But this weekend at Arizona, they started acting up Friday afternoon, where they would appear to be connected, then just after the match started one or both would "go away". Sometimes they came back with a USB Rescan, other times they needed to both be unplugged and reconnected.

The problem got worse late Saturday, in our final few matches we had to Rescan several times during the match to keep driving.

There was one code change before the issue started Friday, we added a vi module to make one of the buttons act as a toggle.

Each gamepad is connected to a "real" USB port on the DS laptop, there is no external hub. The laptop is on it's 3rd year, and has been working well.

We have seen a similar issue. Every time it has happened to us it has been because of a fault in the cable for the Logitech gamepad controllers. We do our best to have the students treat them with a bit of respect but they just get beat up.
