The Mark's description sounds like a bug but I think may be confused. The usb-uhci was not changed. > IMHO the returning of usb_submit_urb() should (and is, AFAICS) a clear > barrier indicating whether the completion handler will get called or not. Absolutely. Better say "The return code of usb_submit_urb() indicates if the callback was or will be called". If error is returned, no callback was or will be called for the URB. The past tense is for root hub and other imitation devices that deliver callbacks from inside of usb_submit_urb(). -- Pete _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
