Ah, thanks. Any hints on where to find it? I tried adding his name to my archive/google searches but keep coming up with many unrelated posts... :-/ About all I've managed to do so far is to verify that it doesn't appear to be an interrupt routing problem. The driver is indeed receiving interrupts. However the status register only says that it's a root hub status change, never to advise that a transfer is complete :-( Polling mode doesn't seem to help as it queries the same register... It also sometimes interrupts with intrs==0 right after a transfer starts, which sounds bogus to me. I'm in single-user mode and positive that nothing else on irq 11 is interrupting. Oh well, for now I'm content to just keep hacking on it and learn more about how the code works :) Craig
