I bought some new Logitech headphones that has a USB 2.0 male connector to my PC. I can't figure out how to make the headphones use my soundcard instead of the audio drivers included on the headphones. What I'm looking for is a cable with female USB 2.0 that ends with the 3.5 jacks for both headphones and mic. I've found USB to 3.5, but just one 3.5. Any help?
