[Alsa-user] Korg Triton Extreme USB MIDI interface

Hi all,
I've looked in the mailing list archives for something related
to this, but I've been unsuccessful so far. If, as the case
may be, I've simply overlooked the answer, please just point
me in the right direction.
Here's my problem:
I just got a Korg Triton Extreme. The EX has a usb interface
on it that allows storage and MIDI access to the device from
a host PC. I can't seem to get ALSA to recognize it as
a MIDI interface. For the record, in case someone comes
across this message via search engine: The usb-storage
works fine. Make sure you put your Triton EX into "usb
storage mode" from the Media Utilities menu. (It must
have exclusive access to avoid data corruption.)
I'm using PlanetCCRMA on top of Fedora Core 1, everything
is up to date, as far as apt-get dist-upgrade will allow.
In /var/log/messages I get the following when I plug in
the device:
Jun 29 21:31:42 daw kernel: usb.c: USB device 2 (vend/prod 0x944/0x10) is
not claimed by any active driver.
And if I "modprobe usb-midi" by hand I get:
Jun 29 17:30:57 daw kernel: hub.c: new USB device 00:07.3-1, assigned
address 26
Jun 29 17:30:57 daw kernel: usb-midi: Found MIDISTREAMING on dev 0944:0010,
iface 1
Jun 29 17:30:57 daw kernel: usb-midi: Found MIDIStreaming device
corresponding to Release 1.00 of spec.

Jun 29 17:30:57 daw kernel: usb-midi: Found OUT Jack 0x30 EMBEDDED, 1 pins
Jun 29 17:30:57 daw kernel: usb-midi: Found IN Jack 0x20 EXTERNAL
Jun 29 17:30:57 daw kernel: usb-midi: fetchString(2)
Jun 29 17:30:57 daw kernel: usb-midi: fetchString = 14
Jun 29 17:30:57 daw kernel: usbmidi: found [ TRITON Extreme ]
(0x0944:0x0010), attached:
Jun 29 17:30:57 daw kernel: usbmidi: /dev/midi01: in (ep:84 cid: 0 bufsiz:
0) out (ep:03 cid: 0 bufsiz:64)
So the OSS driver recognizes it as a legitimate MIDI streaming device.
How do I get ALSA to claim "0x944/0x10" and attach snd-usb-audio to it?
I'm sure this is the key.
I appreciate any help you can give me on this.
I'll include some informational output below, but feel free to ask
if you need something else to help me:
