Windows 7 recognized USB GPS as a serial Mouse in Windows 7

*original title - Windows 7 + USB GPS becomes Serial Mouse = Bad News*

I know this has been asked quite a few times on here, and a solution has yet to appear, but since it has been awhile since the last time it was posted I thought I would see if any progress has been made.

Problem:  Plugging in a USB GPS, or a serial GPS connected via a Serial->USB adapter causes Windows 7 to improperly recognize the device as a serial mouse, and since the data stream is rapid, the mounse pointer begins to jump all over the screen.  In XP, disconnecting the GPS temporarily left behind the serial mouse in Device Manager, and disabling it there would then allow the system to be used again.

Unfortunately, in Win 7 when the GPS is unplugged the system immediately removes the device from Device Manager.

Additionally, the tools Microsoft had released to combat this problem on the front end have not been released for Windows 7. 

 So we have the choice, continue to hold the laptop rollout, or revert to rolling them out with XP.  Neither option is ideal.

 Anyone have any ideas?
