1 day ago Hi @jin-yiwei Support for L515 ended in librealsense version 2.54.1 because it is a retired camera model. If you are using the RealSense ROS wrapper then I recommend installing the 2.50.0 or 2.51.1 version of librealsense, and using the 4.51.1 ROS2 wrapper in order for your L515 to be detected.

10 hours ago Thanks for ur reply. But it seems the 2.54.1 version doesn't support ubuntu 22.04 because of the kernel version problem. The focal patches only support up to 5.11 kernel. Is there a better solution that I can launch l515 on 22.04?

2 hours ago You could build 2.51.1 from source code using the RSUSB Backend procedure described at https://github.com/IntelRealSense/librealsense/issues/9931#issuecomment-964289692
The 2.51.1 librealsense version's source code can be downloaded from the 'Assets' file list at the bottom of the page linked to below.
https://github.com/IntelRealSense/librealsense/releases/tag/v2.51.1
When librealsense is installed with the RSUSB Backend method, the build is not dependent on a particular Linux version or kernel version and does not require a kernel patch script to be run.
Once librealsense 2.51.1 has been successfully installed then you can build the 4.51.1 ROS2 wrapper from source code. There is a custom 'forked' version of 4.51.1 created by a RealSense ROS user at the link below that you could build.
