I am trying to get the integrated webcam on an Acer Aspire laptop to work but there is no image coming out of Cheese. When Cheese runs, the LED next to the webcam comes on but there is no image. Cheese GUI is shown below. Nothing works. What can I do?

I know everyone is affected by COVID19 during this period and undergoing some form of lockdown/inconvenience. Webcam is really necessary at this stage. I am trying to help someone get their webcam to work. Thanks.

I found answers on this similar question for 14.04. But don't seem to be able to use those solutions. I also noticed this Acer Aspire notebook does not have a shortcut/Function key to manually switch on/off the webcam like some of the laptops mentioned in the link.

Based on the outputs from the terminal, I know Bus 001 Device 005: ID 0bda:57cc Realtek Semiconductor Corp. HD WebCam is the webcam that this system is using. However, uvcvideo can't seem to initialize it. What can I do here?

I found this website on UVC supported devices. It seems that this class only supports 2 Realtek webcams. 0bda:57cc does not appear to be supported.

Any thing else I can do in this situation to get this webcam to work?
