So I've had an ACER chrome book for two years. I record a podcast and until now I've used a headset with a mic that plugs in to the USB drive, and the webcam built in to the chrome book. I just bought a USB recording mic, but when I plug it in, the camera becomes unavailable. The second I unplug the mic, the camera comes back. Any ideas how to make this work, or is this a lost cause?
