I didn't read it completely myself, since I've got my own issues to
solve, but perhaps it's related, even if it's an USB device here:

Hi,
I have a Presonus AudioBox 44VSL that is failing with bad descriptors:
[ 246.649802] usbaudio: unit 51: unexpected type 0x09
[ 246.649859] snd-usb-audio: probe of 2-1.2:1.0 failed with error -5
This seems to be a problem people have had with other devices and with
some
help in #alsa I have made the attached patch that
fixes the problem.
More details of the device and errors in this thread:
http://linuxmusicians.com/viewtopic.php?f=6&t=7738
This is fixed in 3.9-rc4 and newer kernels, and the fix will also be
included in the next Ubuntu Quantal kernel update.
See the recent "ALSA and SCARLETT FOCUSRITE 8i6" thread for details.
