No mic sound through lexicon alpha

time to turn to the community again.

i am trying to record ann acoustic guitar into garageband. if i allow the internal mic to record things it picks up the track and it can work. unfortunately i have a mic with phantom power running through a lexicon alpha that i would like to use as the quality would be much better.

this is where i am at. under preferences in garageband i go to the audio/midi tab and it shows the lexicon as the in and out source. on the garageband page itself it shows the lexicon as the input source. monitor can be off or on. unfortunately the recording level is grayed out all the way to the left. seems like the problem.

so i went to the utilities folder on the mac itself. audio midi setup. it shows under audio devices built in microphone, built in input, built in output, and lexicon alpha in/out 2in/2out. in this window i cannot adjust the volume level either. it has channel m,1, and 2, all pushed to the left. when i click on it, it appears to be 'grayed out' also. also, when i unplug the usb cord the mac realizes it instantly in garageband and asks if i want to switch to built in audio. so it knows it is there.

all of the pots on the front of the alpha are at 3 o'clock. when i plug in headphones, i can hear the guitar sound clearly it just is not getting from the alpha through the usb cable into garageband. i know it is probably an easy fix i just cannot figure out what i have checked/unchecked to cause this.

any and all wisdom is apreciated.
