Realsense cannot find the camera
Hello, I followed realsense tutorial from the link. In the end when I ran the camera node it cannot find the camera. I did not install any other realsense software prior to this tutorial. My error log is below. Basically it says no camera is detected, even though my camera is attaced via USB3.0 port.
My camera is Creative BlasterX Senz3D Appreciate your help.

The
LIBUSB_ERROR_ACCESSerror message onlibusb_openmakes me think the driver found the device, but the user running ROS has no access to it. Try adding the user to theplugdevgroup, or modify/add udev rules to give the user access to this device (depending on your security requirements).Try adding the user to the plugdev group: How can I do it?
Adding a user to the plugdev group is the 3. option in my answer.
