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