I'm trying to get my Roland UM-2 usb to midi interface working on the
2.6.4 kernel. I have the kernels usb midi and usb audio turned off. The
alsa usb audio driver is a module.
I can access the device via /dev/midi01 meaning if I cat a midi file the
lights on the interface blink.
What I can't do is have Alsa see it. I would like to be able to use this
device under rosegarden or pmidi .
Any ideas as to what I'm doing wrong.

The /dev/midi0X files are for raw MIDI data. To play midi files, use
some program like aplaymidi or playmidi or pmidi.

Strange. Is the snd-seq-midi module loaded?
Do the UM-2's ports appear in /proc/asound/UM2/midi0?
In /proc/asound/seq/clients?
In the output of "aplaymidi -l"?
