asterisk users - Jan 2009 - asterisk support for multiply (two) console dsp devices

Is it possible for asterisk to support multiple USB  audio devices 
independently as Console/Dsp???

At the moment a call comes in and routes to Console/Dsp which is the 
sound card on the motherboard.
What if I needed another audio device so I added a second or third USB 
audio device. How do I
set up asterisk to route sound to the desired card?

Thanks,

Jerry
