I am working with Intel Realsense Lidar l515 camera. And after installing the Realsense Viewer on Win 10, it doesn't see my camera, with the next issue outputs: context.cpp:129 - Found 0 RealSense devices (0xfe requested & 0xff from device-mask in settings)

Hi @Manat09 Please first check the camera privacy settings in Windows to ensure that permission for applications to access the camera is set to On. Instructions for doing so can be found at https://github.com/IntelRealSense/librealsense/issues/3381#issuecomment-503424789
If the privacy settings are already set to On, next try unplugging the micro-sized end of the USB cable from the base of the L515 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).

Thank you for answering! But it did not help anyway.
If you check latest version of librealsense2, I think they remove the support for L515

Oh I see yeah, thank you very much!
@lipilian is correct that L515 support was removed from the current latest RealSense SDK version 2.55.1 as it is a retired camera model.
If you are using Windows and need to use L515 then you can download and install the previous SDK version 2.54.2 which still had L515 support.

Hello, can we install from this website also to Linux?
Hi @Manat09 Building librealsense from its GitHub page would build the latest 2.55.1 version.
You may be able to install from packages instead of source code if you use the command apt-cache showpkg librealsense2 to show a list of librealsense package versions and install the 2.54.2 version of the packages, as described at https://github.com/IntelRealSense/librealsense/issues/10526#issuecomment-1129748073
The full instructions for a package installation can be found at the link below.
https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md
In the section of the instructions where it asks you to install the following two packages:
sudo apt-get install librealsense2-dkms
sudo apt-get install librealsense2-utils
use the 2.54.2 names of these packages obtained with 'apt-cache showpkg librealsense2'
Hi @Manat09 Do you require further assistance with this case, please? Thanks!

Hi, thank you so much, now I didn't started the project with your methods. Later I will try and give you feedback.
You are very welcome. I look forward to your feedback later. Good luck!

Hi, after using this command: sudo apt-get install librealsense2-utils=2.54.2-0~realsense0.2181 librealsense2-dkms=2.54.2-0~realsense0.2181
I got next output:
E: Version '2.54.2-0~realsense0.2181' for 'librealsense2-utils' was not found
E: Unable to locate package librealsense2-dkms
Do you know how to solve it? Thank you!
If the packages cannot be found then there is not a way to solve it, unfortunately.
The only option left available would be to first remove all RealSense packages from your computer with the command below.
dpkg -l | grep "realsense" | cut -d " " -f 3 | xargs sudo dpkg --purge
Then visit the SDK 'Releases' page for 2.54.2 at the link below and use the 'Assets' list at the bottom of the page to download the 'Source code (zip)' file to your computer.
https://github.com/IntelRealSense/librealsense/releases/tag/v2.54.2
Finally, extract the librealsense source code folder from the zip and use the folder to build the source code with CMake using the instructions at https://github.com/IntelRealSense/librealsense/issues/9931#issuecomment-964289692

Thank you very much!!! Everything is working now. With this version I can use my camera l515.
