Thanks for the log. I can see in it exactly what you're reporting.
Unfortunately, there isn't enough information in it for me to spot (at least
yet) what went wrong. I've attached a patch (usb1.patch) to this message. Are
you familiar with how to apply it and then generate a new log? Also, when
generating the new log, please add async to the -l keyword list.
