Troubleshooting • 4B + Arducam 5MP (ov5647) + Bookworm: no /dev/video0

Dear comrades,

Yes, I bought the knockoff V1 camera ... but still. I read a lot; I think I'm doing everything right. Is the camera broken, right out of the box?

terry@impudence:~ $ libcamera-hello --list-cameras

config.txt has:

In dmesg I'm getting:

This system is also running the Geekworm Gemini RAID board, in case that's relevant. It's a headless NAS server.

Grateful for clues!
