WARNING
If the LED on the CronusMAX PLUS does not change from AU to a number then the authorization controller is not authenticating. 9/10 we find that this means the Xbox 360 Wired Controller is not compatible for authentication purposes, you should try another one. Also make sure the controller is powered on of course - that's a rookie mistake.
Connect your Crossover Controller to the CronusMAX PLUS
Connect your Wired Controller of choice into the Input Port of the CronusMAX PLUS. If it's an Xbox One or DualShock 4 Wireless Controller use a full data Micro-USB Cable.
After a couple of seconds the display on the CronusMAX LED will go from the spinning Standby Animation to 0 (or a number if slot recall is enabled and a script was previously loaded) - indicating that the controllers are authorized and you're ready to play. At this point you can use your controller through the CronusMAX PLUS and also load any scripts or GamePacks. It's that simple!
WARNING
If you are using an Xbox One or DualShock 4 Controller with a Micro USB cable and the LED on the CronusMAX PLUS changes back to AU then the Micro USB Cable is probably faulty or not compatible. Try another and make sure it is full data and not just a charging cable.
