This problem is still present: Shotwell cannot access the camera although it is aware of its existence (it is correctly listed in the LH side menu, in my case a Kodak EZ200).
The recommended method of unmounting the device in a file manager seems to be bogus for many people: no device is mounted, so there's nothing to unmount. Something, somewhere, is grabbing the device when it is plugged in, and nothing seems to be able to detect *what* process is responsible. I'm attaching the syslog from when I plug it in. Perhaps someone with better usb-fu can make sense of it. ** Attachment added: "syslog of plugging in Kodak EZ200 under Mint 18" https://bugs.launchpad.net/ubuntu/+source/shotwell/+bug/1400470/+attachment/5146822/+files/ez200 -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to shotwell in Ubuntu.
