Did you set the device output in Cronus PRO to AUTOMATIC? Again, very important - the controller will disconnect every 10 minutes on a PS4 otherwise.
Did you desync/unpair your wireless DS4 from the PS4 before starting? Again, very important - the controller will disconnect every 10 minutes on a PS4 otherwise.
Is the USB Hub logo in the Cronus PRO status bar gray and the firmware version is 1.21 or above? If yes, the USB Hub feature will not be supported.
The PS4 controller has to be connected to Port 4 of the USB Hub by a micro USB cable. It's possible your cable could be faulty or not full data compatible.
The Xbox One controller has to be connected to Port 1 of the USB Hub by a micro USB cable. It's possible your cable could be faulty or not full data compatible.
The Xbox 360 controller has to be a wired controller - not a wireless controller with a play and charge kit.
If your Xbox One controller is taking longer than usual to authenticate (CronusMAX PLUS LED spinning animation) double tap or hold down the Xbox Button - it will authenticate in a couple of seconds (CronusMAX PLUS LED changes to 0)
Try connecting the crossover controller to Port 3 of the USB Hub.
Try connecting the CronusMAX PLUS into the console first - wait a few seconds - then connect the USB Hub. You must do this before AU appears on the CronusMAX PLUS LED or you'll have to reconnect the CronusMAX PLUS to the console and start again.
Remember that console power cycles must be done by the power button on the console, not by the controller.
Experiencing lag? Some USB Hubs cause lag - in particular the ELECOM brand. Try another brand.
