Could you tell me what driver you're using for the um1? I tried 'usbmidi-20020122.tar.gz' from member.nifty.jp/Breeze, but I couldn't make it work...either on red hat 7.2 or debian 2.2.r4...I think I probably missed something obvious, though. Any advice on the install?
I'm using usbmidi-20011212. W/ kernel 2.4.5, debian/unstable.
ls -l /dev/midi0 crw-rw-rw- 1 root audio 14
After I connect the UM1 I type 'modprobe usb-midi'.
That should be all you have to do.
