PTP camera, setting rights does not work

[Anton Pussep <anton-ml@pussep.de>]

Hi everybody,

I experience difficulties to access my PTP camera as non-root. The 
camera is a Canon A580, that supports PTP via USB very well. I can 
access the camera as root, but not as a local user.

Using the gphoto manual 
(http://www.gphoto.org/doc/manual/permissions-usb.html) I tried to make 
hotplug and HAL set permissions, but it did not work. For hotplug I 
created a usbcam.usermap and a usbcam script, but the script does not 
get executed. After that I tried HAL, but it seems like there is no 
policy file for gphoto.

I don't know how to proceed in this problem, may be someone else has an 
idea? Who should be responsible for setting rights in general, hotplug 
or HAL? Why isn't there a policy file for gphoto, when there is an 
information file?

My system is the current Debian testing with a self-compiled kernel 
2.6.24.4.

Best,
Anton
