OT: How to set up a USB microphone

[admin]

I recently acquired a Zoom H2 portable recorder which according to the docs should work as a USB microphone, and I have no doubts it does. But, uhm, where do I define it as audio input device? Anybody here happens to know? (Yep, I need it for the videos.)

Ok, microphone's working now. Unfortunately the otherwise perfect Wink software produces an extremely compressed sound stream with very bad quality. So, no voice over nor music for now.
