realsense-ros: Lots of "Failed to read busnum/devnum" warnings polluting the terminal

I’m running on ros2 humble. I launch the camera with

ros2 launch realsense2_camera rs_launch.py

and I get this output

I get lots of this “Failed to read busnum/devnum” warnings. I’m showing the output of rs_launch.py to make diagnosis easier as it’s a provided launch. In the specific launch I’m writing I get event more of this Failed to read busnum/devnum" warnings and it makes hard to see other messages I’m interested in. The driver seems to be working normally though.

Note I’m running humble inside a docker with Ubuntu 22.04 LTS. In my host I have Ubuntu 20.04 with ROS Noetic and if I run

roslaunch realsense2_camera rs_camera.launch

with the same camera connected I don’t get any of the warnings above.

I’ve checked other issues with this warning message but none of their suggestions worked to eliminate this warning. Do you have any suggestions to eliminate this warning?
