I've got a Logitech 305 wireless mouse. Works great with my Macbook. I've had the stubby little USB dongle plugged into the side of my laptop for a long time and after a little accident, some upward force was applied to the dongle and the black plastic part snapped off. Picture related: That's what it looks like now. I plug it in and it still works, but I'm wondering if there's any way it can be repaired or replaced? Not the entire mouse and all, just the dongle? Thanks. EDIT: After some more testing, the mouse only works intermittently now. I need a replacement for the dongle.
