That's really strange. All icons are displaying in Manager, the firmware is correct, the flash tool works, the controller works in wired mode with the console. This should be working. Please try connecting your XIM4 to the console with nothing attached. Once APEX has finished it's startup then connect the controller to port 3 and look for the 4 green lights. If they don't appear then try using the controller in other ports on XIM4. The results will tell us if there is a power issue, a peripheral conflict, or a port issue.
