Hi Marco I did some investigations into the libphoto2 udev rules issue, maybe this helps you finding a solution. (I am using udev 0.100-2.2, libgphoto2-2 2.2.1-10, kernel 2.6.18-2-686 2.6.18-4)
The camera I use here is an older one (HP Photosmart R507) which used
to work with sarge and hotplug. Which means a lot of cameras where no
explicit vendorid .. is provided, will not be supported only because
the devices does not get the right groups. :(

If I comment out the above lines, the following devices get the
plugdev group
/dev/usbdev2.7_ep81
/dev/usbdev2.7_ep01
/dev/usbdev2.7_ep82
but not /dev/bus/usb/002/007 which is used to get access to the
photos.

With the rules provided in libgphoto2-2 no device gets the plugdev
group.
