The back paddles aren’t mapped to anything by default and there’s nothing Steam can do to help there. There are also some vibration levels you can’t set elsewhere and having a hardware switch for different profiles is nice.

The back paddles also can only be mapped to other buttons that are on the controller so I need different profiles for different games. I usually map them to l3 and r3 but sometimes its nice to have them as b and y instead without having to mess with steam input.

I’ve been very happy with an 8bitdo ultimate using the 2.4 ghz dongle. Only complaint is I can’t modify any mappings on Linux and have to bust out an old windows laptop for it. Otherwise, it’s worked perfectly every time across a few Linux systems including a steam deck.

It was a little silly to have to change a setting away from the default given that nearly everything works on proton.
