Well, AFAIK you can't convert USB data to serial without some sort of Chip/software to control it, so I'd say that you have a serial GPS mouse (otherwise why pins 5-9 etc?) that is converted to USB and by wiring to the pins you have you are by-passing the USB conversion!

But well done for finding that!
By the way, what area are you in? We're skiing next week at Sierra Nevada, woo hoo!
