[CentOS] Centos 7 - Canon Powershot A410

I have an old Canon Powershot A410 camera that used to just work with
Centos 6.  All I had to do was install Shotwell and forever after I
could just plug that camera in and Shotwell would automatically load and
all was well.

I'm now trying to get that camera to work on Centos 7, but am having no
success.

Jul 20 16:01:44 jeff mtp-probe: bus: 2, device: 4 was not an MTP device

That last line isn't surprising because this camera apparently used PTP
and not MTP.

So does anyone know how to enable PTP mode?  As far as I can tell the
(installed) libgphoto2-2.5.15-1.el7.x86_64 is supposed to support PTP
mode cameras but somehow it's not being activated or something?
