This is now broken with two cameras that used to work fine (a Canon SD1000 and a Nikon Coolpix). Details... udev appears to see the hardware just fine, but libgphoto (plus nautilus, gthumb, etc) doesn't see anything to import from (although mtp-probe seems to work on just about anything). Absolutely nothing happens now in the Gnome desktop when I plug a camera in, and it seems to be completely invisible to the import tools. Moving the libmtp rules so they run after libgphoto doesn't change anything, nor does removing libmtp completely. Other than one or two previous glitches between libmtp and libgphoto devices, cameras have generally worked fine on Gentoo, and still work on ubuntu (which uses much older libgphoto packages). # tail /var/log/messages Mar 19 14:11:01 rama kernel: usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Mar 19 14:11:01 rama kernel: usb 2-2: Product: Canon Digital Camera Mar 19 14:11:01 rama kernel: usb 2-2: Manufacturer: Canon Inc.

Maybe you don't have needed camera set in "CAMERAS" variable. Please take a look on libgphoto2 news item ("eselect news list")
No, I have the right camera options enabled. I removed the last vestiges of hal and rebuilt some things, but I think what fixed it was replacing the front-panel widget in the case with one that I knew was a solid unit. Now both cameras work just fine (as expected) so I guess you can't always trust the case hardware to work like it should. I'm short one 3.5" removable slot, but I have 4 rock-solid USB connectors so it was worth it. Closing...
