So the other day I visited a friend of mine to play a little Street Fighter and I brought my Fightstick. He had just purchased the PS Move bundle along with the game "Sports Champions". The game requires a calibration run before playing. But no matter what we did (change lighting conditions, move further away from the Eye, etc.) the thing just wouldn't calibrate. The solution was to unplug the TE fightstick from the second USB port! The problem was reproducable and we also switched PS Eye and Fightstick getting the same effect. Rather odd bug which may have to do with firmware 3.50's USB changes.
