I have trouble getting access to my Canon camera.

I register it (digikam, KDE control centre) with USB PTP.
The USB device is perfectly recognised (see below).

However, an attempt to use the PTP protocol in KDE leads to an error
pretending the camera is not reached.

Also I don't know under which device the camera should be created : I
expected /dev/sda1 (or at least a sd* device), but nothing is created.
(while it is perfectly created with my USB key)


Am I missing a module or something ?

Thanks for any clue.

I dont't have any trouble with this camera. I just emerged the gtkam and autodetect the fotocamera in Camera|Add camera window. U can try to do that with root privilegies.

Hmm, as a matter of fact, it is a matter of root privileges.
I can perfectly run digikam (ot else, using gphoto2) as root, and everything goes fine.

However, as user, I can 'autodetect' the camera alright (-> USB PTP), but I cannot get the images.
This is a typical permission issue.

The problem is : I cannot find the incriminated device !!!

Not any of /dev/sg* or /dev/sd*

when I plug the camera, 'dmesg' gives me :

Code:
usb 3-2: new full speed USB device using uhci_hcd and address 14



any idea ?
