# [PATCH] synchronous control/bulk messaging
#
# This one-liner fixes a problem in synchronous messaging
# with usb_bulk_msg(), usb_control_msg(), and everything
# that calls usb_control_msg(): you're not allowed to call
# blocking functions when you're already on a wait queue.
#
# A better fix would be to just stick the thread on the
# wait queue _after_ submitting the URB, but that should
# involve more testing than I have time for just now.
