2.0.0 configuration

Recently switched to Linux and cannot seem to get my external mic recognized and actually need a step by step set up if one is available.

What sort of Mic?
How does the mic connect to the computer?
Which Linux distribution?

Ubuntu 12.04
CO1U Samson

Connect your mic and allow your computer a minute to recognise it before you open Audacity.
Then open Audacity and look in the recording input device box in the Device Toolbar and select the USB option.
