Also, to clarify: by "shortcut the port", do you mean to jumper the ground line to the signal line (the two outer pins) to each other, leaving the supply line (center pin) disconnected?

If so, we were having a problem with touch sensors on our lift face that may have had this issue. We had assumed that this was a problem in our code, but we back-burnered the problem because the touch sensors were getting beaten up too badly anyway as our driver practice picked up speed and moved on to things we are more likely to get working by Wednesday evening. I believe that programming will have use of the practice 'bot on Tuesday; I'll see if we can work in a simple test to see if it's perhaps a hardware issue.
