MOTU Interface Issue: Audio Not Reading In Host Software

Question

Greetings. I'm in need of help. I'm using my MacBook Pro for live studio recording and it receives audio from a MOTU UltraLite Mk3 Hybrid Interface via Firewire cable.
The Audio Reads in the System Preferences Sound Input Level Monitor But Not in Host Software.
Although the audio signal from my mixer is making it to the interface (can see levels)and the audio from the interface is making it to the computer (can see on system preferences "Sound" input level monitor)it is not being read on any host software I've tried which includes: AudioDesk 3.02, Garageband, Cubase 4.1, Audacity, and Adobe SoundBooth CS3.
Note: Output (for playback) is set to go through the MOTU Interface and works well.
Here's an Overview of the machine's Hardware:
Model Name: MacBook Pro
Model Identifier: MacBookPro4,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB
Memory: 3 GB
Bus Speed: 800 MHz
Boot ROM Version: MBP41.00C1.B03
SMC Version (system): 1.27f3
Serial Number (system): W8*
Hardware UUID: 21BCA47D
Sudden Motion Sensor:
State: Enabled
Any advice is greatly appreciated. But please note that I've followed all instructions provided by Apple, MOTU, and all set-up instructions for host software and I've also disconnected the MOTU interface and recorded directly into the MBP and it worked fine.

Well, it's nearly 2 years later... and this part of the problem mentioned in the link you provided is exactly what I'm experiencing!
Yea it is rather interesting from a couple of perspectives. One being that MOTU seems to be pretty diligent about their products and compatibility issues (just from reading through their "Tech Notes" at http://www.motu.com/techsupport/technotes.html). Also, I found that if you go to one of their product pages like "UltraLite-mk3 Hybrid Overview" (http://www.motu.com/products/motuaudio/ultralite-mk3) you can then click on the Tech Notes link (http://www.motu.com/products/motuaudio/ultralite-mk3/technotes.html)and that will narrow the results to Tech Notes that mention that specific product.
Researching off the tech notes and the info you provided, I did find other users with similar problems, but nothing really as conclusive as the link I suggested in the previous post. Also, of note, is that reading trough some of the search results, I realized the "whole ball of wax" can get quite complicated and goes well beyond my knowledge of the issue and the technology involved.
All that being said, have you tried contacting MOTU's tech support (http://www.motu.com/techsupport/)? Just by their documentation, they seem to be on the ball - might even have a ready answer. Like any vendor, they may have specific issues that they have not heard or dealt with before, but their website structure and content does seem to suggest they take an interest in getting their products to work across a myriad of tech environments and use cases.
Hope this helps.
