I am considering replacing my aging Logitech 5.1 speakers which are connected to the MB's on board audio with a set of 2.1's. The replacements I am looking at are connected by USB. I also use the Corsair HS1's (freaking awesome BTW) for gaming, which are also USB. I have no problems plugging the headset in now, however will there be an issue with having 2 USB audio devices connected at once?
