"could not claim device" usually means permission problem.

Attach lshal output with camera attached please.

I just tested running digikam with kdesu and it worked fine, which means you're right, Meissner. But I didn't figure out what happens, since I didn't touch the device ownership and my flash card reader at same usb port works well.

That's weird, I'll might take a look again later. Thank you for the useful tip.

Flash card reader are mounted by the kernel. Mount use root privilege.
Unlike the camera.

If that happened recently, I know the reason. hal recently deprecated the "info.bus" property, thus libgphoto2 (and libsane, too, see bug 205496) need to generate FDIs with "info.subsystem", not "info.bus".

This bug was fixed in the package libgphoto2 - 2.4.0-8ubuntu6

---------------
libgphoto2 (2.4.0-8ubuntu6) hardy; urgency=low

  * Add debian/patches/72_deprecated_hal_key.dpatch: Replace the deprecated
    hal property "info.bus" with "info.subsystem" in the hal FDI generation
    tool. This fixes cameras to work with current hal without using deprecated
    keys. (LP: #205417)

Gentlemen,

After an "sudo apt-get update; sudo apt-get upgrade" everything is working fine. I just tested it.
