How to Interface to USB

I posted this in Activex.Writing and was told this might be a better place
for it, so here it goes...

-----

Using Delphi5. I'm writing an OCX to track a vehicle position from live GPS
data. I was using a serial GPS and had no problems, I was reading the data,
processing it, etc.. However, a client needs to use this with a GPS
connected through the USB port, and I don't know how to read the data from
it. Is there any specific information, on how to get data from the USB
port? Are there any controls that I may need to get/license to let me
communicate with the USB? What can I do?

I am really desperate, so any information, help, suggestions would be great!
