I confirm this with FC-6 and Olympus 3030 hardware today, also gphoto2 result.
My FC-6 is a fresh install with all updates per two days ago.
  See comment #33 / all revs are later than those listed.
  Add digiKam is R0.9.0(Using KDE 3.5.5-...fc6), gphoto2 is R2.3.1
Analysis:
With digiKam -- The camera connect request 
  First opens a camera window - then opens a fatal error window.
    "Failed to connect to the camera. ..."
With gphoto2 --list ports
  Two ports found prior to camera - ptpip:, and usb:
  Two more found after camera "ON" - usb:001,004, usb:002,003
With gphoto --auto-detect
  Olympus C-2100UZ found (wrong!?  Olympus-3030Z also exists in .fdi)
     May not matter? from inspection of .fdi, 2100UZ and 3030Z seem similar...
     Forcing use of C-3030Z yields same result.
  Two ports listed - usb:, usb:001,005
     I suspect first (without x,y) entry may be incorrect...?
     NOTE! from /proc/bus/usb directory listing
        usb:001,005 does exist with OK UID & permissions
        usb:002,003 does exist with only root perms
        usb:001,004 does not exist (see --list ports above)
With gphoto2 -a
  On the surface the output seems normal and correct
With gphoto2 ... -l
  Fatal error: "Could not release interface 0 (Invalid argument)."
  I have debug trace available --  if useful eamil me for attachment...
  Error began with this:
    "...gphoto2-port(0): Could not query kernel driver of device"
NOTE:
My FC-5 had lesser problem - only root could use USB camera interface.  Today the issue is a more total failure, probably with HAL and setting USB drivers.  I find nothing to adjust nor a workaround.  Advise if I can can further test.
