Hey, I've recently bought a SteelSeries Arctis 1 wireless headset: https://steelseries.com/gaming-headsets/arctis-1-wireless-xbox and wanted to write a kernel driver to export a few features of the device, and needed some help getting started. The receiver shows up as a audio class USB device, with extra features on a separate USB interface.[1] The extra features that can be accessed are: - Presence detection. I wanted to use that so PulseAudio or Pipewire could make routing decisions based on whether the headset is available, or probably better, implementing a "jack detection" emulation for the main audio interface? - A slider to change the sidetone volume - Export the battery level The latter is the only one I know how to do, so I'd be happy with any pointers or examples about the first two items. Cheers [1]: User-space code that accesses those features: https://github.com/Sapd/HeadsetControl/blob/master/src/devices/steelseries_arctis_1_xbox.c
