I've been seeing this a lot on build49-b1. Ben, is there anything we could look at on the bot itself to find out if something's wrong with the bot that's causing devices to drop offline?

Any examples of recent failures? (within past couple days)

There's a couple of places to look. For something like DeviceUnreachableError, I find that it's usually due to the device constantly disconnecting/reconnecting to the host. I'd grep through /var/log/syslog to see how often the specific device shows up. If it's several times a minute, that's usually due to failing hardware (cables, hub, bus, etc.)

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available.
