Load Cronus PRO and go to Tools > Options > Device
Set the Output Protocol to XB360.
These are also the recommended default Speed Up Settings for Wired Controllers. Rumble Over Bluetooth is disabled as it's not being used.
You can now close the Options window and disconnect your CronusMAX PLUS from the PC.
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.
