the hardware you posted is crap, I have the same thing with me here, just ordered it a few weeks ago, the hardware I got (manufacturer Commdow) did not contain the driver CD, I downloaded and installed it, the hardware worked for some time (the sound was lousy) and them completely stopped working. Now whenever I plug in the device I get a message 'usb device caused malfunction..etc..)
If you have to buy something get it from a reputable manufacturer like Soundblaster, there is another company that makes this here is the link **broken link removed**
I should have bought from them...
