I’ve been using this Arducam USB camera module with my rpi (currently running octoprint for my 3D printer).
It was working fine for the last couple days until recently. I’m not sure what changed, but now anything trying to use the camera device seems to just hang.
I tried running the following command to test it by capturing a single frame:
fswebcam -d /dev/video0 -r 320x240 -v -S 20 --set brightness=100% test_image.jpg
But this gave the following error:
--- Opening /dev/video0...

I also noticed when plugging in the USB I see this in the kernel log (not sure if this has anything to do with the issue):

What could be causing this?
