Repeatedly power cycle the connected device and verify it appears
as a USB device after each cycle. Verifies that no new crash files
appear.
The test requires a vid_pid argument (e.g. 18d1:8001) that determines which
device to power cycle. This enables testing custom devices from Moblab or from
a local workstation.
In Moblab, add vid_pid=<vid:pid> under Advanced Options -> Args.
Locally, add arguments with --args when running test_that. Example:
test_that --autotest_dir ~/trunk/src/third_party/autotest/files/ \
--board=guado --args 'servo_host= vid_pid=18d1:8001' \
