Re: 2012 Field Comm. Issue Logs

We experienced what were usually short blips where we could not control the robot, and it simply sat there. The FTAs would comment that they usually saw the comm blip, but we never saw comm drop on our driver station. One of the FTAs (Jerry) inspected the logs from our driver station, During the time that we lost control, the battery reported constant voltage, confirming that nothing was running on our robot. Nothing in the log looked "wrong." When we regained control, the ping time would spike.

We suspected that it was a bad USB cable connecting our OI, and that we really did stop giving the robot commands. However, we replaced the USB cable, and the issue persisted.
