I have 2 Xbox 360 consoles, both with the Zephyr motherboard. I have a standard wired headset that works just fine with one console and controller. But when I swap out that console for my second one (using the same controller, headset and the same wired network plug), the headset does NOT work. What is up with THAT? How would that work exactly? Is there some hardware in the one Xbox that could be defective?
