Right device name on device manager, but cannot be used?

Although the device appears to be installed correctly and the software can also select the device, it prompts that the selected device cannot be used.
At this time, it is because the software thinks that the video capture device is a camera device and is not turned on in the privacy settings of the computer.

Click the Windows icon in the lower left corner of the computer-settings icon-privacy-camera-open to allow applications to access your camera.

Complete the above settings and open the software settings again to successfully capture the video.
