Your system information

• Steam client version (build number or date): Dec 15 2022, at 21:27:25
• Distribution (e.g. Ubuntu): Arch

Please describe your issue in as much detail as possible:

Steam does not see host gamepads when using Remote Play Together. Guests gamepads are fine though (tried Windows). Gamepads are indeed connected and work well in game, both Steam and non Steam. But can't be seen by Remote Play Together.

Steps for reproducing this issue:

1. Start a Remote Play Together session
2. Look at "Game settings" inputs in Remote Play Together Window.

We poked around a bit more:

If a friend of mine joins, and its gamepad is recognized it automatically appears in slot 2. If I drag and drop its gamepad to slot 1 then my own gamepad magically appears in slot 2, my friend's gamepad taking slot 1. I can then reorganize them at will, and my gamepad works ingame.

This is fixed as of March 20 2023's build. Thank you !

Reopening as it happened again. Tried with Lara Croft and the temple of Osiris.

I found a temporary workaround : Enable steam input. Right click on the game, properties, Controller, Enable Steam Input in the combobox. Launch the game and start a remote play session. All your controllers (host) will appear.

I'm having a similar issue where, even after installing game-devices-udev and installing steam-input udev rules, any user that joins me in remote play is unable to use controllers. my own controller is fine; other people's controllers wouldn't work.
