Full speed interrupt transfers work for me, but high speed do not. This is on 2.4.22 and 2.4.20-18.3 (a RedHat kernel). I am setting the URB interval and not resubmitting, just filling the transfer buffer with new data each time I get a callback. With high speed I get lots of messages like Sep 2 18:13:45 host kernel: ehci-sched.c: intr qh df9ff100 no TDs? Sep 2 18:14:16 host last message repeated 31530 times I have not had time to investigate. Below are logs for the host and gadget side showing first the drivers working at full speed behind a 1.1 hub, then failing at high speed when connected directly. This is 2.4.22 with CONFIG_USB_DEBUG and a few extra debugging messages I added in tracking down the interval conversion. The messages from uth and utg are from my drivers. If you see anything obvious here, I would appreciate hearing about it. Otherwise, I will debug further soon.
