Maybe a fresh set of eyes can provide insight, from your post;

A bit later;

Do you now see the difference between what is reported as your camera and
what gphoto2 is looking for???

According to; http://www.teaser.fr/~hfiguiere/linux/digicam.html

Panasonic DMC-LC20 0x04da/0x2372
Panasonic DMC-LC33 0x04da/0x2372 (USB Mass Storage)
        
        
So try something like;

gphoto2 --camera="Panasonic DMC-LC20" --port=usb --list-files

Or ask for help with support for your camera in the the Usenet News
discussion group rec.photo.digital and checkout the links from;
http://www.gphoto.org/links/
