CUBASE 4 VST

I am using CREATIVE SB for ASIO OUTPUT on CUBASE 4 My problem is that when i select Audio Soundblaster USB Audio it is not reading but reads ASIO SOUNDBLASTER COULD NOT BE LOADED…Ive also tried both multimedia driver and directx full duplex
The SB driver is loaded and visible in the sound and audio devices properties.

Ive tried all that i know to resolve problem but cant.
