Home button on bluetooth controller shows as keyboard and can't be mapped

[penx]

I have a Retro-Bit Mega Drive Bluetooth Controller.

The controller can be started in a few modes (e.g. holding down home+A), most of the modes allow me to map all of the buttons apart from the 'home' button

When I hold a button down on the "Configure Input" screen, it correctly says "Retro Bit Bluetooth Controller" at the bottom, however if I hold the home button down, it shows "Keyboard".

It seems that the button is detected, but when I'm in the "Configuring" screen, it won't let me use the home button.

Any ideas?

If I start the controller with home+X, I can map the home button but not the Z and C buttons.

@penx Did you ever solve this? Got the same issue myself now. Thought I'd found a post of someone finding a solution yesterday, but can't seem to find it now.
