Comment 9 for bug 145239

@Johan: yes, libgphoto2-2 version 2.4.0-2ubuntu2 should have fixed it.
When it does not for you, you have another problem.

Install gphoto2 and run

  gphoto2 --auto-detect

if gphoto2 finds your camera and digikam does not then you _still_ have the
bug, but I doubt it. Did your camera work before in LInux?

  gphoto2 --list-cameras

does not list your camera so I assume it's not supported. Check www.gphoto.org
if you model if there's a known workaround.
