I think I've solved this problem. The driver wasn't checking the
active flag on TDs in check_td_list(). If the c67x00 ran out of time
in a frame, not all the TDs would get processed. Without this check
the HCD would interpret unprocessed TDs as successfully completed.
I've also got a fair number of comments/changes on the driver in patch
form. I'll send it to the list shortly.
Cheers,
