Claiming a USB HID device

Hi there, this is my first time asking a question on The Code Project, so please bare with me.

I've written an application that reads input from a USB HID device. It's a programmable keyboard with 35 keys, a Controlpad 682 for those that are interested. This device sends normal keycodes. Nothing special there. I'm able to receive input using the Raw Input project (http://www.codeproject.com/KB/system/rawinput.aspx[^]. So far so good.

The problem, however, is that when another application has focus, it too receives the keycodes sent by the Controlpad. I'm trying to find a way to prevent this from happening, however my google skills are letting me down...

So I'm hoping that someone here might know how to do this. I can't be the first to ever have tried this. Please, help me!
