steam-devices VS evdevhook

if you mean this ( https://github.com/ValveSoftware/steam-devices/blob/master/60-steam-input.rules ) in /etc/udev/rules.d , yes i did

Create an udev rule for the device, you can copy the rule for your device from here.

I am attempting to play Spelunky with a controller but I am not having any luck. Spelunky has a platinum rating on protondb and runs as expected. I am in a flatpak and I did install the udev rules from valve if any of that makes a difference. My controller works fine in native games.

I solved the problem by copying the 60-steam-input.rules file to the folder: /etc/udev/rules.d

this is their Github: https://github.com/ValveSoftware/steam-devices

steam maintains udev rules for controllers that might help: https://github.com/ValveSoftware/steam-devices/blob/master/60-steam-input.rules

Here is my open PR for the hori alpha for reference: https://github.com/ValveSoftware/steam-devices/pull/42/files

To use a controller with the Steam flatpak, you need to layer the steam-devices package from RPM Fusion, or download the udev rules from upstream and install them to /etc/udev/rules.d/ (which is what I did).

> The effort you need to go through to actually use these depends on how your distribution handles the file permissions of /dev/uinput. Some of them have it as root:input, in which case you just need to usermod -a -G input and then relog to get it working. Others have it as root:root so you either need to go do some reconfigurations to change its permissions or live with running the software using it as root.

There's a trick to that. The TL;DR is "install the steam-devices package or similar" (https://github.com/ValveSoftware/steam-devices/), which adds the following udev rule (and others, but this is the relevant one):

  # Steam Controller udev write access

By default, evdevhook currently has an axis inverted on the DualSense, which you can fix with a simple config file change.

As suggested at https://github.com/FrogTheFrog/steam-gyro-for-cemuhook/issues/47 you could try out using https://github.com/v1993/evdevhook. My Steam Deck arrives Q2 so I can't tell you if this works at all - would be cool if you/someone could tell us :).

Motion controls work. For emulators that need a cemuhook-style DSU protocol server, check out the evdevhook project.

I'm on POP OS and my dualsense controller works fine. I followed this guide though (https://christitus.com/ultimate-linux-gaming-guide/) to install the xanmod kernel which might have the dualsense drivers in it. When I finished setting up everything I just pressed the Share + Playstation button the dualsense controller then searched for devices on the bluetooth device manager. Besides that evdevhook (https://github.com/v1993/evdevhook) is good for motion controls on CEMU and Dolphin.

Joaorb64's joycond-cemuhook and v1993's evdevhook are probably your best options. I can't speak on either since I've used neither.
