Hi there guys. I have a lenovo y50-70, and it has the combo input. I am using as a main headset a razer kraken 7.1 v2, that has an usb. Recently bought a studio mic with a 3.5mm jack with 2 rings on it. When i try to connect it, it doesnt show up. I have an usb adapter, but all my usb ports are used, and i dont want to use a usb hub. Any ideas how to use it with the combo input?
