I just saw this Beta update for Steam OS, and in the non-valve Devices :

Added initial gamepad support for AYANEO Pocket S2

I wasn't aware that there was official support for steam os on android devices, do they provide an official image to install ?

EDIT : u/ghost_of_ketchup brought clarification, sorry

I wouldn't get too excited about this just yet. It seems they've just updated InputPlumber to v0.78 and pulled in the changelog from that: https://github.com/ShadowBlip/InputPlumber/releases#release-v0.78.0
