Using a USB Hub

Using a USB Hub
Set Output Protocol
Follow the instructions here to correctly connect your CronusMAX PLUS to a PC via the PC PROG port using the supplied Mini-USB Cable.
Load Cronus PRO and go to Tools > Options > Device
Set the Output Protocol to AUTOMATIC. (IMPORTANT - If not set to AUTOMATIC then the USB Hub will not work correctly).
These are also the recommended default Speed Up Settings for Wireless Xbox 360 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 your PC.
Prepare the USB HUB
Using a Compatible USB Hub (USB 2.0 or lower is recommended) connect the controllers as follows:
If you do not know the USB hub port numbers, click here for a guide on how to discover the port assignments.
Some USB Hubs prefer the Cross Over controller to be on Port 3, just make sure that when you power cycle the console that the CronusMAX PLUS completely shuts down (No LED) and doesn't sit in standby mode (Spinning Animation LED), otherwise on reboot the authorization won't work correctly. Note: To correctly shut down the console, usb hub and CronusMAX PLUS, power cycles must be done from the console, not the controller.

Connect the USB HUB to the CronusMAX PLUS
Now that your controllers are connected to the appropriate ports on the USB Hub, connect your USB Hub into the Input Port of the CronusMAX PLUS.
Connect the CronusMAX PLUS to your Xbox 360
Connect the CronusMAX PLUS into one of your Xbox 360 USB ports via it's Output Port.
The CronusMAX PLUS LED Display will now show the Authentication 'AU' Animation.
If you get this error code you have not updated to the latest firmware (at least v1.21). You must do that before you proceed.
Sync your Xbox 360 Wireless Controller with the Wireless Receiver
This step needs to be performed only the first time as the information is then permanently stored, you can skip straight to Step #7 in future.
• On the front of the controller, firmly press the large Guide button in the center. The controller will turn on, the Guide button will light up and green lights will flash around it.
• Press the connect button on the Wireless Gaming Receiver. The light will flash green. On the controller press the connect button, it is on the side, roughly in the middle, between the two shoulder triggers.    
• The lights on the controller will flash and revolve to show it is searching for the Wireless Receiver. Wait until the lights stop flashing and remain on in one of the quarter sections around the Guide button.
Press the Guide button on your Xbox 360 Wireless Controller
If you have previously performed the above step, Simply press the Guide button on your Xbox 360 controller.
The LED on the controller should start blinking, meaning the controller is tying to connect with the CronusMAX PLUS/Wireless Receiver.
Ready To Use
After a couple of seconds the display on the CronusMAX LED will go from the Authentication 'AU' 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!
The Authentication controller will be disabled. It will not vibrate and none of it's controls will interefere with your Crossover experience. It can safely be left sitting idle on a surface as if it was turned off.

If the LED on the CronusMAX PLUS does not change from AU to a number then the authorization controller is not authenticating. 99% of the time, this means either you didn't set the Output Protocol to AUTOMATIC in Step 1 of the instructions, or 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.
