[solved] Digital Camera not recognized in device-manager

Question

My digital camera "Canon Powershot SX120 is" is not recognized by the devicemanager. I have read Digital Cameras.
$ groups
wheel storage users printadmin
The "camera"-Group isn't needed anymore and this group doesn't exist on my system.
The Powershot SX 120 has a  MTP/PTP connection mode (as the manual says). But:
# mtp-detect
Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6
Listing raw device(s)
No raw devices found.
gphoto succeed:
$ gphoto2 --auto-detect
Modell Port
Canon PowerShot SX120 IS usb:002,019
A gphoto --summary could be found here
There is no udev-rule for this camera. If i create one while copying a rule from a similar camera from /etc/udev/rules.d/69-libmtp.rules, and store it into /etc/udev/rules.d/69-canon.rules, the device-manager shows up. My udev-rule:
# Canon PowerShot SX120AX (PTP/MTP mode)
ATTR{idVendor}=="04a9", ATTR{idProduct}=="31e0", SYMLINK+="libmtp-%k", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"
The device-manager shows me only the option to open with a file-manager. Doing so will result in an error:
The file or folder udi=/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:02.1/usb2/2-8/ do not exist.
With my udev-rule:
solid-hardware listen
Object::connect: No such signal org::freedesktop::UPower::DeviceAdded(QDBusObjectPath)
Object::connect: No such signal org::freedesktop::UPower::DeviceRemoved(QDBusObjectPath)
Listening to add/remove events:
Device Added:
udi = '/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:02.1/usb2/2-8'
Without the active udev-rule, "solid-hardware listen" produces nothing, but
udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent
KERNEL[5077.662572] add /devices/pci0000:00/0000:00:02.1/usb2/2-8 (usb)
KERNEL[5077.662655] add /devices/pci0000:00/0000:00:02.1/usb2/2-8/2-8:1.0 (usb)
UDEV [5077.681178] add /devices/pci0000:00/0000:00:02.1/usb2/2-8 (usb)
UDEV [5077.693035] add /devices/pci0000:00/0000:00:02.1/usb2/2-8/2-8:1.0 (usb)
Don't know what to do ... is a udev-rule necessary to bring up the message from device-manger? Or is the Camera not recognized as a mtp-device (the Camera has no such settings)? How could i figure it out?
With Digikam i could import Fotos, but i would do so with gwenview. I've tried to check it out with gwenview_importer:
$ gwenview_importer --udi '/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:02.1/usb2/2-8'
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
gwenview_importer: Missing required source folder argument.
  (don't care about the different udi, i took this example from a former try) but i don't know, how to find out where the "source folder" is ...

I have solved this by making an extra udev-rule for my camera. See my adventure on forum.kde.org for details
