This test initially checks the number of USB devices connected to CFM.
Verify Hotrod can detect speaker, mic and camera. If not, test is aborted.
After that the test will run number of loops where it does:
1. Join a hangout session
2. leave hangout session
3. Check number of USBPeripheral devices and compare it to the initial ones. If
   difference is detected test will report failure.
4. Repeat 1, 2 and 3 for random times
4. Reboot CfM
