Could someone give advice on if/how to configure a USB media control device to adjust volume and other settings?
OpenBSD 7.9, arm64, on Raspberry Pi 5 with USB audio device (for audio output, not for any controls) and USB media control device "OZU8" dmesg has: uaudio0 at uhub1 port 2 configuration 1 interface 1 "JDS Labs JDS Labs Atom DAC+" rev 2.00/2.12 addr 2 uaudio0: class v2, high-speed, async, channels: 2 play, 0 rec, 0 ctls audio0 at uaudio0 ugen0 at uhub1 port 2 configuration 1 "JDS Labs JDS Labs Atom DAC+" rev 2.00/2.12 addr 2 uhidev0 at uhub0 port 2 configuration 1 interface 0 "OZU OZU8" rev 1.10/0.01 addr 2 uhidev0: iclass 3/0, 3 report ids ukbd0 at uhidev0 reportid 1: 14 variable keys, 0 key codes wskbd0 at ukbd0 mux 1 ucc0 at uhidev0 reportid 3: 8 usages, 8 keys, enum wskbd1 at ucc0 mux 1 On the OZU8, volume dial (clockwise for volume up, counter for down) has no effect on sndiod. (and I checked that from a terminal, $ sndioctl output.level=-0.5 reduces audible volume as expected) There are many internet descriptions of how to configure devices that are 'uhidN', with use of 'usbhidaction' But I am having trouble finding advice for situations with wskbd0 at ukbd0 at uhidev0 wskbd1 at ucc0 at uhidev0 $ wsconsctl shows information for keyboard* keyboard1.* for keyboard1, which I am guessing is wskbd1 at ucc0 $ wsconsctl keyboard1.map keyboard1.map= keycode 0 = AudioRaise keycode 1 = AudioLower keycode 2 = unknown_0 keycode 3 = AudioMute keycode 4 = unknown_0 keycode 5 = unknown_0 keycode 6 = unknown_0 keycode 7 = unknown_0 which seems like this device (volume 'dial' raise/lower, buttons 'prev', 'play/pause', 'next') $ wsconsctl keyboard.map has 236 keycodes though I do not have any USB keyboard attached at all Thank you.
