20This test uses servo to connect/disconnect servo USB hub before and
21after events like reboot, login, suspend, resume etc.

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