OK I have the Logitech g13 and 3d extreme. if i use just the 3d extreme with the keyboard i don't have any problems. as soon as i plug in the g13 game board i get a dead stick. I'm not quite sure whats causing this but the only way to get the stick to work again is to unplug the g13 and reboot the computer. any help with this problem would be much appreciated.
