Hi, that sounds promising.
I have the UCX running in CC mode, and I also see it in the Alsamixer with only one
control, the master volume.
so that part isn't the problem.
the fix of the alsa /sound/usb/mixer.c is in kernel 3.8 which i have on the system.
however: If i select this device in some alsa software i get horrible crackles (I tried
44100 and 48000 Hz, they both give me different kind of crackles).
What do you do to get useful sound out of it?

I use the ff ucx via USB. As far as I know, it is not possible to use it via firewire.
I getting reasonable sound results using the usb class compliance mode, you have to make
sure that this mode is enabled on the device (it is NOT by default).
The ALSA driver then recognizes the device. If you enter
in a terminal, you get a list with all devices available to alsa. If it does not appear
there, try the comand
to look for error messages of the alsa kernel module. If I do that, I find a message
usbcore: registered new interface driver snd-usb-audio
indicating that the interface is working. Then, the device is available in pulse-audio
and also jack, you can choose it there.
I should add the following: My system (and in particular the alsa kernel module) is not
up to date. I am still using an old customized version, where I fixed a bug by hand
(getting help from the alsa list). As far as I remember, this bug was fixed so that the
device should work with the standard alsa kernel module. However, I never tested it, maybe
I find time to do that during the weekend.
