It's not necessarily a quick fix.  There's no guarantee the USB GPS 
receiver is using a protocol that the host IC can use.  Take a look at 
the USB to serial drivers in Linux - there are a lot of them.  And 
Garmin USB GPS receivers use something completely different from all of 

I've looked at making an adapter, but with serial GPS receivers still 
being pretty cheap, there's no real justification for it.
