I know that the US-144 MKII has a different Product ID (8020) than the US-144 (800F), so the US-122 MKII probably also has another one than the US-122L. If you post your output of lsusb with the device plugged in, I could make a patch that adds these both IDs to the us122l driver for testing if that suffices.
I don't know if you are familiar with compiling kernel modules etc. If you need more detailed instructions, you can join the discussion at http://forum.ubuntuusers.de/topic/tascam-us-144 in either German or English (I know desy.de doesn't necessarily mean you speak German) or send a mail.
By the way, I suspect the "linux specialist" at that shop is good in making things up, because Tascam has never provided any Linux drivers and he can't really know what the Linux people do on their own.
Best regards, Tobias Hansen
