M-Audio Transit / madfuload stopped working with Kernel >3.4

[sharkus]

After upgrading to Kernel 3.7 my USB-soundcard doesn't seem to be recognized anymore. It is an old M-Audio Transit. I recompiled the firmware loader

Code: Select all

media-sound/madfuload

from portage but it still doesn't work. I didn't make any changes in alsa.conf or elsewhere. When I switch to the older kernel it works like charm.

After connecting it, /var/log/messages outputs:

Code: Select all

Is anyone else here using a soundcard with the madfuload firmware loader or has some tips for solving the problem?
