Hi Takashi,
I have almost the same problem as Marco. (that is why Marco forwarded me this message).
Well, Now it seems to be almost perfect. Just to explain to you :
I had a problem with Pure data, each time I wanted to enable the alsa midi (in pure data). Then I had some problem opening some of my patch, making pd zombified and Jack output tons of "delay of 1666.000 usecs exceeds estimated spare time of 1140.000; restart ..." until I stop it and run it again.
Now pd works perfectly. I made some others jackd settings, and the "xruns" messages seems to gone away.
But like Marco I got this message in the output of dmesg :
[ 20.269196] Adding 530136k swap on /dev/sda3.

Thank you for your help and your great job. I can use pd now, my main software to make music. So I am very happy :)
Just a thing, when I press the buttons on the top of the Audio Kontrol 1 I got qbc (azerty keyboard). but When I move the jog, the system log out.
Did anyone find a way to change the assignation of these buttons ?
Kind regards,

The "rawmidi drain error" went away. Now if I start and shut down jackd nothing bad happens. But when I launch Rosegarden there are several lines containing the following new message:
[ 455.025168] ALSA /home/marco/build/linux-2.6.24-19-rt/alsa-1.0.17/driver-patched/alsa-driver-1.0.17/usb/caiaq/../../alsa-kernel/usb/caiaq/caiaq-midi.c:84: snd-usb-caiaq log: snd_usb_caiaq_midi_send(f76a5ac0): usb_submit_urb() failed, -22
Furthermore the first time I rebooted my system, it freezed during the startup procedure (loading hardware drivers), but it didn't happen again.

I applied the patch (or I think so...). I just removed the line:
dev->midi_out_substream = NULL;
from the function snd_usb_caiaq_midi_output_done in the file
caiaq-midi.c.
Then I recompiled the driver.
The main issue is sorted out: I can start and shut down jackd without
big
problems.
But with dmesg I still have the following message:
ALSA /home/marco/build/linux-2.6.24-19-rt/alsa-1.0.17/driver-patched/ alsa-driver-1.0.17/acore/rawmidi.c:196: rawmidi drain error (avail =
4095,
buffer_size = 4096)
Not sure if it is safe to ignore it.
Hmm, what about the patch below?
