I think that has been done... looking at kernl 2.6.5-rc1 i find:
<perex(a)suse.cz>
ALSA CVS update - Clemens Ladisch <clemens(a)ladisch.de>
USB generic driver
- fix non-working control port on Roland U-8
- more port names
- new MIDI quirks for Roland MMP-2, V-SYNTH, VariOS, FP-*, GI-20,
BOSS GS-10, Edirol UR-80, PCR-A, PCR-1
So maybe its already done.

The MIDI port should be supported since ALSA 1.0.7.
PCM playback/recording probably won't work, but I can add a quirk to
the driver if you send me the "lsusb -v" output for each position of
the "sample rate" switch.
