deck target issues (was IMU Support for Steam Deck (on Gentoo))

[bell07]

The SteamDeck have IMU. If I use hid-steam kernel module, two event devices appears:

[ 1976.104829] hid-steam 0003:28DE:1205.0011: Steam Controller 'FVAA233050FE' connected
[ 1976.116986] input: Steam Deck as /devices/pci0000:00/0000:00:08.1/0000:04:00.4/usb3/3-3/3-3:1.2/0003:28DE:1205.0011/input/input66
[ 1976.117360] input: Steam Deck Motion Sensors as /devices/pci0000:00/0000:00:08.1/0000:04:00.4/usb3/3-3/3-3:1.2/0003:28DE:1205.0011/input/input67
[ 1976.118118] hid-steam 0003:28DE:1205.0015: hidraw0: USB HID v1.10 Device [Valve Software Steam Controller] on usb-0000:04:00.4-3/input2

This Motion sensors are usable trough evdev in dolphin-emu for example.

But if I run inputplumber and enable the handling inputplumber devices manage-all --enable , both devices disappear, and no of the new created InputPlumber uinput devices have motion sensors capabilities.

I am newbie with inputplumber, so maybe the issue is on my site. If this is not yet implemented, I am willing to test patches and provide additional information if needed.

In log I see the next lines:

Assume something is missed in default devices/50-steam_deck.yaml to be able to use SteamDeck's IMU

[bell07]

Ok, got the IMU working by using ds5-edge target device instead of xbox-elite.
Tried "deck" too, but got issues with an pygame app got errors with this target device.

[pastaq]

Can you post the pygame errors?

[bell07]

The software I use is https://github.com/bell07/lutris-ui, an very basic launcher.

If target_device contains the "deck", the error is
pygame.error: Unable to open /dev/input/event19 at joystick.Joystick(i).init()

    def init_all_js() -> None:
        joystick.init()
        for i in range(joystick.get_count()):
            joystick.Joystick(i).init()

If I catch the error, the pygame event.get() breaks with <SystemError>: <built-in function get> returned a result with an exception set

From InputPlumber I get the next debug lines:

Interesting, thanks. I've seen a similar error in InputPlumber when using the deck target while the kernel initializes the virtual device. Pygame should handle this more gracefully but I'll look into solving it. Does the same thing happen with deck-uhid target?

[pastaq]

Side note, our software OpenGamepadUI has a lutris plug-in. It works well to launch games in a deck-like UI, though you need to install games directly from lutris on the desktop currently.

[bell07]

Pygame should handle this more gracefully but I'll look into solving it.

Pygame just uses SDL. I think, the special case is the lutris-ui try to enable all connected joysticks at once.

Does the same thing happen with deck-uhid target?

deck-uhid is not in composite_device_v1.json. But I tried it shortly: get new device { id: "deck-uhid", name: "Valve Steam Deck Controller", device_class: Gamepad }, but evtest show me Keyboard keys on this device and no events.

Side note, our software OpenGamepadUI has a lutris plug-in

I maintain Gentoo ebuild for OpenGamepadUI, in my personal Gentoo repository and try each version. OpenGamepadUI does not match my needs currently

• If launched, I do not get the games list at the first but one "Lutris" Category
• Lutris downloaded game covers are not shown
• Feels not lightweight because of launch time
• I still not know how I can build godot projects from source in Gentoo Ebuilds

[pastaq]

Ah, yeah if you're using the evdev created by the kernel driver when steam doesn't have the hidraw open then it's not going to work unless you patch it to include the new PIDs, or patch InputPlumber to use the deck PID on the uhid target. We can't ship the deck PID on the deck-uhid target because that PID specifically only hooks into steam if the bInterfaceNumber matches, and that can only happen in VCHI.

If the controller works normally with hud-steam and you're not using OpenGamepadUI so you don't need intercepting, I'm curious what your use case for InputPlumber is?

[bell07]

My use-case is to replace sc-controller for key mappings because of some issues. InputPlumber is the only alternative that is able to manage the both touchpads too. In the meantime I found out the InputPlumber is really very powerful.

I added an simple bash script to lutris "pre-launch" and "post-launch", that swap the profile using inputplumber device 0 profile path "$profile". In my default profile the Guide is mapped to labwc shortcut for "minimize" to be able to exit any game. lutris-ui is able to terminate started game. The QuickAccess to shortcut to show OSK (wvkbd).

Maybe I implement intercepting handling into lutris-ui later, if I understand the needed basics.

Back to topic: I do not use steam client atm, all games are installed trough lutris. If I unload the hid-steam kernel module, then "deck" does the same as "deck-uhid", I just do not get any joystick device.

In my setup I am happy with the ds5 and ds5-edge (did not found difference except name) target, since widely supported and provide working IMU device. Maybe it could be set as standard in 50-steam_deck.yaml instead of xbox-elite because of IMU Support? The missed motion sensors was the reason for this Issue.

Additional idea is to add generic IMU only target device that could be used together with xbox targets.

[pastaq]

There are a couple possibilities for default target devices. The main reason we currently use the Xbox is because the iconography of tooltips doesn't match on the DS controllers. Currently only the FlyDigi Vader 4 has a working gyro, back paddles, and Xbox style layout, but we still need to add that as a target since it only recently got SDL support.

Ds5 edge has back paddle support where ds doesn't. For devices without back paddles or if you want the paddles supressed the ds target is better.
