     19 This test uses servo to connect/disconnect servo USB hub before and
     20 after events like reboot, login, suspend, resume etc.
     21 
     22 The test fails if
     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
     27 - USB peripherals checks(usb_checks below) on command line fail
     28 Other detection checks can be added for each peripheral
     29 
     30 Set of four USB peripherals plugged
     31 - USB headset
     32 - USB HD Webcam - should be Logitech HD Pro Webcam C920
     33 - USB stick with four partitions named ExFAT  Ext4  FAT  NTFS
