Hello again,

in #ubuntu-devel, they suggested this bug might in fact be related to
gphoto2 and/or libgphoto2. It should use udev instead of libusb for
monitoring cameras.

Please also don't forget Sebastians link to libmtp's source code
tracker. Both mice (Ruperts and mine) have "HID" as interface class.
Now, libgphoto2 doesn't have any checks on this [I found it in:
libgphoto2-*/gphoto2-abilities-list.c in libgphoto2, function
gp_abilities_list_detect_usb()].

So as a workaround, I'd rather give this bug in the hands of the
libgphoto2-devs to add the same workaround which is being used in libmtp
Sebastian showed us. Also, ebroder in #ubuntu-devel suggested that
gphoto2 rather should use udev to monitor for new devices. But this
would have a lot more impact on the whole distribution. Therefore this
would be a goal to a new major version, perhaps.

Αs a workaround:
* attach a camera while using shotwell (verified with »works-for-me«)
* add HID-detection to [lib]gphoto2
* perhaps, instead of workaround #1, create a virtual dummy camera, which is then being hidden by shotwell. Ugly, but *might* work. 

Since I am now convinced, gphoto2 should update their packages, I'll add
them here as well.

Hope this helps.
Best Regards,
Ben
