USB midi keyboard not detected

What I do: Plug in my M-audio Oxygen49 keyboard.

What I expect: It to show up in Helvum, appear in `aconnect -i` etc

What actually happens: The device is shown in lsusb, dmesg doesnt show any errors, yet isnt recognized in aconnect.

aconnect -i
client 0: 'System' [type=kernel]
    0 'Timer           '
    1 'Announce        '
client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'

A forum thread from 2017 seems to have the same problem: https://bbs.archlinux.org/viewtopic.php?id=226006

A member of the unofficial arch linux community discord also seems to have had the same problem: https://discord.com/channels/3998125519 … 4622444594

rn, i suspect this is a kernal issue, but not sure where to look for more information. The wiki seems to be out of date

https://wiki.archlinux.org/title/USB_MIDI_keyboards

the kernal modules usb_midi, etc, dont seem to exist anymore. Last major edits of the article were 2015 so it makes sense that its not working
