     20 This test uses servo to connect/disconnect servo USB hub before and
     21 after events like reboot, login, closelid, openlid etc.
     22 
     23 The test fails if
     24 - device is pingable when suspended
     25 - wrong action passed through action_sequence flag
     26 - USB detected peripherals are different than expected
     27 - there is no servo board attached
     28 - USB peripherals checks(usb_checks below) on command line fail
     29 Other detection checks can be added for each peripheral
