Not sure if I'm seeing the same problem, but it sounds like it might be.
My midi controller (keystation) works fine for day after day of minimal
use, and then one day I'll go to use it and it doesn't work. qjackctl
sees it and can establish connections, dmesg reports nothing unusual. It
just doesn't seem to be generating any events. I unplug its usb and it
disappears from qjackctl. I plug it back in and it reappears, but still
doesn't work. So I unplug the power and plug it back in, same thing. So
I unload snd-usb-audio and unplug the usb and plug it back in and the
same thing. Finally I give up and reboot.
Yesterday after rebooting, it still didn't work, so I unplugged all my
USB devices (keyboard, mouse, scanner, keystation) and plugged the
keystation back in, and then it worked.
Very frustrating and since dmesg doesn't say anything interesting and
afaict alsa things it's fine, I don't know where to look for more
information.
2.6.13-rt13, and the problem has been around for ages.

There's nothing remarkable about it. All one has to do is hit the
right keys at the right time and the instrument plays itself.

Hi,
2.6.14 works great here.
BTW upgrading your ALSA modules is not enough to fix this bug - since
the bug was in the USB subsystem the kernel must be upgraded. Kernel: 2.6.11-0.3rdt.rhfc3.ccrma
Alsa version: 1.0.9rc1
thanks for the info.
At least it appears that the bug is solved. I hesitate to update the
kernel, because the last time it caused *lots* of troubles on my
machine.
Still dreaming about a stock kernel being perfect for audio use :) .
