For those who are experiencing this issue:

• It seems to be a problem on the board we have. I contacted ArduCAM by e-mail and the boards I got directly from them worked without any problem.

Just for documentation, you can make the "not-working board" work, at least for development, following the steps described by @lrnzo

Our team tried to manually create the /dev/video0, in order to make the boards work without this trick, but we have not success so far. The interface is created, it passes on the ArduCAM's script test but it does not work to capture images.

Maybe you are already a super user in this machine, therefore using sudo would cause this problem. Can you try to run the following commands and paste here the output?

ls -la
chmod +x init_camera.sh
./init_camera.sh
