Usb exception keeps taking swarming android bots offline

Project Member Reported by bpastene@chromium.org, Dec 16 2016

Issue description

Just had to bring back over a dozen N5X bots (but not N5 bots??)

I think it's something in python-adb. This line of code shows up in the logs of all the bots that drop offline:
https://github.com/luci/python-adb/blob/8626f278839300b6fc5e13559710ee6dbee9363c/adb/common.py#L156


 
Something clearly changed around Dec 8th that started taking them down: http://shortn/_tUYJCzuOs2
Welp. That lines up pretty well with https://chrome-internal.googlesource.com/infra/infra_internal/+/745a6584e0bc3d140cd8d1ce4a152eaabcf75c14

(Is there anything that that CL didn't break?!) It's since been reverted. I guess I'll just wait and see if things get better over time.
Status: Fixed (was: Assigned)
Things look more stable now.
