Anyone has a guess? I am going to start to read the Atmel docs now.

I don't have time to debug this issue, but a USB Analyzer trace clearly shows that the SET ADDRESS command goes wrong.

My guess: The only difference between the Windows and MacOS X trace is a USB Reset between the GET DESCRIPTOR and SET ADDRESS command on Windows, the Reset is not there on MacOS X (don't know what Linux does). So I would look if "upcd.state" is USB_STATE_DEFAULT, if not STD_SET_ADDRESS won't do anything. From my understanding "upcd.state" is set to USB_STATE_DEFAULT on a USB Reset, so it might not be initialized properly.
