Troubleshooting Connectivity and Streaming Issues on Intel® RealSense™ Cameras D400 on Linux*

What am I seeing?

• Intel® RealSense™ software tools don't recognize the camera at all.
• Can't see stream—Depth, IR, RGB—or streams aren't available in Intel RealSense Viewer or other application.

Why am I seeing it?

• Camera not connected to a USB 3 port
• Faulty installation of librealsense
• Unsupported Linux* kernel

Ways to fix it

• Connect the camera to a USB 3 port.
• Upgrade the camera's firmware.
• USB 2.0 is supported, but fewer streams are available. See the datasheet for Intel RealSense Depth Cameras D400 for more information on supported streams when connecting the camera to a USB 2 port.
• Patch the kernel as needed by following these instructions.
• See this page for more Troubleshooting information.

How do I collect logs?

1. Plug in the Intel RealSense Camera D4xx into a USB port and enter:
   1. lsusb -v | tee lsusb_4xx.log
   2. dmesg | tee dmesg_4xx.log
2. Contact Intel Customer Support and attach log files to case.
