 They WILL work   IF....

1)   Your computer has USB ports.

2)   Your operating system properly supports USB; ie Win98SE or later

3)   You are running APRS on a computer.

The USB-interfaced GPS is TOTALLY USELESS when you want to connect a GPS 
to a hardware device such as a TInyTrak, KCP3 TNC used as a dumb 
tracker,or a TH-D7 or D700 running in standalone (no computer used) 
mode.    The virtual serial port is entirely a creature of WINDOWS-BASED 
drivers intercepting the USB data stream.  If you use a GPS with a 
non-Windows device, the GPS must have an actual serial interface.
