Well, now I can use gtkam as root to get photos out of my camera.
But still not as ordinary user.
By default the created on camera connection devices /dev/ugen0{,.1,.2,.3}
are owned by root:operator and have pervissions crw-r--r--. It
was easy to hack /etc/usbd.conf to change the permissions to crw-rw-rw-,
but it is not enough. Somewhere in the middle of communication with
the camera the device permissions of ugen0.* are reset back to 644 and
the program fails. Results from 'ls -Fail /dev/u*' before and after
gtkam run follow.
