I hate to do this to you...
but you're going to have to look at the new controllers. They're not showing up on the XIM4.
The new controller is Bluetooth enabled, and the first thing I had to do when connecting it to the xbox, is to update the controller... so I'm willing to bet that you're going to have to release a new config of XIM.
I know how to correctly hookup my setup with the PS4, and that comes up right away. However, the new Xbox controller only buzzes for a second and then does nothing. Pairing has no effect.
