I've used my Logitech MX-400 laser mouse for a few months now, and I've been able to take advantage of all its special features (tilt wheel, side buttons). I recently installed Steer Mouse just to try it out and then tried to get rid of it. However, the Logitech Control Center prefpane no longer detects my mouse. So I'm stuck with using my mouse without its extra buttons. I've tried reinstalling the Logitech Control Center and it still doesn't detect my mouse. Tried both USB ports as well. I just installed Leopard and the problem remains. What should I do?
