Subject: [linux-audio-user] USB midi Setup
From: Elias Kesh (P) ("Elias)

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.
