[MartyG-RealSense]

Hi @danielhertz A xioctl(VIDIOC_G_CTRL) error usually indicates that there is a conflict between the librealsense SDK and the Linux kernel, Which kernel version are you using, please?

[danielhertz]

@MartyG-RealSense hello, ty so much for ur help, im using karnel version 6.5.0-21-generic

[MartyG-RealSense]

Kernel 6.5 support has been added to the development branch of librealsense - please see https://github.com/IntelRealSense/librealsense/commit/9f4f0b4140b335966656df194004afba1b423c75

The development branch becomes the next 'master' latest release of the SDK when published. The next SDK master release is planned for the Q1 2024 window (January to March).

https://github.com/IntelRealSense/librealsense/tree/development

In the meantime, in situations where librealsense is conflicting with the kernel, the SDK can bypass the kernel if the SDK is built from source code with CMake with the build flag -DFORCE_RSUSB_BACKEND=TRUE included in the CMake build instruction. This bypass is useful when a recent kernel is not yet supported by librealsense or when the computer being used is an 'exotic' configuration such as an industrial computing board.

A faster way to build the SDK with the kernel bypass is to use the libuvc backend installation method.

https://github.com/IntelRealSense/librealsense/blob/master/doc/libuvc_installation.md

[danielhertz]

@MartyG-RealSense ty so much for the comment and support. ok, i downgraded my ubuntu version from 22.04 to 20.04 and my kernel now is 5.15 and its still the same error, i can see the poinclouds, rgb and the rgb(also in cheese), i tried it in the windows partition and its not having the same one. im using laptop msi i7-11. im banging my head for some time and wish i could know whats the problem

[MartyG-RealSense]

The Windows version of librealsense runs on a different backend to the Linux version. The Windows SDK's backend is Microsoft Media Foundation and the default Linux backend of the SDK is V4L2.

Which method did you use to install librealsense on Linux, please?

[danielhertz]

from the https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md with the master

[MartyG-RealSense]

The current master at the time of writing this (2.54.2) will not have kernel 6.5 support, as that is on the current development branch (which becomes the next master release). The installation.md instructions build the SDK from source code but with reliance on a kernel (the kernel is not bypassed).

So you could try following the installation.md instructions again, but skip the part involving patching the kernel. Instead, in the CMake build instruction add the flag -DFORCE_RSUSB_BACKEND=TRUE in order to enable the SDK to bypass the Linux kernel and therefore hopefully avoid the VIDIOC_G_CTRL error.

[danielhertz]

well i dont have the error but other accured by this set r those cruicial for the ros wrapper ?

@MartyG-RealSense sorry for dudnt tagged u for the comment above

[MartyG-RealSense]

It's no problem. You do not need to tag me if I have already commented on an issue as GitHub will automatically send new messages to me. :)

The messages look quite serious. The Failed to set power state errors indicate that the camera cannot be accessed.

Are you using the ROS1 2.3.2 wrapper version or the ROS2 4.54.1 wrapper, please? If the ROS1 2.3.2 wrapper is being used then librealsense 2.50.0 or 2.51.1 and firmware driver 5.13.0.50 must be used.

Which ROS launch instruction are you using?

[danielhertz]

well, i didnt get yet into the realsense ros wrapper coz i know its bassed on the sdk (that was my mistake before with the xioctl error or am i wrong? ). for now im so despparate to make the sdk works propparly even i can c in the viewer the rgb and the pointclouds. so we solved one issue and now theres another. maybe its an hardware problem of msi laptops, what u think kind sir ? :) btw, sorry about my lame english

[MartyG-RealSense]

Your English is good, don't worry.

Are you accessing the camera with more than one program at the same time? If you had depth and RGB enabled in the RealSense Viewer and then ran another RealSense program, the second program would not be able to use the depth and RGB streams. This is because the first program that is run locks access to the streams so that a second program cannot use the streams until the first program stops using them. For example:

Viewer uses depth and RGB first. A program script run secondly afterwards cannot then use depth and RGB. Or

A program script uses depth and RGB first. If the Viewer is run secondly afterwards then it cannot use depth and RGB.

[danielhertz]

this is while the viewer works, it seems that there r no conflicts that running while the viewer is in the bkround

[MartyG-RealSense]

If realsense-viewer works correctly, what are you running when the errors occur, please?

[danielhertz]

nothing, just the browser and the terminal on an new ubuntu

[MartyG-RealSense]

It is difficult to see where the problem is occurring that is causing these errors. You built the SDK from source code with -DFORCE_RSUSB_BACKEND=TRUE. This build method bypasses the kernel so there should not be kernel conflicts, and RSUSB = true does not care which Linux version is being used and so using Ubuntu 22.04 or 20.04 should not be a problem.

If realsense-viewer is working correctly and the errors are in the terminal, is it possible for you to just ignore the terminal errors?

[danielhertz]

ok i moved forward to the ros wrapper(i upgraded again to ubuntu desktop 22.04, and DFORCE_RSUSB_BACKEND=TRUE to bypass the kernel) and its stuck in an warning when i simple launch:

If you are able to see streams even when warnings and errors are displayed, it possible for you to just ignore the terminal errors?

[MartyG-RealSense]

Hi @danielhertz Do you require further assistance with this case, please? Thanks!

[danielhertz]

well its still the same problem, the wrapper wont let me launch the camera and its not working with rviz2. i installed again the ubuntu with minimal that maybe the conflict with other programs will be solved and ill install again the sdk, lets c if it will work properlly

[danielhertz]

the same :(

Please try unplugging the micro-sized end of the USB cable from the camera, reversing the connector's orientation and plugging it back into the camera (USB-C cables are two-way insertion at the micro-sized end). Does doing so make any difference?

If that does not work, do you have another USB port to try the camera in?

Have you tried adding initial_reset:=true to your ros2 launch instruction to reset the camera at launch?

If that does not work, can you try launching with ros2 run instead of the launch file if you have not done so already, please?

ros2 run realsense2_camera realsense2_camera_node

[danielhertz]

@MartyG-RealSense ok, i dived in and found out that in msi laptops boot, there is an option to get more options by pressing shift+ctrl+alt+f2 and the were opened lots of more options to change, the "usb support"(changed to initial) and "fast boot"(changed to disabled). the errors dissapeared like there never were but only when i open the stereo module an warning apears: "11:04:46 [Warn] /home/daniel/librealsense/src/libusb/messenger-libusb.cpp:42 - control_transfer returned error, index: 768, error: Success, number: 0 " hope that warning isnt crusial and now ill go on for installing the wrapper again. ill let u know if it worked. btw, ty so so much

[MartyG-RealSense]

You are very welcome, @danielhertz - thanks very much for the update with the detailed information about what worked for you!

It is possible for the ROS wrapper to work normally even if the control_transfer returned warning is generated in the terminal. I look forward to your next report. Good luck!

[danielhertz]

well, im lucky, it didnt worked

[MartyG-RealSense]

Have you checked whether the streams are being displayed in RViz, please? Sometimes the streams will publish correctly in RViz even if control_transfer returned warnings are continuously generating in the log.

[danielhertz]

[MartyG-RealSense]

Are there still red errors in RViz if you change Fixed Frame from map to camera_link

[MartyG-RealSense]

Hi @danielhertz Do you require further assistance with this case, please? Thanks!
