1310 experienced a similar USB input device problem twice during the build season. We were never able to deterministically repeat it, however we saw all the same symptoms.

We use one Logitech Dual Action Gamepad and one Logitech Attack 3 Joystick (w/ modified internals) to control our robot.

On both occurrences of the problem, the devices appeared in the list of USB input devices in the DS. I do not recall if pressing buttons on them caused the LEDs to turn blue. However we printf'ed the getRawAxes on both joysticks and received nothing.

Simple replugging of the joysticks did not solve the problem.

Ultimately, it required us to quit the DS app, unplug the entire supplied USB hub, plug in one of our controllers directly to the Classmate, verify the OS re-install the device driver, unplug the device, restart the DS app, plug the hub back in, and reorder our input devices - the enumeration doesn't always put them back in the order that we need them in.

Right now, I'm a little weary of the Targus USB hub that was supplied. I'd like to know if you're using it as well? Beyond that, I'm a bit stumped as to the cause of the problem.
