     19 This test uses servo to connect USB devices.
     20 This test verifies if drivers are created for each USB device or not.
     21 
     22 The test fails if
     23 - if USB device is not detected in lsusb command
     24 - if driver for USB device is not created
     25 - USB detected peripherals are different than expected
     26 - there is no servo board attached

     28 Set1 is set of four USB peripherals plugged
     29 - LG Android phone
