    - KSMETHOD_TYPE_SOURCE: what it actually means I am trying to implement KSMETHOD on the AVStream mini-driver we developed. I would like to implement an asynchronous handling of the IRP passed into the methodhandler where data will be filled by the device into the output buffer through DMA (data will be in the order of megabytes). For this I believe that the output buffer should be directly passed into the driver, i.e. MDL for output buffer should be created with probe and lock. After going through KSMETHOD_ITEM>Flags member documentation I think it is done by the class driver but could not make out how to specify what I want. The confusion arise because of the way KSMETHOD_TYPE_SOURCE macro is explained. Whether setting it will lead to buffering? if so how source mode can then be enabled and when will the data be probed and locked? Hope someone has clarity on this. Thanks In Advance.

    - communication between wdf and wdm drivers. Hi, i have an architecture question regarding communication between a wdm driver and a wdf driver. my system holds an old wdm driver and a new WDF based driver. My product is going through a phase where these two drivers will need to communicate (until the old wdm will not be used anymore). i read some of your articles regarding driver-to-driver communication and i basically use function pointers (and interface notification for synch) and all works well. i started to face a problem when i try to do as follows : my WDF driver will be called with a pending IOCTl in order to fill some data and return it to the user mode part of that WDF driver. My WDM driver, however, is the one who's responsible for the interrupt handling. so - when an interrupt arrives, the WDM driver handles it and in its DPC will use function pointers in order to call a routine that is implemented in the WDF driver. here's where the problem starts : since the call comes from the WDM driver context i'm not able to use in that function any WDF calls. i get bug check. so my question is how would i be able to complete the pending IOCTL request in the WDF driver from a call in the WDM driver since i'm not able to use any WDF methods such as WdfCompleteRequest. does it seem right to use a work item in the WDF driver that would be signaled when the WDM driver uses the function pointer (a function that is implemented in the WDF driver which passed the function's pointer to the WDM driver) ? thanks, Kobi.

    - I/O target from socket doesn't timeout Hi, I have created an I/O target from a socket but when I send an I/O request to it, it won't timeout. The socket was created with WSASocket passing WSA_FLAG_OVERLAPPED and I used setsockopt() to set read/write timeout as below.

    - I need a network miniredirector sample, NulMRx DDK sample doesn't Hi, I downloaded WDK 6001.18001. I built NullMRx sample and installed it. I tried it on WinXP and W2K3.. Unfortunatelly "net use * \\nulsvr\share" does not work. It returns with "System error 67 has occurred. The network name cannot be found." In init.c (Line 284) RxStartMinirdr function failed. It returns with "c000000e" (STATUS_NO_SUCH_DEVICE). I found this in the MSDN: "The call to RxStartMinirdr cannot be made from the DriverEntry routine of the network mini-redirector after a successful call to RxRegisterMinirdr since some of the start processing requires that the driver initialization be completed." But the RxStartMinirdr is called from DriverEntry. Could someone help me to solve this problem or give me a sample which works. Would be very important. Thanks, Misi. Tag: test only Tag: 107482

    - DirectInput, USB HID filters, and EvtInternalDeviceControl I'm trying to write a filter for a USB HID device that will essentially override the device's HID Descriptors with a custom version, but otherwise function as a normal HID device. I've gotten the driver to compile, install, and execute but the EvtInternalDeviceControl function is never called. I've checked several of the KMDF samples and it appears I'm registering the function correctly. My EvtDeviceAdd and EvtDeviceD0Entry functions run, but nothing after. Further, will I need to do anything special in order to have DirectInput correctly recognize the device with the corrected descriptor? I'm using the hidkmdf HID minidriver KMDF sample as the function driver with this as my LowerFilter. I can post additional code and log data as needed. Below is the pertinent piece of my DeviceAdd function: WDF_IO_QUEUE_CONFIG queueConfig; WDFDEVICE hDevice; /* SNIP */ status = WdfDeviceCreate(&DeviceInit, &attributes, &hDevice); if (!NT_SUCCESS(status)) { DbgPrint("SIXCD: WdfDeviceCreate failed with status code 0x%x \n", status); return status; } WDF_IO_QUEUE_CONFIG_INIT_DEFAULT_QUEUE(&queueConfig, WdfIoQueueDispatchParallel); queueConfig.EvtIoInternalDeviceControl = SixcdEvtInternalDeviceControl; status = WdfIoQueueCreate(hDevice, &queueConfig, WDF_NO_OBJECT_ATTRIBUTES, WDF_NO_HANDLE ); if (!NT_SUCCESS (status)) { DbgPrint("SIXCD: WdfIoQueueCreate failed 0x%x\n", status); return status; } Tag: test only Tag: 107462

    - XcvData broken on Vista I have a print driver/port monitor pair that use XcvData and XcvDataPort to communicate. When the printer is being used as a network printer and connected to by a client, the driver on the client calls XcvData with a custom string in pszDataName. My XcvDataPort function in the port monitor recognizes this string and responds with the requested data. It's very simple, fully supported according to the documentation, and works flawlessly between XP boxes. But throw Vista into the mix and it's completely broken. If the server is XP and the client is Vista, XcvData returns error 2 (file not found). The port monitor on the server is *not* called. Conversely, if the server is Vista and the client is XP, XcvData returns error 122 (insufficient buffer). And again, the port monitor on the server is not called. However, despite the fact that XcvDataPort was never called, XcvData gives me back error 2 as XcvDataPort's return code. The actual printing works flawlessly in both cases, so I know it's not a fundamental permissions or network issue. It's purely a problem with XcvData. I strongly suspect it's a security issue since most things Vista are, but even if I turn off the firewall, UAC, print as admin, set permissions on the printer to full control for everyone, etc, I get the same results. It's as if Vista is simply refusing to allow XcvData to communicate with the port monitor. Any clues? Simplified code follows to give you an idea.... On the client I do this: // open the port on the print server HANDLE hServer; if (!OpenPrinterW(L"MyServer\\,XcvPort DIRPS:", &hServer, NULL)) return false; // request the data char *pBuff = new char[dataSize]; if (!XcvData(hServer, L"GetConfigData", 0, 0, (PBYTE)pBuff, dataSize, &dataSize, &status) || status != ERROR_SUCCESS) return false; On the server, the port monitor does this: DWORD WINAPI XcvDataPort(HANDLE hXcv, LPCWSTR pszDataName, PBYTE pInputData, DWORD cbInputData, PBYTE pOutputData, DWORD cbOutputData, PDWORD pcbOutputNeeded) { if (pszDataName && !wcscmp(pszDataName, L"GetConfigData")) { *pcbOutputNeeded = dataSize; if (cbOutputData < dataSize) return ERROR_INSUFFICIENT_BUFFER; *pOutputData = myData; return ERROR_SUCCESS; } return ERROR_SUCCESS; } Tag: test only Tag: 107448

    - Microsoft RNDIS driver failed to handle multi config descriptors Does Microsoft Window (XP Host) RNDIS driver support multiple configuration descriptors? We changed the WinCE RNDIS driver code to provide two configuration descriptors to the host. When we pass the 2 configuration descriptors per the USB specification the host(XP) accepts them by returning a "SetConfiguration" message with a valid configurationValue, and then subsequently dies with an error 10.

    - Checked build driver with free build OS.... Hi, I know, to help debugging, its required to have the windows checked build and with checked build driver (driver under development). But what happens if checked build driver is loaded and used with free build os ? (XP SP2). As far as I know, the checked build driver 1. Does not have optimization enabled 2. Lots of DbgPrint 3. The size of the binary is huge (because of symbols and etc). 3. The driver will be slow. Are there anything more to add to the above list ? If I manage to remove all the prints and if the driver is meeting the performance criterion, is it advisable to deploy the checked build driver with free build OS ?

    - Port Monitor: referencing external libraries in sample code Hi, I am new to Driver development. I am implementing the Port monitor for our printer driver. Basically I am migrating from a previous Port Monitor( visual studio project) which implements the MONITOR structure to the recent MONITOR2 structure using the DDK environment. As can be seen, there is some similarity in the MONITOR2 and MONITOR structure and some of the existing functionality can be reused. So I planned to export the functions required by MONITOR2 from the current port monitor library and use it in the DDK sample port monitor(ddklocalmon). For this I implemented the header file for the existing Port monitor and compiled it as a static library. Added the function names to the .DEF file. I included this library in the TARGETLIBS section of the Sources file in localmon directory. Also added the path to the header file in the INCLUDES section. However when I added a call to the logerror() function in the imported library, I get the following error on linking Linking Executable - objchk_wxp_x86\i386\ddklocalmon.dll errors in directory d:\doccreator\actino\p4root\jaws\niknak\win\localmon d:\doccreator\actino\p4root\jaws\niknak\win\localmon\localmon.obj : error LNK2019: unresolved external symbol _logerror@0 referenced in function _LcmStartDocPort@20 d:\doccreator\actino\p4root\jaws\niknak\win\localmon\objchk_wxp_x86\i386\ddklocalmon.dll : error LNK1120: 1 unresolved externals Questions: 1] Can someone please let me know what could have gone wrong with this implementation.? 2] Is adding a reference to a Visual studio library to the DDK project possible? 3] Have I added the library and header file to the correct sections in the Sources file? Please let me know if you need more explaination. thanks Mangesh Tag: test only Tag: 107425

    - Can more than 3 packets be transfered per microframe in iso? For ISO transfer, we need to send 4 of 1024 per microframe for speed needed. The protocol says that bit12-11 define the number of packets per microframe. And it can only be as many as =92b10 for 3 packets per microframe. However, in USB 2.0 spec Table 5-5 =91High-speed Isochronous Transaction Limits=92, it clearly shows that packets per microframe can be more than 3. (e.g., for 1024 bytes packet, it can be 7 ; for 64bytes packet there can even be 73 packets per microframe). Thanks Tag: test only Tag: 107416

    - Regarding "bTemporalCompression" in avshws of DDK Hello, I am developing a PCI capture driver, and I use "avshws" as sample to develp the driver. I can capture AVI with H.264 codec by AMCAP, and the avi file can play well. My problem is as following: I would like to set bTemporalCompression(in KS_DATARANGE_VIDEO) to be TRUE. Then, the captured AVI frames will be not all marked as key frame. I connect capture pin to dump filter. When I trace in avshws, bTemporalCompression is really true. But when I trace into dump filter, it shows bTemporalCompression as FALSE. In addition, in "IntersectHandler" function, the sample code doesn't copy "bTemporalCompression" and "bFixedSizeSamples" into "Data"(PKS_DATAFORMAT_VIDEOINFOHEADER). If I write following code: FormatVideoInfoHeader->DataFormat.SampleSize = 0; Then, I can see "bFixedSizeSamples" in "Dump" filter is updated to FALSE. Therefore, should I copy "bTemporalCompression" into somewhere to make the flag enable? Can somebody kindly help me to solve this problem? My data range defines as following: KS_DATARANGE_VIDEO FormatH264_Capture = { // // KSDATARANGE // { sizeof (KS_DATARANGE_VIDEO), // FormatSize 0, // Flags DMAX_X * DMAX_Y * 2, // SampleSize 0, // Reserved STATICGUIDOF (KSDATAFORMAT_TYPE_VIDEO), // aka.
