[ROS1 WSL Ubuntu 20.04] Failed to open usb interface

[Elektron97]

Required Info
Camera Model	D435i
Firmware Version	5.16.0.1
Operating System & Version	Ubuntu 20.04 (WSL)
Platform	Laptop (WSL)
ROS Distro	Noetic

In WSL2 I tried to launch:

roslaunch realsense2_camera rs_camera.launch

and I obtained this error:

[ INFO] [1730887040.305924387]:

For the installation, I typed:

sudo apt-get install ros-noetic-realsense2-camera

I saw online that a file 99-realsense-libusb.rules is required, so I pasted it from here as suggested in this issue for Ubuntu 18.04. Unfortunately, it didn't work. Are there some different solutions for Ubuntu 20.04?

Hi @Elektron97 I would not recommend using WSL2 with RealSense if possible. It can be problematic to get it to work with librealsense, and getting it working with the RealSense ROS wrapper can be even more of a challenge.

In the past Microsoft have recommended using Windows 11 with WSL2 rather than Windows 10, as mentioned at #2481 (comment) - are you using Windows 10 or 11, please?

HI @MartyG-RealSense , thank you for the answer. I'm currently using Windows 11.

I note that you are using ROS1 Noetic, which suggests that you have version 2.50.0 of the librealsense SDK installed and the 2.3.2 version of the RealSense ROS1 wrapper installed as you used the installation command sudo apt-get install ros-noetic-realsense2-camera

If you are using librealsense 2.50.0, the recommended camera firmware driver version to use is 5.13.0.50 instead of 5.16.0.1.
