Can I get a bit of help with the same issue?
G29 connected to Xbox One S, Crosshair using "Expert profile (Beta)".
The crosshair lights up and the G29 (in PS4 mode) has a green LED beside the PS3/PS4 mode switch, the wheel turns on and calibrates.
It seems that the Xbox isn't receiving any input from the G29, I tried pushing every button whilst in a game and there was no response from any of them.
I saw in the setup PDF, that the controller (standard, hand held, not steering wheel), should be connected to the left port of the Crosshair. My Xbox controllers are wireless. Do I need to buy a USB lead controller?
