Yes, that is what I expected after thinking long enough to realize that I could just read this out of the usbmon dump you provided. Thanks a lot for all your help providing extremely useful debug info here. This helped fixing (soon, anyway :-) a nasty bug, hitting only a few devices. I still don't know for sure, but I do hope this bug is the real cause of the problems you are having. I'll send you a patch for testing as soon as it is ready.
