I’m not sure whether the Canon_Capt driver is actually the correct one.
It is not in the list on the Arch wiki @maycne.sonahoz linked to - but the name is explicitly mentioned in the driver @ydar mentioned.
Should it be the correct one then I have at least some help to offer, since the installation instructions in the Arch wiki are not exactly … intuitive and easy to follow.
I have another model which uses this driver
and I have written here on more than one occasion on how to install it.
