there it should be US-122L ... that's really strange.
are you really sure you plugged a US122L ? just to be 200% sure :)

and after that you should have : 

   kernel: usbcore: registered new interface driver snd-usb-us122l

you can test it with the following (as root)

~]# lsmod | grep snd_usb_us122l
snd_usb_us122l         18144  0 
snd_usb_lib            19600  1 snd_usb_us122l
snd_hwdep               9816  2 snd_usb_us122l,snd_hda_codec
snd                    74824  10

if it's not here then :

] modprobe snd_usb_us122l

you should see the trace in /var/log/messages.

You problem  clearly comes from the US-144 device detected ( not
US-122L) . As you can see here :
http://www.alsa-project.org/main/index.php/Matrix:Vendor-Tascam , US-144
does not appear in the list of supported devices...

hope that helps.
