once upgrading to FC5 I lost my ability as a user to use my digital camera.
Everything works still fine if I use it as root. As a used, from gphoto2 --debug I got
0.339543 gphoto2-port-usb(1): Looking for USB device (vendor 0x4a9, product 0x30ff)... found.

and the relevant part from root account is:

I'm confident that the problem with permission. In FC4 the hotplug was used which setup such permission.
What's the equivalent in FC5. I read about udev and even was able to write two rules,
one for my usb stick and another for my camera. The problem is that my camera is not
mounted as USB drive, I need to use software in order to download my pictures.
From past experience I have suspisious that it may be related to wrong SELinux settings, I may be wrong though.
I would appreciate any feedback on this issue.
Valentin.
