Not working L500 Depth Sensor

[webant-ltd]

librealsense	2.43.0 RELEASE
OS	Linux
Name	Intel RealSense L515
Serial Number	f0245197
Firmware Version	01.04.01.02
Camera Locked	YES
Usb Type Descriptor	3.2
Product Line	L500
Asic Serial Number	0003b52af7f7
Firmware Update Id	0003b52af7f7

I'm using the USB cable that came with the L515.
Run realsense-viewer

After launching, I get an error

Invalid Value in rs2_open_multiple(sensor:0x7f6c78025d30,
profiles:0x7f6c782b2970, count:2):
hwmon command 0x2b( 4 80000000 0 0 ) failed (response -29= Value out of
range)

RGD Camera and Motion Module work stably.

I tried updating the firmware version to 1.5.5.0 (Signed_Image_UVC_1_5_5_0.bin). The error remains.

Hi @webant-ltd. I am having exactly the same problem - same errors are being shown in RealSense Viewer and when launching ROS Node. Funny thing is that it actually worked last week just normally. Can you confirm that as well or your sensor never worked as supposed? Thanks.

@taletovic I have the exact same thing, my camera worked last week. I have been having success with it.
I might have messed something up during installation of realsenselib and now it does not work anymore.
I also have a problem regarding USB 3.0 port. When i unplug the USB C on the camera and rotate in 180 degrees it gets recognised as USB 2.1 instead of 3.0.

[taletovic]

@theotromp97 I was using different presets (close range was interesting for me) as well as trying to save the settings in a .json file which could be later on loaded in the ROS driver. Maybe that could cause this problem, however I've no solution to it.

About the USB Port - it's a known phenomena (saw it in troubleshooting guide).

@RealSenseCustomerSupport any answer/comment on this? Please help.

I have this problem too, I followed the installation for the newest version 2.44 and in the end when I try to turn on the L500 Death Sensor I have error:
"Backend in rs2_open_multiple(sensor:0x7fa8ac01bca0, profiles:0x7fa8ac41c490, count:2):
xioctl(VIDIOC_S_FMT) failed Last Error: Input/output error".

Did anyone figure out a solution to this? The device was working fine last week but now I'm getting the exact same errors as @webant-ltd when trying to turn on the depth sensor. The motion module and rgb camera are working fine though. I've even tested it out on a different computer but the problem persists.

Hi All

If you're having issues with the streaming of the depth in the manner outlined above or even having issues with the USBC connection orientation changing behavior with regards to detected as USB2 or USB3, please open a ticket here: https://support.intelrealsense.com/hc/en-us/requests/new
