Access to digital camera only as root

Hi Everybody,

Before anyone flames me for not digging around first for this often addressed problem, I just want to add that I have looked and found numerous threads ABOUT the problem, but I have not yet found any succinct solution to it. I have a Canon digital camera I am trying to use with digikam on Slackware. Can use it as root, but not as user. /var/log/messages reports this:

Apr 19 10:23:59 bobsbox kernel: usb 2-2: Product: Canon Digital Camera
Apr 19 10:23:59 bobsbox kernel: usb 2-2: Manufacturer: Canon Inc.
Apr 19 10:23:59 bobsbox kernel: usb 2-2: configuration #1 chosen from 1 choice
Apr 19 10:31:58 bobsbox su(pam_unix)[4172]: session opened for user root by (uid=1000)
I am familiar with chmod, but what permissions do I change and where? I have read threads where temporary solutions were found for one session, but is there a way to permently change permission to let a user access this camera through Digikam?

Any help very much appreciated.

I have this same problem? Do you know the answer?

Well, I DO have an answer!!!! RTFM!!!!! j/k

Seriously, you need to chmod the USB device file for the camera. You'll need to look in /proc/bus/usb for some directories containing device files for your attached USB devices. You will see directories with names like "001" and "002", etc. You will have to change the permissions on the right file to 666 and you should be able to access your camera correctly.

I can't guide you any better than that since I just realized I have USB problems of my own I need to deal with but if you start in /proc/bux/usb, you're going in the right direction.
