rs-enumerate-devices works only under root

edit

Glad to find this forum.

I have installed ROS Melodic and realsense2_camera on Raspberry Pi 4 wired with L515. Realsense2_camera was isolated installed.

By applying source ~/realsense2_camera_ws/devel_isolated/setup.bash rs-enumerate-devices works only under root, the camera is found and recognized.

With pi user camera is not found. "No device detected. Is it plugged in?"

By applying standard source /opt/ros/melodic/setup.bash command rs-enumerate-devices works for pi user. A few hours, but solution is not found, please, help.
