Has anyone gotten this to work? I have both the SN30 Pro and the Pro 2, both display the latest firmware update as 2.06 which just lists Switch 2 compatibility. Steam doesnt seem to recognize the back buttons on the Pro 2 either.

I play a lot of beamng drive an having them for extra binds is nice, like the horn and changing gears

AFAIK the current anticheat systems on Linux only run in userspace not at kernel level. This does mean Linux is theoretically easier to bypass compared to windows, some games just dont seem to want to take that risk. For as you said 3% of the market.

I personally disagree with that stance though, because all it takes is a hardware device and all software anticheats are useless no matter the os (think a raspberry pi, and capture card). So anticheat is really a losing battle anyways.
