This test uses servo to connect/disconnect servo USB hub before and
after events like reboot, login, suspend, resume etc.
The test fails if
- device is pingable when suspended
- wrong action passed through action_sequence flag
- USB detected peripherals are different than expected
- there is no servo board attached
- USB peripherals checks(usb_checks below) on command line fail
Other detection checks can be added for each peripheral
Set of four USB peripherals plugged
- USB headset
- USB HD Webcam - should be Logitech HD Pro Webcam C920
- USB stick with four partitions named ExFAT Ext4 FAT NTFS
- USB mouse
- USB 3G modem
- USB SD card reader(one microSD card plugged)
- USB connected phone(optional)
