I booted OpenBSD 4.8 on that machine to see what it had to say about the SD-20. tingo@home99$ uname -a OpenBSD home99.kg4.no 4.8 GENERIC.MP#359 i386 tingo@home99$ usbdevs -dv -f /dev/usb0 -a 4 Controller /dev/usb0: addr 4: full speed, power 500 mA, config 1, EDIROL SD-20(0x0027), Roland(0x0582), rev 1.00 umidi1 tingo@home99$ tail -7 /var/log/messages Feb 23 00:30:15 home99 /bsd: umidi1 at uhub2 Feb 23 00:30:15 home99 /bsd: port 3 configuration 1 interface 0 "Roland EDIROL SD-20" rev 1.10/1.00 addr 4 Feb 23 00:30:15 home99 /bsd: umidi1: (Fixed Endpoint) Feb 23 00:30:15 home99 /bsd: umidi1: out=2, in=3 Feb 23 00:30:15 home99 /bsd: midi1 at umidi1: <USB MIDI I/F> Feb 23 00:30:15 home99 /bsd: midi2 at umidi1: <USB MIDI I/F> Feb 23 00:30:15 home99 /bsd: midi3 at umidi1: <USB MIDI I/F> Interesting, it seems it uses the umidi(4) driver, not the snd_uaudio driver under OpenBSD. -- Torfinn
