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.
