Mike, go into Control Panel / Mouse, and see if the next dialogue has a tab for your touchpad. If so, choose that and see if there is a checkbox that says something like, "Disable internal pointing device when external USB pointing device is attached". If that is not checked, check it. Once the change is applied, you will probably see the touchpad active light go out and hopefully your mouse will be recognized.
