i am using a D457 intel real sense camera with USB mode (i toggled the switch). i am trying to launch realsense2_camera_node

. its not showing any stream. I have checked my PC (Lenovo Legion 5) has USB3.1 Ports, Cable supports USB3.0 transfer.

Hi @RISHI-VEMPATI Is there a difference if you unplug the micro-sized end of the USB cable from the base of the D457, turn the connector around the opposite way and re-insert it into the camera, please? Cameras will sometimes perform better when the micro-sized connector is inserted into the camera in a particular orientation of the two insertion directions available.

If it does not make a difference, what happens if you launch with ros2 launch instead launching the node with ros2 run?
