Disabling Ballpoint mouse when conneting GPS

I need to find a way of disabling the auto installation of mouse pointer
drivers in Windows XP, specifically the "Microsoft Serial Ballpoint" mouse
but other Microsoft mouse pointer give problems too. I am having problems of
the mouse pointer jumping all over the screen whenever a GPS device is
connected.

I have seen this problem posted before but all suggested solution make use
of either disabling the device in device manager or setting SkipEnumeration
key in the registery. Both of these solution only work AFTER the problem has
occured: i.e. after the system has incorrectly detected that the new hardware
is a "Microsoft Serial Ballpoint" mouse or similar and installed the driver
thus making the mouse pointer jump all over the screen. Remedeal action
(disabling in device manager or registry changes) is then required.

Unfortunatly this is not suitable for my situation. The system I have relies
on the end user (customer) connecting a USB GPS devices themselves. The user
can install the GPS device in one of many USB ports connected to the system
and could use a USB hub. The device will also change USB port as it is
connected and disconnected regularly, not always returning to the same USB
port. A different USB port will be seen by XP as a different (and New) device
and therefore new drivers will be installed even if a previous Ballpoint
Mouse driver has been disabled in Device Manager.

The system in question is a tablet system and therefore touchscreen only so
options like disabling in Device Manager are very difficult.

I am therefore looking for a way of disabling the automatic detection of
mouse pointers. The ports should simply be recognised as RS232 Serial Com
ports, nothing more. Automatic detection of mouse pointers is not required on
this system.

Is there anything that can be done to the .inf file
(C:\WINDOWS\inf\msmouse.inf) which lists the Ballpoint mouse device to stop
it from automatically installing?
Or is it possible to remove completely the driver (sounds a bit excessive!!).

Thanks
