I'm trying to get my Tascam US-122 USB audio interface working with Ubuntu 12.10 based on the "Installation (newer releases)" instructions at :

https://help.ubuntu.com/community/TASCAM_US-122

At Step 2, I was able to find and install the
alsa-firmware-1.0.25.tar.bz2

But at Step 7, when I sudo usx2yloader

I get the error : No USX2Y-compatible cards found

I tried the suggested fix :

sudo ln -s /usr/share/alsa/firmware/usx2yloader /lib/firmware/usx2yloader

but get the same error. Any ideas?
