Apple Logic Pro /LogicExpress Discussion

Hello:
I'm working on a new station, a G4 tower with 10.3.9 OS X.  I am attempting to run a 
Tascam US-122 USB Audio/MIDI interface.  I can't get logic to recognize the interface.  I go 
into:  Audio:  Audio Preferences: Audio Driver and the only option I get is built in audio or 
no driver.

Can somebody help me out?  What can I do to get Logic to search for or recognize the 
interface?  It's been a while since I tried to install; there's not something I'm missing as far 
as installing logic or additional support software that would keep me from capturing the 
interface is there?

I have the USB input for the Tascam going direct into the tower, instead of through a 
multi-port USB hub, but that's not helping either.

Any advice would be greatly appreciated.  Thanks!

Aaron
