But then again, it attaches like this on FreeBSD:
ugen0.6: <M-Audio Fast Track Ultra 8R> at usbus0
uaudio0 on uhub2
uaudio0: <M-Audio Fast Track Ultra 8R, class 239/2, rev 2.00/1.51, addr 6> on
usbus0
uaudio0: Play[0]: 96000 Hz, 8 ch, 24-bit S-LE PCM format, 2x4ms buffer.

uaudio0: Play[0]: 88200 Hz, 8 ch, 24-bit S-LE PCM format, 2x4ms buffer.
uaudio0: Play[0]: 48000 Hz, 8 ch, 24-bit S-LE PCM format, 2x4ms buffer.
uaudio0: Play[0]: 44100 Hz, 8 ch, 24-bit S-LE PCM format, 2x4ms buffer.

uaudio0: Record[0]: 88200 Hz, 8 ch, 24-bit S-LE PCM format, 2x4ms buffer.
uaudio0: Record[0]: 48000 Hz, 8 ch, 24-bit S-LE PCM format, 2x4ms buffer.
uaudio0: Record[0]: 44100 Hz, 8 ch, 24-bit S-LE PCM format, 2x4ms buffer.
uaudio0: Single command MIDI quirk enabled
uaudio0: MIDI sequencer.
pcm3 on uaudio0
uaudio0: No HID volume keys found.
But according to wiki, class 0xef (= 239) is "miscelaneous",
i.e. not audio, which is 0x01, so I still don't believe
it is a class-compliant device ...
