18This test uses servo to connect/disconnect servo USB hub before and
19after events like reboot, login, suspend, resume etc.

21The test fails if
22- crash files are generated
23- device is pingable when suspended
24- wrong action passed through action_sequence flag
25- USB detected peripherals are different than expected
26- there is no servo board attached
