I've had this mouse for a few years. Haven't used it because there's something wrong with the usb and it won't go into the port. So when you pick it up, face it toward you it has this extra slot thing which is there. I'm not sure if that's normal, I also have no idea how to explain it. Heres pics. Razer mouse: Another mouse: Clear difference. The other mouse is able to slide in the usb port while the razer one can't. Can I fix this?
