USB mic not recognized input source?

I have Audacity 2.0.3 installed on a MacBook Pro operating 10.8.2
I’m trying to use a USB mic C-1U that doesn’t seem to be recognized by my computer.
Manual says my operating system should automatically install drivers - nothing happens when I plug mic into USB port.
I can record in Audacity without mic, but when I select use USB mic input and hit record, error message: “Error while opening sound device. Please check the input device settings and the project sample rate.”

see this FAQ:


Macs don’t need the big fuss of loading drivers. Your microphone should just be there. Plug in the mic and give the computer a second to chew on it, then launch Audacity. Does that mic have any lights on the front? Do they light up?
