Bug Description
I noticed that my Nexus 4 crashed while doing a
grep "1" -r /
in an adb shell as user phablet. After narrowing it down, it looks like I can reliably crash my device by just doing a
cat /sys/devices/
as a normal user. After doing it about three times, all aspects of the device still work as expected, but it no longer identifies itself via USB, not even when in recovery mode. This might be a different issue, but it has never happened before, so I do think it might have been caused by the crashes.

The USB port luckily came back to life after fully draining the battery.
