I am running into troubles here. After reboot, the

haywire!? And I have not even done any changes to the system yet ...
At first, I reboot with the usb device off and then have a peek:
$ ls /dev/midi*
/dev/midi1
$ amidi -l
Device Name
hw:1,0 MPU-401 MIDI 1-0
.. which looks as expected. But then turning the device on gets weired:
$ amidi -l
Device Name
hw:1,0 MPU-401 MIDI 1-0
ls /dev/midi*
/dev/midi /dev/midi1 /dev/midi2 /dev/midi3
.. which is no good. The /dev/midi* devices are too many and not
working.
It seems the usb-midi driver grabbed the device first. Disable it in
the kernel configuration, or put the line
usb-midi
into the /etc/hotplug/blacklist file.
