You misunderstand my question.
I understand all that. However, when I plug my camera in, KDE pops up a
dialog box saying new hardware found what you you like to do. One
choice is to use digikam.
In the past when this has happened (with cameras which emulate usb mass
storage and therefore do not need special drivers) digikam has put up a
dialog box with thumbnails of all pictures in the camera, and an offer
to select and download these into an album.
With my new camera (which has this same support) it fails whilst trying
what show pictures it has in the camera. The udev-hal-dbus chain is
not working correctly because the mount point /media/sdg1 does not seem
to have been created.
Furthermore - when I try and use udev to make the camera device
have /dev/camera as its device, kde's dialog box pops up the first time
after a reboot when I plug the device in, but not again when I unplug
it and plug it in again. If I do not have a udev rule to alter things
it does pop up a dialog box every time.
In order to debug and track down what is not working, I am asking how
the udev-hal-dbus chain interacts with kde and digikam, and where to
look for configuration parameters so I can figure out what is not
working due to configuration problems and what might be a bug in kde
(or hal ...).
