Steam does not always see my controller in-game

[prototact]

@dosu my controller Razer USA, Ltd Razer Wolverine V2, is not seen by games running natively on Linux (launched via the Steam platform). the device is normally viewable from Steam itself. I tried turning on and off the steam input but it does not work. How can I configure Steam or Flatpak, in order for my controller to be usable in-game?

Steam can see your controller but games can't because Flatpak apps like Steam are sandboxed and need explicit permission to access hardware devices. To fix this, open Flatseal (install it from Flathub if you don't have it), select Steam, and make sure "All devices" and "Udev" are enabled. This gives Steam and its games access to your controller. You can also use the CLI:

flatpak override --user --device=all --filesystem=host --talk-name=org.freedesktop.UDisks2 com.valvesoftware.Steam

After changing permissions, always plug in your controller before launching Steam—hot plugging isn't reliably detected in Flatpak Steam.

If your controller still isn't detected in games, check that it's visible to the system with lsusb or evtest. Some controllers need custom udev rules for full support; Bluefin ships rules for some devices, but not for the Razer Wolverine V2. If you need to add a rule, you can model it after the HORIPAD example.

tldr: Use Flatseal to grant Steam device and udev access, and always plug in your controller before starting Steam.

To reply, just mention @dosu.

Do you know if this device needs udev rules to function in Linux?

Works in bazzite and aurora so should be working? https://linux-hardware.ru/?id=usb:1532-0a2e&page=1#status
