   4#
   5# - control: any device can do this
   6# - out, in:  out needs 'bulk sink' firmware, in needs 'bulk src'
   7# - iso-out, iso-in:  out needs 'iso sink' firmware, in needs 'iso src'
   8# - halt: needs bulk sink+src, tests halt set/clear from host
   9# - unlink: needs bulk sink and/or src, test HCD unlink processing
  10# - loop: needs firmware that will buffer N transfers
  11#
  12# run it for hours, days, weeks.
