[gphoto2] sane_init: error: Nikon CoolPix 800 is not a valid camera
type. Use "gphoto2 --list-cameras" for list.
bob sane-backends # gphoto2 --list-cameras
Number of supported cameras: 267
Supported cameras:
"Nikon CoolPix 800"
I've tried the camera= in /usr/local/etc/sane.d/gphoto2.conf with and without guotes.
I also have port=serial:/dev/tts/0 in /usr/local/etc/sane.d/gphoto2.conf
gphoto2 --list-ports
Devices found: 3
Path Description

serial:/dev/tts/0 Serial Port 0
