Microphone is not detected at all!

I purchased an Audiogram 6 and it came with Cubase AI 5.

I plugged it in and it picks up the headphones I have in the Audiogram, and so plays all sound through them.

But my microphone is not detected at all!

When I check the list of inputs, it only has the computer’s in built mic listed.

Even though the output has the speakers (USB Audio Codec) listed!

Any help would be greatly appreciated, thank you.
