Hello.
I have the Raspberry Pi 5 8 GB running Raspbian 64-bit (bookworm), which I'm trying to get to work with an Astra Pro HD Camera. Issue is I cannot get picamera2 or opencv to find the camera. After some research I've found USB camera support for the RPi 5 is quite limited as of now.
Changing hardware is sort of not an option, but does Ubuntu or 32-bit Raspbian work differently? I have to run ROS2, but this could be done in a Docker container. Being able to use the camera is essential.
