librealsense: WARNING : (d400-factory.cpp:1195) DS5 group_devices is empty.

I get this output when trying to execute

ros2 run realsense2_camera realsense2_camera_node

on my DEBIX Model A (2GB RAM) with Ubuntu 22.04 (Debix Image) (Kernel 5.15) and ROS2 Humble installed:

The sudo rs-enumerate-devices command works fine (only doing it with sudo):

I’ve just seen that the camera’s firmware version is lower than recommended. How do I update it?

Hi @jesusramondovale Yes, firmware 5.15.0.2 should be used with SDK 2.54.1. The firmware can be updated in the RealSense Viewer tool by going to the More option near the top of the Viewer’s options side-panel and selecting **Update Firmware from its drop-down menu, then navigate a pop-up file selector from a firmware .bin file downloaded from the link below.

If you do not have access to the RealSense Viewer then you can also update using the text-based tool rs-fw-update and a firmware .bin file from the link above.
