Issue Description

I have a ROS 2 Humble docker image with realsense2 and librealsense2 installed from debian packages (sudo apt install). Everything related to ROS works. The Raspberry Pi detects the Realsense with lsusb.

When I try to use docker with the following command:

docker run -it --name humble_realsense --net=host --env="ROS_DOMAIN_ID=42" --privileged -v /etc/udev/*:/etc/udev/* \
    -v /dev/bus/usb:/dev/bus/usb \
    -v /dev/:/dev/  ros2humble_realsense:latest bash

The container does not find the camera:

However, the camera (or at least the IR camera) works fine with python3+OpenCV:

# python3

        [ 81,  81,  81],
        [ 81,  81,  81],
...

I think this issue is related to permissions or USB access in the Raspberry, because the same docker in my laptop works fine with the camera.

Has anyone had the same issues, or can give me any hint?

Thank you!

Hi @JLBicho My research of your question found a case regarding problems with using a RealSense camera with Docker on Pi where a suggested solution was to use sudo admin permissions (sudo docker run instead of just 'docker run').

sudo docker run -it --privileged -v /etc/udev/*:/etc/udev/* \
-v /dev/bus/usb:/dev/bus/usb \
-v /dev/:/dev/ \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e DISPLAY=$DISPLAY -h $HOSTNAME -v $HOME/.Xauthority:/home/.Xauthority realsense:latest bash

Hello @MartyG-RealSense, thank you for the quick reply!

I've tried the launching with 'sudo' and now a new error occurs:

$ sudo docker run -it --name humble_realsense_sudo --net=host --env="ROS_DOMAIN_ID=42" -v /etc/udev/*:/etc/udev/*     -v /dev/bus/usb:/dev/bus/usb     -v /dev/:/dev/  ros2humble_realsense:latest bash

There was a Pi and ROS2 case at IntelRealSense/realsense-ros#2545 (comment) that had this Mipi device capability could not be grabbed error. Installing librealsense from source code with a build script called libuvc_installation.sh resolved the problem in their particular case, as described at IntelRealSense/realsense-ros#2545 (comment)

I just happened to notice that contrary to @MartyG-RealSense code snippet, you seem to be missing the --privileged flag (and neither gave he container access rights to the Realsense with dedicated device_cgroup_rules). So the operation not permitted error might as well just be caused by that. So try simply adding --privileged before giving Marty's suggestions a go.

Hello,

I've tried both things, privileged with cgroups and compiling from source the libuvc and still the same error with MIPI.

I'll keep trying things and let you know. If you happen to come around some similar error, please let me know.

Thank you!

@JLBicho what does your ls -l /dev look like? Is your docker user in the video group?

If you're willing to run the development branch, this pull request allows you to pass into the container individual /dev/videoX devices without needing any extra privileges or volume/bind mounts.

docker run -it --name humble_realsense --net=host --env="ROS_DOMAIN_ID=42" --device=/dev/video0:/dev/video0:rw --device=/dev/video1:/dev/video1:rw ros2humble_realsense:latest bash

Obviously if you have more video devices just add more --device arguments in the same format.

@ciandonovan, thank for the suggestion.

However, I still get the following error:

[realsense2_camera_node-1]  11/01 17:23:21,655 ERROR [547247417568] (librealsense-exception.h:52) Mipi device capability could not be grabbed Last Error: No such file or directory

I don't think it has to do with the mounting of the device, rather some problem with the installation of librealsense.

Hi @JLBicho Do you have an update about this case that you can provide, please? Thanks!

Hello @MartyG-RealSense,

I haven't been able to try more things.

I'm trying to get a D400 to check if the problem is related only to the L515 or else. I'm also planning on changing the O.S. of the Rpi.

I'll let you know any advances.

Hi @MartyG-RealSense !

For now I'm a little stuck. I'm not able to make it work with either L515 or D435.

I'll try to reinstall the O.S. with Ubuntu instead of Raspbian.

Anyway, thank you for your support. I'll let you know if I finally get it working.

If you wish to close this issue, please do so.

I might have the same issue, but it worked in all old versions and still does. Only when I upgrade to 2.55.1.6486 it stops working.

I use a python:3.7-slim image on a NUC with Ubuntu installed.

Hi @sladomic When you upgraded to librealsense SDK 2.55.1, did you also update the camera's firmware driver to 5.16.0.1 which is the recommended firmware for 2.55.1. Using older firmware versions than the recommended can result in errors. And the previous SDK version 2.54.2 was mostly bug-fixes and so was not very different to 2.54.1, whilst 2.55.1 has a large number of feature and API changes.

Hi @MartyG-RealSense

Thanks for the fast reply. I haven‘t updated the firmware driver since I use a L515, which isn’t supported anymore officially.

However I can still use it when not upgrading to 2.55.1.

Edit: I just saw, that the release notes mention this Removed support for L515, SR300, so it makes sense, that it doesn't work anymore.

Thanks very much for the information about your camera model. Yes, L515 support is removed in 2.55.1 onwards.
