19This test uses servo to connect/disconnect servo USB hub before and
20after events like reboot, login, suspend, resume etc.
21
22The 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
28Other detection checks can be added for each peripheral
29
30Set 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
34- etc.
