I've been using gphoto2 and nautilus to access various Canon cameras for years, using each step of Ubuntu over that time.
Its working well for me in 12.04. But my understanding, is that it does not present as a regular flash drive. There is a special driver that makes browsing possible in nautilus, and gphoto2 has this built-in. I've always heard the limitation is that its read-only. I'm not aware that you could ever copy files to the flash card in your camera from any tool in Ubuntu. Although I have no need to do that, so I have not tried. In my install, a simple "gphoto2 -P" does it all for dumping photos from camera to disk. Oh there is one other thing, nautilus will claim the device when you plugin your Canon. Since I prefer gphoto2 I just click the eject icon in nautilus to release the device. Then gphoto2 works fine. I know this will not help everyone, just offering some input.
