Input following command

xxxxxxxxxx
lsusb

The system will list information about all USB devices connected to the development board.

If the development board does not recognize the corresponding device after connecting the camera, we can use a different USB interface or connect the camera to the computer for testing!

If the camera information still cannot appear after changing the device, it is usually caused by a hardware problem.

Input following command

x
ls /dev/video*

The system will list all device information related to the video device.

If only one camera is connected, generally we use the /dev/video0 device.

video0 is image/video collection, video1 is metadata collection.
