Hi,
I'm surprised that this doesn't provide a virtual serial port. Double-check
that. If it does, then you simply use MSComm (or whatever) just as you
always have.
If your GPS device doesn't provide a VSP, I suspect that you are SOL. You
can refer to Jan Axelson's book, USB Complete, 2nd Edition for information
on the various ways that you can interact with USB devices using VB (see
Books on my homepage). However, this will not be a HID device, so using
Windows USB APIs, which deal with HID devices, like keyboards or mice, is
out of the question. You'd have to use some API provided by the device
manufacturer.
