Hans, it seems to me that there is a problem. uas_pre_reset() calls flush_work(). uas_do_work(), however can reschedule itself if usb_submit_urb() fails. That opens up the possibility that there's a permanent problem with the device which causes an attempt to reset it and makes usb_submit_urb() fail. What do you think?
