GS407 in tablet pc

Hello,

I’d like to install a GPS unit inside my tablet pc, just like this guy did - http://forum.eeeuser.com/viewtopic.php?id=29099 . He used GS405 with RS232 to USB converter and voltage regulator. I have room inside and access to usb port, case is made of aluminum alloy so I decided to go with external helical antenna.

My question is - since GS405 is not available anymore - will GS407 do the same trick? Or is there a way to connect a GS407 directly to the USB port?

Thanks.
