Hi Julian, You might like to refer to this thread: http://www.avrfreaks.net/index.php?name=PNphpBB2&file=printview&t=88432&start=20 As I have found out, it is not necessary to have the same EP number for IN and OUT for rate feedback to work with a Linux or OSX host. This may be a requirement for Vista/Win7 hosts though. We are still doing testing.
