Camera not working, screen goes black, two red LEDs light up

My ST32N6 Discovery apparently works very well, however, when I enter the AI ​​demo, the camera screen goes black, and two red LEDs light up on the RGB LEDs next to the connector.

If I remove the camera, the DEMO alerts that there is no camera.

There is no LED on the camera module to indicate its status.

Are there any tests I can do to check if the camera is damaged?

Unfortunately, I can no longer return it, as it has been more than 60 days since I received it and only today was I able to take the time to do a more in-depth study of the camera.

I identified the problem; the USB ports on the two computers I tested are unable to adequately power the board when the AI ​​example is activated. I tested it on a third computer (laptop), and it worked there.
