I finally (with lots of help from you - thanks!) got the new usb stack
installed. And this includes the USB MIDI driver, I guess.

I also installed the libumidi20 and QT4 / midistudio.

I couldn't find a '*umidi*' module in /boot/kernel, or anywhere else
for that matter. So I'll need a little help here.

I have two usb midi devices, a keyboard and a sound / effects module the show up as:
Sep 21 08:34:36 kg-quiet kernel: ugen0: <Evolution Electronics Ltd. USB MIDI keyboard, class 0/0, rev 1.00/2.52, addr 126>
Sep 21 08:34:24 kg-quiet kernel: ugen1: <Roland EDIROL SD-20, class 255/0, rev 1.10/1.00, addr 126>

usbdevs -v:
root at kg-quiet# usbdevs -v
Controller /dev/usb0:
addr 126: full speed, power 500 mA, config 1, EDIROL SD-20(0x0027), Roland(0x0582), rev 1.00

Controller /dev/usb2:

 port 3 powered
 port 4 powered
 port 5 powered
 port 6 powered
 port 7 powered
 port 8 powered

and there are no /dev/umidi* to bee seen.
Should the /dev/umidi* be created when these devices are attached? Or do I need to kldload a module first?

I have tried to start midistudio, both as my normal user and root, but it doesn't seem to create /dev/umidi* either.
I am running
