Microphone doesn't work with my interface


I own a Steinberg UR12 interface, the headphones are working when i am connected to my interface but if i plug in my microphone it doesn’t want to record anything. It just doesn’t work at all.
I installed the including CD for the usb drive installation, and my computer recordnizes the interface, the microphone and the headphones. I don’t know where the problem is. My microphone isn’t broken because it’s brand new and it should work, could somebody help me please? :confused:

What microphone is it?
