* FMS showed good communication with both the DS and robot as well
* The robot drove in autonomous (strong hint!)
* The robot did not respond to driver controls in Teleop

That sounds like our symptoms except we weren't running an automode. Is the DS information logged somewhere in our system so we can examine it when we get back to the pits?

It usually turned out to be a USB hub that was either defective or attempting to draw too much power from the Classmate.

I'm doubtful this would be the problem since we used the same USB hub the whole regional and we only had an issue that one time, but I'll keep that in mind.

Often the IO board was plugged into the Hub (should be plugged directly into the Classmate because it's a real power hog).

We weren't using the IO board during the competition, so no issues there.
But I've gotten a bit off topic here. I will certainly concede that it's possible our robot had some sort of random error for one match. But there seemed to be a general pattern of that one driver station having issues across several different teams, and those teams never had issues in any of the other driver stations. I'm trying to figure out if there's anything field related that we should be watching for once we've eliminated the usual suspects?
