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#
