Control Usb
Where can I find information on writing code to control a USB device?

I have a device of my own creation that requires discrete signals. I have a STAMP (and a couple of other devices) for converting serial to discrete. What I am looking for is developers information on the software side.
TIA.

you kinda need to know how one device tells when the computer is talking to it, and not the next device down the line

If you don’t have a USB controller on your device, then you are goin to have to deal with usb protocol
