RecordInput Setting for Telex USB Audio Device

[Sannyasin Sivakatirswami]

Is there any way to query the system on OSX for the 4 character string 
that will automatically switch the record input property to a setting 
that will pipe the sound from USB input?

Of course one can go to the sound control panel in system prefs, set 
the input to the "Telex USB Audio Device" (excellent! piece of hardware 
by the way... comes with iListen...) and then in the record scripts, 
set the recordInput to "dflt" and it works... And happily it seems even 
if the  user has his system sound prefs set to internal Mic... when he 
plugs in the Telex USB into the USB port the sound panel seems to 
recognize this and automatically switches to the USB -- so that (set 
the recordInput to "dflt")  works.

But I have been "burned" too many times when you think everything is 
going work and then in a live recording situation, defaults all sudden 
change... then the user will simply gets no sound file recorded.

  I would rather hard code the USB into the recordinput Property in my 
scripts. I tried all the ones listed in the docs imic, emic, mbay, idav 
etc... none of them work, only dlft works if USB is already set in the 
system sound prefs. Is this list of 4 character options hard coded in 
the Metacard engine? or are they part of Quicktime? If the latter, I 
would assume one could read them somewhere...
