This is still very confusing to me. So let me see if I understood you.
You have a USB camera, say like a Logitech web cam. You want to plug
this into the frame grabber that you are designing. Your frame grabber
has a USB input port on it. Then you want to pass this USB signal on
through your frame grabber into the USB port of your computer. Is that
right? If that is right, it seems to me you don't need any circuitry
at all - just simply an adapter to connect one USB cable to another
(just wired straight through). But in that case, why not just plug the
camera into the computer directly? What is your "frame grabber" doing
and why is it necessary?
If you have an analog camera, there are simple $60 frame grabbers/video
digitizers that will take a composite or component video signal and
digitize it and send it into the USB port of your computer.
Obviously I don't have a full understanding of what you want to do --
you must want to do more than to simply pass the signal onto the
computer -- so please explain in much more detail.
