If the camera supports PTP, use a gphoto2 (CLI program)
or a GUI tool that uses it (e. g. Gtkam for Gnome,
Digikam for KDE).

You'll find them in the ports collection.

Also check the menu of the camera if it can be switched
between PTP mode and DA mode. I have a Canon S3 IS myself
and it can do both modes, but I prefer extracting the
memory card and using it with the internal reader of the
computer instead of messing with the USB cable. :-)

In the past, I had a camera that worked very well with
gphoto2. It did identify to the system as ugen (USB
generic), no further messages appeared.

See "man gphoto2" on how to scan for devices and how to
copy (and maybe delete) pictures from the camera. You
can also automate this process (using devd) or use a
GUI solution for it. I've been using Gtkam in the past
for the task of selectively dealing with pictures.
