Got 3 camera works all good. Today add new successful, but trying to re-add and reduce some unused sensors. After remove the device and re-add with same config. It shows "Only a single instance of a device is allowed." But actuallt even when I add a camera already exist it will not stop doing that.

Anyone know how can I re-add the camera.
