IOCTL_HID_WRITE_REPORT fails
in [Device Drivers]
|
From: tatsun on 30 Nov 2009 21:40 Hi I am developing the driver based on HidFx2Usb driver source. Application call WriteFile() then driver called IOCTL_HID_WRITE_REPORT. So I add the following code in this IOCTL process in order to send data to the USB, but CompleteWriteReport callback routine always called with status = STATUS_INVALID_PARAMETER (0xc000000d). I do not know why error occurs. --- code --- status = WdfRequestRetrieveInputMemory(Request, &memory); if (!NT_SUCCESS(status)) { goto Exit; } status = WdfUsbTargetPipeFormatRequestForWrite( pipe, Request, memory, NULL ); if (!NT_SUCCESS(status)) { goto Exit; } WdfRequestSetCompletionRoutine( Request, CompleteWriteReport, pipe ); if (WdfRequestSend( Request, WdfUsbTargetPipeGetIoTarget(pipe), WDF_NO_SEND_OPTIONS ) == FALSE) { status = WdfRequestGetStatus(Request); goto Exit; }

From: tatsun on 4 Dec 2009 00:12 Thank you Doron I retrieved the WDFMEMORY from WDFREQUEST as follows, status = WdfRequestRetrieveInputMemory(Request, &memory); status is OK, but memory object does not contain buffer information. Because I added below code and check return value, buffer=NULL. buffer = WdfMemoryGetBuffer(memory, NULL); I checked MdlAddress and found the data is stored in MDL. So I retrieved the buffer and its length successfuly as follows, Irp = WdfRequestWdmGetIrp(Request); Buffer = (PUCHAR)MmGetSystemAddressForMdlSafe(Irp->MdlAddress, NormalPagePriority); BuffLen = Irp->MdlAddress->ByteCount; After above I add making the new WDFMEMORY object and called WdfUsbTargetPipeFormatRequestForWrite, then called WdfRequestSend, it success. Is my method OK ? Thanks.

From: Doron Holan [MSFT] on 4 Dec 2009 13:10 for IOCTL_HID_WRITE_REPORT, the KMDF APIs used to extract the buffer do not work b/c hidclass does not follow the standard rules for formatting. you get the buffer from Irp->UserBuffer which is a pointer to a HID_XFER_PACKET. the HID_XFER_PACKET contains pointers for the underlying buffer and its length d -- This posting is provided "AS IS" with no warranties, and confers no rights.
