Update computer operating system. Restart computer with Center Cam UNPLUGGED. Attempt Center Cam connection again after restart. If using a USB hub, ensure that it is a powered USB hub. Center Cam requires the full amount of power provided by a USB 2.0 port. Many stand alone USB hubs will not allow for the full 5V 500mA of power that is provided from the computers USB port. If using a USB 3.1 port,  this can usually provide sufficient power to the other devices on the hub and Center Cam.
