It doesn't seem to finish initialization. Could you reboot, disable uaudio(4) device driver (at the "boot>" prompt type "boot -c", then "disable uaudio", then "quit") This will make the RME Babyface Pro attach ugen(4) devices instead of uaudio(4) and umidi(4) ones. Then download this program: https://caoua.org/ugendesc.tar.gz and do: tar -xzvf ugendesc.tar.gz cd ugendesc make For each of the ugen(4) device that show up in your dmesg output run: doas ./ugendesc /dev/ugen0.00 >/tmp/rme_baby_face0.txt doas ./ugendesc /dev/ugen1.00 >/tmp/rme_baby_face1.txt ... This utility dumps the USB descriptos of the device in a format that allows me to test and debug significant parts of the uaudio(4) driver without access to the hardware. thanks
