This is done in the professional world by having audio card driver software present the software with the multitude of inputs even though it is across multiple cards (typically when you are recording 20+ analog inputs) Or you will need to 'mix' them down to a single device, then the software will have no problems. I assume that when you say 'make 2 USB headsets work on the same computer at the same time' you are referring to having both of them send and receive the same audio at the same time.Įither you need to find software that will support multiple recording devices at the same time. And most recording software will only use 1 recording device and 1 playback device. One key technicality that defines all this: each usb device will show up as a separate audio device. The only restriction Windows has with this is that you can only assign 1 default recording device and 1 default playback device. you can even have both playing through the speakers at the same time, it will even support having multiple audio out devices functioning at the same time.
Windows7 has no problem having multiple microphones working on the same system. You say that windows is the issue, but it really depends on what you are trying to get out of the usb headsets. Tough windows is the issue not allowing both headsets to work
