Bug Description

Invoking run_itah_phablet.py when the USB adb connection is not plugged it causes the script to hang indefinitely:

sudo PYTHONPATH=./touch ./touch/examples/run_utah_phablet.py --skip-install -l /home/phablet/utah_tests_pm/pm_idle.run --results-dir /home/king/nexus-power/utah/results -d /home/king/nexus-power/utah/touch/disconnected.sh
= setting up network...
Network file is /etc/NetworkManager/system-connections/GLMLINUX
Provisioning network file to device
error: device not found

Although this is indeed a mistake by the user, there is a "error: device not found" error that is reported, so perhaps this error can be detected and the script exits rather than waiting forever.
