Similar issue -- Logitech sent this to me.



- Click on Start and Choose Control Panel

- Choose Add and Remove Program

- Uninstall any programs stated as Logitech Setpoint / MouseWare.

- Restart the computer and proceed to test the device in embedded mode.
(Without the software)

- Test on another USB port

- You may also test this product on another computer if available



You can then manually install Setpoint 4.4.0 downloading it from Logitech.
