cubase and bose companion 5 issue:no output

Hi,
i am a newbie of cubase and i found this issue when i setup the tool. I have a notebook and a bose companion 5 usb audio but cubase only works with standard notebook output and mic.
Officially bose companion 5 has a windows generic driver but if i go in

Devices - devices setup -VST Audio System i only find generic low ltency ASIO Driver .
Suggestions?

thanks in advance
