Does this headset come with an Usb Adapter?
I recently got this headset as a christams gift, and it works great. Exepct the mic, my computer does not recognize it. Does this headset come with an usb adapter as i did not get one, im using it trough the headphone and mic jack on my computer. The sound part is great but the mic doesnt work. When i plug in the mic my friends cant hear me.
