Yamaha PSR-EW300 USB MIDI Keyboard not showing up in Haiku

This is a very niche issue and truthfully it isn't even the highest priority on my end, but having my keyboard show up on Haiku and be available to use as a sound output would be amazing. I use it almost exclusively to output audio from, since the speakers included sound miles better than the built-in ones on my Dell prebuilt.

The title says MIDI keyboard, but it sounds like you are using it as an audio out device, not a MIDI out device?

Isn't it recognized at all? You could do a "tail -f /var/log/syslog" and plug in the keyboard and see whats printed out. It should also show up in the app "Patch Bay".
