IOCTL_HID_WRITE_REPORT fails

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;
}

WdfUsbTargetPipeFormatRequestForWrite does not send a
IOCTL_HID_WRITE_REPORT. you need to format the pipe for an IOCTL

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.

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
