[SOLVED] 1224:2a25 webcam stopped working after update

I have a 1224:2a25 webcam that has worked for at least a year. Recently, some upgrades were installed, and now cheese and zoom get no video. This is ubuntu 20.04 with 5.13.0-51-generic kernel. I noticed that uvcvideo shows used by =0 in lsmod, I don't know if that indicates anything.
The camera is ID'd as USB PHY 2.0 Mono.
I did see an article about device file protections, but that is not the problem here.

Thanks in advance for any hints.

Well, it appears it had nothing to do with software updates. I tried it on another computer, and I get the same thing, totally black image, so it appears the cheap webcam has just gone bad. sorry for the noise.
