I suppose this is device-specific and will have to be worked around in the driver buy resubmitting request a few times until it "sticks".Hmm, I take it back... the message comes from the IRQ routine; that means we were able to submit IRQ at least once. Plus we do send a few control messages for mtouch. So I don't understand why it would start returning -ENODEV out of sudden.
A usbmon trace might come in useful here. See the instructions in Documentation/usb/usbmon.txt. Alan Stern
