I am trying to get gphoto2 working to get some pictures from this old 
digital Canon EOS 350D camera but I do not know what happens.

netbsd-nuc# gphoto2 --list-files

If you need the full output I can send it to you.



I have tried in Linux and FreeBSD and gphoto2 --list-files works fine.


Thanks so much.
