Corsair vengeance 1500 detected as speakers and no sound

Hi,



I recently purchased a brand new corsair vengeance 1500 USB headphones. Sadly, my laptop( running a windows 7 OS) is detecting my headphones as speakers. Ive installed the software program yet it still did not work. On top of that, i cant hear anything nor use the mic. I also cant set it as a default device under the sound manager.



Please help!!!
