Yamaha MG12XU CubaseAI 7 init problem

Hi there. This is my first time posting here. I bought a MG12XU. I’ve installed latest 1.9.0 from 9/24/2014 drivers.
So plugged in usb cable to pc, turned on mixer, launched Cubase AI 7, select MG12XU ASIO driver and then… Nothing happens. It stays there forever.
Can anyone give me some help?

PC is a HP Pavilion DV6, Intel I3, Windows 7 Home Premium, nothing on the USB ports, just a brand new MG12XU.
