USB Sound Card won't install.

Hi there, I bought a Steelseries USB Sound card about a week ago and only got around to installing it, except from it won't install.

When trying to install the card, it would come out that it's not connected when it is and I'm not sure how to fix this error.
I've tried two different drivers from the company and they both come up with the same error.


I've tried Uninstalling it, unplugging device, restarting and plugging it back in.
I've tried disabling the automatic driver search and installing.
I've updated my drivers (except BIOS).
I've tried using two different drivers.
I've tried Every spare USB port in my computer.
I've tried installing it with the Headset in the sound card and without.
I've tried Disabling all the other sound cards in my computer.
I've tried Uninstalling all the other sound cards in my computer.
I've tried installing it in safe mode.
I've google'd up some fixes but none work even silly things like restarting my computer 5 times.

All to no avail, everytime it comes up with the same message.

The adapter does install by windows into a "USB PnP Sound Device" which would make you think It'll work but it doesn't.
For that reason, I know it isn't the cable and it is finding it but won't install it for some reason.

I had a similar problem with a internal sound card before but in the end had to RMA it, hopefully I won't have to do that especially in the middle of the Christmas holidays.

Has anyone else had this problem or have any ideas how to fix it?
