I have a pi 3b+ running Raspbian stretch. c920 had been working out of box with the official v4l2 driver.
I install UV4L to play with the webrtc features. But found some problems. So I did an apt remove on all the uv4l packages.
But afterwards, C920 cannot be register.
lsusb shows the c920 is still recognized on the USB bus.
But /dev/video0 is missing.
I tried uninstall and re-install v4l-utils. But didn't help.
sudo modprobe bcm2835-v4l2
didn't do anything, nor throwing any error either.
Anyone can help me debug the problem? Thank you!
