Description kaye gee 2004-08-24 09:01:31 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2)

Description of problem:
Gtkam reports an error when trying to add cameras.

Error message is "could not initialize camera"

Version-Release number of selected component (if applicable):
gtkam-0.1.12-2  using kernel-2.6.8-1.526

How reproducible:

Steps to Reproduce:
1. As a non-root user launch Digital Camera Tool:
2. On the menu bar click "Camera" and then "Add Camera"
3. Click "Detect" (Camera is detected)
4. Click "Apply" or "OK"

Actual Results:  gtkam returns error message

"Could not initialize camera"

Expected Results:  Camera should have been to gtkam

Additional info:

Camera type:  Canon 10D (using both PTP and Normal communication mode)
              Sony DSC-S75

NOTE:  Both cameras are detected and accessible when gtkam is launched
as root.
Comment 1 Tim Waugh 2004-08-24 09:28:32 EDT
This is not a gtkam problem but one of device permissions.  Which
device node does gtkam use for that camera?  If you aren't sure, you
can use 'strace -eopen gtkam 2>log' as root to find out.

Comment 3 Tim Waugh 2004-08-24 09:57:57 EDT
Okay, it's a USB device.  Please try this:

Unplug your camera
Log on as your own (non-root) user
Insert your camera
Try gtkam

Does that work properly?
Comment 4 kaye gee 2004-08-24 10:08:00 EDT
No the steps above produce the same error message.
  "could not initialize camera"
Comment 5 Tim Waugh 2004-08-24 10:44:39 EDT
What does 'rpm -V gphoto2' say?
Comment 6 kaye gee 2004-08-24 10:50:54 EDT
rpm -V gphoto2 retuns no value
Comment 7 Tim Waugh 2004-08-24 11:00:20 EDT
Are there any 'hotplug' messages added to /var/log/messages when you
unplug and re-insert the camera?

hotplug syslog entries
Comment 9 Tim Waugh 2004-08-24 11:20:21 EDT
This seems to be a hal problem then.  The /etc/hotplug/usb/usbcam
script is being ignored.
Comment 10 David Zeuthen 2004-08-24 15:14:18 EDT
This seems to me to be a hotplug problem.

patch for hotplug to give console permissions on hotplug

This patch should fix the problems.
Comment 12 Tim Waugh 2004-08-26 06:17:50 EDT
..and this file is provided by gphoto2, so it was a gphoto2 bug after
all.  Thanks, forgot about the path change. :-(
Comment 13 David Zeuthen 2004-08-26 06:20:27 EDT
Ah, my bad,

[david@laptop gnome-volume-manager]$ rpm -qf /etc/hotplug/usb/usbcam
[david@laptop gnome-volume-manager]$ rpm -qf

so both gphoto2 and sane-backends needs a bit of the patch each.
Comment 14 Tim Waugh 2004-08-26 06:25:58 EDT
Fixed packages are:

Comment 15 David Zeuthen 2004-08-31 12:30:21 EDT
Almost there, needs this patch against gphoto2
