This test uses servo to connect USB devices.
This test verifies if drivers are created for each USB device or not.

The test fails if
- if USB device is not detected in lsusb command
- if driver for USB device is not created
- USB detected peripherals are different than expected
- there is no servo board attached

USB peripherals plugged
- USB Epson XP-610 Series printer
