Some troubleshooting tips:
Make sure the USB cable is connected directly to your computer and not to a hub or docking station.
Try re-connecting (maybe in a different port) your RollerMouse or restart the computer.
Try connecting your RollerMouse to another computer.
Make sure you haven’t downloaded another mouse driver on your computer – it might interfere with your RollerMouse.
Try connecting someone else’s RollerMouse to your computer (and vice versa).
If there is only a problem when RollerMouse is connected to your computer, then the problem is most likely with your computer. If the problem with Roller Mouse is consistent and appears in the same way on any computer, then your RollerMouse unit is mostly likely the cause.
