    Hi,
    Nobody replied to my question, but finally I solved it myself. To be complete,
    I will post the solution here.
    I found a statement somewhere that USB removable disk technology in
    combination with SD cards contains code which is patented. When I switch the
    camera back to camera mode, the usb removable disk technology is not
    activated and the errors do not occur.
    The solution is to use gPhoto and the frontend gtkam which is able to get the
    photos off the camera.
