Jan Axelson:
To isolate the problem, use a protocol analyzer or whatever debugging tools you have to find out how the device is responding to the transaction attempts.

 everything it should be work?

i need test winusb function's for my engineering thesis, and i need device i can do this board.

Jan Axelson:
I'm not familiar with that board specifically, but my firmware is for the 18F4550, and I've heard from folks who have used the firmware with my WinUSB host application on a variety of boards.
