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

Set1 is set of four USB peripherals plugged
- LG Android phone
- USB 3G dongle
- USB HD Webcam - should be Logitech HD Pro Webcam C920
- USB3.0 Card Reader
- USB Headphone
- USB Mouse
