20This test uses servo to connect/disconnect servo USB hub before and
21after events like reboot, login, suspend, resume etc.
22
23The 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
29Other detection checks can be added for each peripheral
30
31Set1 is set of four USB peripherals plugged
32- USB headset
33- USB HD Webcam - should be Logitech HD Pro Webcam C920
34- USB stick with four partitions named ExFAT  Ext4  FAT  NTFS
