According to my research, the USB-C port on the ROG Phone 6 is unfortunately not centred, which probably makes it impossible to mount it on the Backbone One. Unfortunately, Asus is also not listed as a compatible brand on the manufacturer's website.
Unfortunately, only if it is a very thin case (Latercase, Peel). I have the FineWovem from Apple and a Clearcase and both are too thick. A disadvantage of the Backbone Controller.
Depending on the firmware version, the USB-C variant must first be connected to an Android and updated.
