Does it not respond at all in-game? There is no default profile for the DFGT so you'll have to create one yourself, or download one that someone else has made. The DFGT should still appear in the top left box on the controllers screen though, alongside 'keyboard' and any other controllers you have connected. If its not there, unplug all other controllers. Some games just don't like multiple controllers, regardless of what their ID number is set to.
