I have virtually the identical problem. AU Lab will output audio to my MacBook Pro built-in output (laptop speakers), but will not send output to my UX2 audio interface.
I'm using Soundflower as a virtual input as well.

Same problem here: Soundflower-Input and AU-Lab Output not working if assigned to Nubert nuPro A-20 internal USB audio interface. Works fine with integrated iMac audio.

Fixed it: When switching output to USB device, the input channels changed as well. Manually moving (click & drag) inputs to "Soundflower Input Stream #1" worked for me.

Click and Drag, eh? How do you do that? I've got the same problem.

In my case, the following steps worked:
1. setup new document with routing "Soundflower (2ch)" to "Output (integrated)"
2. show the "Studio" drawer from Window menu
3. select usb audio as output (in my case called "UAC35568")
After step 3, the soundflower input did not work any more. Instead of "Soundflower Input Stream #1" the channels 1 & 2 called "Stream 1" were selected.
4. Click the red input channel bar and drag it to channels 3 & 4 "Soundflower Input Stream #1" ("Soundfl...tream #1" in the image)
After changing the input channels, everything worked fine for me.
Here is a screenshot of how it looks in the end:

I'm not as smart as you but really nice directions! I'm trying to output AU Lab thru USB to my Lexicon Alpha and I can get sound through both the Alpha and the onboard iMac speakers but the eq only effects the onboard speakers.
I'm really only trying to get a global bass boost (much like the old loudness button) when I'm listening at low volume.
Any ideas would be helpful and sorry to be a pita to you all!
