Hi @multiplexcuriosus Support for the L515 has been removed from the current latest 2.55.1 version of the RealSense SDK as L515 is a retired camera model. You will need to use 2.54.2 on your PC too. Sincere apologies for the inconvenience.

Thank you a lot for your answer!
Now I at least know what the problem was.
No need to apologize, it's not your fault I didn't check if the camera version is still supported.
Can you point me to a resource or briefly summarize the steps necessary to install the 2.54.2 version? As mentioned I did not succeed in doing that the first time I tried.

You can find the source code for a particular librealsense version from the SDK's Releases page and compile it with CMake using instructions at #9931 (comment)

Perfect, now it works. Thank you so much!

Before we close the issue, one more question.
The realsense-viewer works no, but the python API pyrealsense2 still seems to have problems.
The first few lines of the python script I am trying to run are:
import pyrealsense2 as rs
import numpy as np
import cv2
pipeline = rs.pipeline()
config = rs.config()
pipeline_wrapper = rs.pipeline_wrapper(pipeline)
pipeline_profile = config.resolve(pipeline_wrapper)
device = pipeline_profile.get_device()
device_product_line = str(device.get_info(rs.camera_info.product_line))
which results in the error:
Traceback (most recent call last): File "/home/jau/Documents/SP/shelf_localization/myScripts/rs_tuts.py", line 18, in <module> pipeline_profile = config.resolve(pipeline_wrapper) RuntimeError: No device connected
This is the same error I got when I was still using 2.55.1.
I already reinstalled pyrealsense2 to no avail.
Do you have a suggestion on how to get pyrealsense2 to work again?
from librealsense.
Never mind, I just had to downgrade the 'pyrealsense2' as well. All is working well. You may close the issue if you want.
from librealsense.
It's great to hear that you succeeded both with the SDK and pyrealsense2. As you suggested, I will close the issue. Thanks!
