EventWriteReadStart(&activity, WdfIoQueueGetDevice(Queue), (ULONG)Length);
EventWriteReadFail(&activity, WdfIoQueueGetDevice(Queue), status);
EventWriteReadStop(&activity,
WdfIoQueueGetDevice(WdfRequestGetIoQueue(Request)),
bytesRead,
status,
usbCompletionParams->UsbdStatus);

I can not find the function prototype in wdk or msdn.
what’s the function purpose?

The definitions for KMDF functions appear in WDF.H (as opposed to WDM.H)… is that what you’re asking?? If you look at the bottom of the MSDN doc page on WdfRequestSend (for example) it tells you which file to include.

If that’s not your question, can you try to explain a bit more about your problem?
