Steam Controller support

[xenolex]

Is it possible to add steam controller support something like simple Xbox controller emulation ?
The native gfn app is not see steam controller at all.
Maybe something like made in boosteroid when all controllers are xinput controllers?

This is much more complicated than it sounds. On the original opennow i have found the fix which works on how it is chrome based like for Electron as you can see here OpenCloudGaming/OpenNOW#582, with that said, the way Chrome receive the input allows GFN to actually translate to the input. The reason GFN native doesn't work and also the same reason here opennow-mac is because it uses the GCController and the Steam Controller is currently not visible into it.

At the USB level it doesn't even claim to be a gamepad: it enumerates as a keyboard + mouse ("lizard mode", for driverless desktop use) plus a proprietary vendor-page HID interface (usage page 0xFF00) that carries the real button/stick/trigger data in Valve's custom report format with that said, macOS classified it as a keyboard and mouse; GCController.controllers() returned an empty list; the app's monitor counted zero gamepads, never started forwarding, and the stream session was even negotiated with no controllers attached.

With that said i have an workaround here on my fork at this branch https://github.com/anderson-oki/opennow-mac/tree/feature/steam-controller-support, which i have been using for a couple days that works. However you need to have Steam closed on your Mac otherwise Steam will "steal" the connection. I wrote a custom IOKit HID driver.

Anyone feel free to test or read the code, i can also open a PR if anyone is interested, there are many caveats, if you want to test you can build by yourself and enable in the Experimental Settings.

Thank you, @anderson-oki , I built an app from your branch, turned off steam, but the app cannot recognize the controller as a controller, only as keyboard and mouse.

Did you enabled Input Monitoring in the System Preferences and gave permission? Also might be related on how you Signed. Also did you enabled the Experimental setting and restarted?

Try opening a game and check if Steam recognize as a controller.

Also to be honest ive mostly using this using the Puck, i dunno if it works with bluetooth

Enable steam controller support
Made restart

Input is on in settings

No luck

Only mouse and keyboard mode in app with or without interface controller mode on

What do you mean "how you Signed"?

@xenolex Open an Issue on my Fork so we can discuss there, so we dont polute this issue.
