Yamaha DGX-205 Keyboard & Linux usb-midi

I have this keyboard which has a USB interface instead of standard MIDI
ports. I've used the usb driver under windws and it provides standard midi
functionality (works with cakewalk), and also gives access to some flash
memory for storing midi/GX files into the keyboards memory.

I would like to hook this keyboard up to Linux and send information to it
via pmidi/playmidi and/or access the flash memory. I am using and HP
Pavillion laptop with Mandrake 10, with a 2.6.7 kernel, patched with the
latest stable alsa drivers (1.0.5a).

I connect the keyboard and type:
modprobe usb-midi, which produces this in the syslog file:

Aug 14 23:00:31 voodoolinux kernel: usb-midi: Found YAMAHA USB-MIDI device

Aug 14 23:00:31 voodoolinux kernel: usbcore: registered new driver midi

and modprobe snd-usb-audio:

Aug 14 23:01:03 voodoolinux kernel: usbcore: registered new driver
snd-usb-audio

This adds a new /dev/midi device which is linked to /dev/sound/midi

However, there doesn't seem to be any way to use this device using the
alsa/midi tools I'm familiar with.

I try typing pmidi -l, and it shows no available ports

Looking at /proc/asound/devices, only shows the built-in sound card

Are there any other modules I need to load to get alsa and the sound
utilites to identify this keyboard as a usable midi device? when I run
harddrake2 (a mandrake utiltity which lists hardware devices), the keyboard
has an entry in the "scanner" devices under port libusb:001:005, but there
is also a reference to it in the "unkown" devices as well.

If it's not supported by Linux, I'll just switch to windows temporarily as
needed, but I want to make sure that I am not doing anything wrong. If
someone out there is familiar with usb midi devices under Linux, I would
appreciate hearing how it's supposed to work.

I have a 2nd machine which has a sound-blaster live card, and I have been
able to use alsa/pmidi to send midi information to send songs to an
external keyboard connected to the joystick port using midi cables.
        
in case it's helpful, lsusb -v shows this information:
