I currently have a Canon Hybride M3 that I partially defiltered.
Unfortunately it does not have a connector for the intervalometer. So I installed CHDK to have an integrated intervalometer.
I would like to be able to go further and so I saw that it was gphoto2 compatible.
Unfortunately it is not fully compatible. Via gphoto2 you cannot modify the parameters of the hybrid.
This is also valid for the M2, M10, M100, M6 Canon.
But you can still download the image and control a long exposure via the USB port.
