Hi @bsseo89 A control_transfer returned warning can indicate that there is a communiction problem between the camera and the computer, typically with the USB system (the USB port or the USB cable).

Which model of RealSense camera do you have, please? And are you using the official USB cable supplied with the camera or a cable of your own choice?
