The Blog Post for Crazy Mouse Syndrome is good in most cases, but not with any of our products that take their power from the USB interface. You cannot “turn off” a USB powered device (to make the mouse stop being crazy) without unplugging the USB connector, which immediately removes the device from the Device Manager, making it impossible to disable.

To fix the problem in this case, involves a different, slightly more “geeky” approach – editing the Windows Registry.

With the USB GPS unplugged, click on the “Windows” key and type regedit in to the search box. The Windows Registry Editor (System tool) should be the top result and if you run this and then allow it to make changes to your PC, a Windows Explorer type screen will appear that lists all of the Registry settings on your PC.

Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicessermouse  and then change the value of the Start key from 3 to 4.

Once you have made this change, close Registry Editor and reboot the PC.

Your GPS 160 USB should never be detected as a serial mouse again – unless a Windows update changes the registry values.
