Unfortunately if you've got to ask how to set about it then the problem is too difficult for you.
You've got to poll the USB devices, then you've got to interact with the Windows kernel to put a layer between other programs and that USB. I've got 20 year's experience and I can't tell you off-hand exactly how to do it, basically it means reading lots of technical Windows docs. It might not even be possible (though that's unlikely).
