# USB fix documentation bug
# 
#  After some source investigations I discovered a harmless mistake:
#  The description of the  usb_control_msg(...) function says
#  it returns 0, or less than 0 if an error occured, but
#  the usb_internal_control_msg returns length, which is sometimes >0
#  (success) or <0 if error.
