What are you using mac or Windows? Add a signature with the basics of your setup please.
What you want is in principle not possible because you're using an ASIO driver, this driver doesn't allow 2 or more soundcards to be active. The USB mic can/must be seen as a (2nd) soundcard!
For Windows you could try ASIO4ALL, for mac maybe agregated devices.
I'm not a mac user so if others could fill in at this point would be nice.
