I have a query on IRPs :- I want to know what exactly is an IRP from the programmers point of view and how the USB client s/w determines the type of transfer for the IRP and the transactions required for the IRP. Which part of the USB s/w exactly carries out the transfer of data if a data transfer is required to /from the device? Regards, Dattaram. _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: http://lists.sourceforge.net/lists/listinfo/linux-usb-devel
