Cubase 6 Elem - PV6 mixer - Interfacing

I just bought Cubase 6 Elements, a set of pevey drum mics, and a Peavey PV6-USB Mixer. The Mics and mixer are working properly. I would like to know know how to properly hook up the Mixer and Cubase. So far I can get Cubase to record some sound with a lot of extra noise.

Which ASIO driver is selected?
