I've had my Xbox One from "day one" and it's worked fine, until an hour ago when the controller ceased to function. I replaced the batteries, ejected the game cd that had been in the console, turned the console off, turned it back on, logged out, logged back in, and even tried usb connecting it to the console. Basically, everything that has been recommended for pairing issues.
If I turn the console off, it turns the controller off, so I know that it's still paired, but none of the button presses register with the console at all, whether usb-wired or wireless. Has anyone else experienced this?
