Output Device Inactive

Hi, I’m using an Akia EIE and I’ve gotten the inputs working in Cubase LE 5 however I am wanting to use my Microsoft Lifechat headset as the default output device and when I go to Device Setup/VST Audio my headset is showing up but is inactive. How can I map the audio output of Cubase to my headset?

What ASIO driver?

ASIO4ALL v2

Connections in Device setup show as inactive, as long as they are not connected to a Cubase bus in VST connections.
