) ; I then implemented the functions in interface.cpp such that each of the new methods would display a MessageBox when invoked. The problem is I don't get any MessageBoxes displayed. I put a MessageBox in GetInfo() as well and that gets displayed so I know the correct plugin is loaded. Is there something else I need to configure to get IPrintOemUI2 methods to be invoked? Thanks, Bob Tag: Where I can download DDK? Tag: 54508

 - A doubt on handling IRP's I am writing a storage filter driver and need to keep track of all read/write requests. So for every device (volume) that I monitor, I have a small cache in the device object (in device extension). As soon as a read/write request comes in, I add this info to this cache. I need to synchronize access to this cache. So I have a mutex (wont work on multiprocessor but this is just a demo) which guards the code that manipulates the cache. All this is working fine but I am kind of doubtful about this access to the cache. Since I am adding this synchronization object to keep track of the IRP's, I am kind of slowing down the behavior because of the synchronized access to the cache. Every Read/Write request will have to wait to access this cache. So I am kind of skeptical about this design. Is there a better way to do this? I feel that the IRP's being "tunnelled" thru will affect overall performance. Thanks, Gary. Tag: Where I can download DDK? Tag: 54503

 - OpenHCI bug on Win2k? "Alexander Grigoriev" <alegr@earthlink.net> wrote in message news:u0bmWZivEHA.3320@TK2MSFTNGP14.phx.gbl... > Can you post code where you initialize URB and IRP? > The code to init IRP and URB are given below. I am wondering if OpenHCI will handle data buffers bigger than the max packet size on the pipes. It appears that it also does not like the buffer (512 bytes) I pass to the interrupt pipe (with max packet size of 8 bytes).

I am wondering if OpenHCI will handle data buffers bigger than the max packet size on the pipes. It appears that it also does not like the buffer (512 bytes) I pass to the interrupt pipe (with max packet size of 8 bytes). The usbport.sys, which my driver calls on XP, handles bigger buffers just fine. Now MS document on UsbBuildInterruptOrBulkTransferRequest does not put size limit on the data buffer used.

 - Detect video rotation Many recent notebook computers have added various features to rotate the display either to switch between portrait and landscape, or to rotate 180 degrees (usually, the argument for this is that in Japan, they like to sit across the table from their customers and flip the display so that it's face up to the customer but upside down to them). Detecting the difference between portrait and landscape mode generically is pretty easy (if nothing else, you can look for a WM_DISPLAYCHANGE message and see whether X or Y is bigger). However, I haven't (in a very short amount of searching so far) figured out any way to generally (i.e. not dependent on video driver) detect a 180 degree rotation. Does anyone here know whether there is a general way to detect this? -- ../ray\.. Tag: Where I can download DDK? Tag: 54484

 - Modem traffic monitoring Hello, All. I am writing a driver that should be able to monitor traffic going through the modems (internal or external). And I should be able to forbid any undesired dialing calls (by seeking for ATD string). Any other traffic analysing can be required in future. I can write Modem class filter driver. But in such case the user can dial through COMx port. So it seems that I have to write Serial Port device filter diver. But the user can install hardware after my driver installation. So new ports can be added, and my driver will not filter their activity. How this problem can be avoided? And may be some more elegant solution exists? Thank you for your attention.

 - installing driver "FROM" a Service during startup Calling OpenSCManager() to install a driver from a service that is automatially starting during system start appears to "block" after the SCM has determined that the Service has hung. Why is this? What can I do to install a driver at service * system start time. DETAILS: I have a service that is automatically started on system startup. During service start it installs and creates a driver. This works fine starting and stopping the driver using the MCC Service manager. However, it "blocks" during system startup but does load successfully -- placing a number of eventlog entries in the Service I see: Service starting (time x) Service ready to call OpenSCManager() to load driver (time x+1 second) SCM reporting Service "Hung" (time x+10 seconds) Service finishes call to OpenSCManager() and successfully loads driver (time x + 11seconds to 1 minute!!!) Service started When starting under MCC Service manager it starts in a second or two. Under system start the Service components all start very quickly, except the call to OpenSCManager does not complete until the SCM loading the Service declares the Service Hung. What gives?

 - Interesting driver modification in win2k I'm looking for someone who can do a simple mouse driver modification for w2k using the existing driver code in w2k DKK. The goal of this assignment is to replace current mouse acceleration algorithm with an advanced one to improve mouse precision and smoothness in all applications, including games. This new algorithm calculates mouse acceleration dynamically as opposed to fixed value threshold algorithm that windows use. The technical side of this is not too hard and I was told it won't take more then an hour for an experienced driver developer to do. Should be an interesting assignment however,and I am ready to pay you a small fee for your effort, let's say 20$. That's a decent hourly pay I think :).

 - Kernel Streaming and WAVE_FORMAT_EXTENSIBLE Hi folks, Been debugging an audio playout minidriver (under stream.sys), and slightly surprised about what I'm getting for data formats. Put simply, I have a 20 bit PCM audio stream, which I want to play out via the driver. I *expected* that when it came to opening the stream, I'd have something like this: For the sake of brevity: "pSrb->CommandData.OpenFormat" = "Format" from now on. I expected Format.DataFormat.MajorFormat = KSDATAFORMAT_TYPE_AUDIO Format.DataFormat.SubFormat = KSDATAFORMAT_SUBTYPE_PCM Format.DataFormat.Specifier = KSDATAFORMAT_SPECIFIER_WAVEFORMATEX And indeed, I get all those things. Then, for the 20 bit audio file I was testing, I was expecting (Format is cast to PKSDATAFORMAT_WAVEFORMATEX) Format.WaveFormatEx.wFormatTag = WAVE_FORMAT_EXTENSIBLE Format.WaveFormatEx.nChannels = 2 Format.WaveFormatEx.nBlockAlign = (probably 6, but further data in extensible). Format.WaveFormatEx.wBitsPerSample = 24 Format.WaveFormatEx.cbSize = //extra size needed Specifically, I expected wBitsPerSample to describe the sample container size, and further information to be in the extensible structure, something like this (off the top of my head): Extensible.wValidBitsPerSample = 20 //contrasting with 24 above. Extensible.dwChannelMask = MASK_STEREO //or equiv. Extensible.SubFormat = FORMAT_SUBTYPE_PCM. Unfortunately, it doesn't work like this. I am fairly sure that the filter I'm connecting to is usign WAVE_FORMAT_EXTENSIBLE, but it seems like KsProxy is ditching it. This then means that I get something like this: Format.WaveFormatEx.wFormatTag = WAVE_FORMAT_EXTENSIBLE Format.WaveFormatEx.nChannels = 2 Format.WaveFormatEx.nBlockAlign = 6 Format.WaveFormatEx.wBitsPerSample = 20 Format.WaveFormatEx.cbSize = 0 This is a big problem for me because it then means that I'm potentially vulnerable to alignment / location / channel issues. For the moment, I can *assume* from the block align and the number of channels the actual sample container size, however, it's not exactly a very nice solution, and once I have more than 2 channels, I now have the issue that because there's no channel mask, I don't know which channels are which :-( Does KsProxy always ditch the extensible data? Is this the best that one can do running under stream.sys? MH. Tag: Where I can download DDK? Tag: 54459

 - problem installing hardware device I have a problem when I try to install a new hardware device. Maybe this is not the right group to post this question, but I'm sure that someone here can help me. - This problem occurs when I try to install a new hardware device. I have the same problem with 2 different devices from 2 different vendors (a PCMCIA wifi card, and a USB wifi device). - I've installed the software coming with these devices. I also tried with the latest version I downloaded from internet. - When I plug in the device, the 'found new hardware' wizard starts up. After a few seconds, I get the error message 'An error occurred during the installation of the device'. The system cannot find the file specified'. I think the missing file is a system file (not a driver file), but I don't know which one. - When I click then 'Finish' (the only possible choice), the wizard stops and restarts immediately. - I also trieed to add the hardware from the device manager, with the same result. - Below, I add the logging from setupapi.log (after increasing the logging level). I hope someone can help me out. ========================================== [2004/10/31 21:31:52 584.2]: Loading class-installer module for IEEE 802.11g Wireless LAN USB Card.

Just a moment - don't jump on me please...

The "which DDK" page
http://www.microsoft.com/whdc/driver/foundation/WhichDDK.mspx
says that SP1 beta DDK available to MSDN subscribers, but it doesn't seem to
be in subscriber downloads.

Looking now under Universal downloads, Platform Tools, SDKs,DDKs/ Windows
server 2003 - and there is only one DDK, Server 2003, ver. 3790.

SO, how MSDN subscribers are supposed to get Server 2003 SP1 beta DDK?

Regards,
Pavel

Thanks, you're correct, as always...

in case somebody else has bad eyes day too, the ddk is under:
Platforms - Windows server2003 - Windows server2003 Prerelease/beta -
x64 Edition systems -or- Itanium-based systems
