Phantom PS/2 Mouse

I currently have a Logitech wireless mouse connected. In Device manager under
hidden devices I have "This device is not present, is not working properly,
or does not have all its drivers installed. (Code 24)" in addition to entries
for my logitec mouse. There is nothing connected to the PS/s port. My
wireless mouse is connected to a USB port. When I uninstall this "Phantom"
device it reappears on my next reboot. How can I get rid of this, or does it
matter. The computer runs Vista normally otherwise.
Thanks
Bob
