I am using a Asus ProArt z790 MB and configured OpenRGB as indicated above. I no longer get the warning message and OpenRGB is able to detect the AURA lighting RGB headers, but I'm still unable to get it to detect my Corsair Vengeance RGB RAM. Do I need to pass through additional i2c devices like in OP's? or just keep the default /sys/bus/i2c/devices and /dev/i2c-0 ? As part of testing I passed through all 12 of my i2c-X devices without any change.
