Usb 3.0 is a requirement for realsense. Therefore, the sensor has a usb 3.0 connector. So the problem is either in the USB port of the PC or in the usb cable
- Make sure that you connect the sensor exactly to the USB 3.0 port
- Try another cable
Try it until USB “3.0” (3.1, 3.2) appears in Realsense Viewer
