Hi @AMR_all
Thank you for your post.
In the console log from your first screenshot, it printed a lot of warning about usb. If the situation is consistent, please try to reboot your device and run the demo again.
If the warning is gone but you still can’t get IMU data, you can try following tutorial.
Tutorial for Visual SLAM Using a RealSense Camera with Integrated IMU — isaac_ros_docs documentation.
I downgrade software camera d435I and I use IMU OK
Thank you very much
