DualSense Wireless Controller "disappering" after some time

[TuxThePenguin76]

Problem:
my PS5 Dualsense controller randomly stops working in proton games after a few minutes. In both wired (USB) mode and Bluetooth mode

Games tested:

Bayonetta
Clair Obscure: Expedition 33

Proton versions Tested:
Proton 9
Proton Experimental
Proton Hotfix

Symptoms:

It works initially and then suddenly stops and I can only use the keyboard and mouse. If I quit the game and restart it works again for a while.

If i go to the main menu -> steam -> settings -> controller then the controller shows up and the test input reports everything is working correctly.

I have also tested with native Linux games Left for Dead 2 and Portal 2 and both ran for over an hour without a disconnection.

@TuxThePenguin76 If you are able to grab a log of this failure with some extra logging channels, that could be really useful. PROTON_LOG=+hid,+hidp,+hid_report,+plugplay,+rawinput,+dinput,+xinput,+joystick,+setupapi,+input %command%

Also - please also copy your system information from Steam (Steam -> Help -> System Information and Steam -> Help -> Steam Runtime Diagnostics) and put each in a gist, then include a link to the gists in this issue report.

@TuxThePenguin76 Also - in the games where you are seeing this - do you have steam input enabled? Another thing to try would be enabling/disabling steam input.

I have tried with and without steam input. I will get the logs later

Just to give another data point and also rule out the controller itself, am getting this with an 8BitDo 2C Wireless controller (connected through 2.4GHz dongle, have not tried wired or Bluetooth).
Game: Marvel Midnight Suns
Steam ver: Stable channel v1745876290
Steam Play: default settings
Happens with and without Steam Input enabled.
Usually run whole steam instance through gamescope but it happens when run natively as well.

I think it might be every 15 minutes, which is what the idle controller power off setting is currently set to in Steam. Will try changing that and see if helps.

Can grab logs later if needed.

EDIT: after disabling the controller idle power off setting in Steam, have not had this re-occur during latest gaming session

[TuxThePenguin76]

Idle power changes haven't made a difference forr me. I'm trying to look through the log i've created but I'm just learning what all the log messages mean

[ammgws]

I just had it happen again after a few hours, even with the idle power settings turned off. But at least it is better than before when it was happening within minutes.

I've just had a successful 1h session forcing version 9.0-4
I think all previous runs may have been on hotfix, experimental or beta,
I will continue to test
