The first time you plug in the autore, your device needs to recognize it. This can take a few minutes. We recommend waiting 3 minutes when plugging in the keyboard the first time. If that does not work try switching USB ports.
The cable comes pre-installed with a 6.35mm jack. Unscrew it to reveal the smaller 3.5mm jack underneath. In addition there is a USB adaptor that the 3.5mm jacks of the headset and mic can be connected to.
