When I install the USB driver and connect the sensor, the mouse cursor moves randomly and clicks on various places.

The USB type sensor is sometimes mistakenly recognized as a serial mouse. It is known to occur when the sensor continues to output data at the time of connection. The USB connection type GPS receiver seems to have this ossie as well, and the same countermeasure should solve it. http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/windows-7-recognized-usb-gps-as-a-serial-mouse-in/ 0c3f0d94-6181-4a43-9e90-bcea8a21415d
