Thanks for verifying. We should check if the controller is authenticating next. Please disconnect and reconnect XIM to the console while watching XIM's startup light sequence. Do you see 4 green lights during this sequence? This indicates controller authentication and is needed for your mouse and keyboard to function. For reference the startup light sequence should look similar to this:
red, green, blue
red
cyan, green,
red
green, green, green, green
red
If you do not see 4 green lights at startup and you have spare cables please test other cables with the controller.
