Description Vytautas Liuolia 2004-12-27 08:07:46 UTC 
HAL device management daemon doesn't detect libgphoto compatible usb cameras as cameras, however, it finds the devices and lists them properly in hal-device-manager.



Reproducible: Always
Steps to Reproduce:
1. Use HAL daemon, gnome-volume-manager.
2. Connect PTP USB camera.

Actual Results:  
Nothing, except the camera was listed in hal-device-manager.

Expected Results:  
gnome-volume-manager should start the command I binded with cameras.

HOW I MANAGED TO FIXED THAT.

With the help of hackers on #gnome on irc.gimp.org, I heard that hal recognizes
cameras using libgphoto2.usermap. I made a symlink from usbcam-gphoto2.usermap
(this was installed by gentoo) to libgphoto2.usermap, and started to work!
So hal should be patched to know about usbcam-gphoto2.usermap.

Comment 1 foser (RETIRED) gentoo-dev 2004-12-28 06:58:32 UTC 
lqx can you comment on this ?

i was under the impression hal should pickup any *.usermap file.
Comment 2 foser (RETIRED) gentoo-dev 2005-01-16 12:56:31 UTC 
what is your hal version ? by looking at the code i believe this is already taken care of in recent versions .. could you please test that, remove the symlink you made (a bad idea anyway to alter stuff in /usr) & try it with current stable hal and current ~x86 hal if stable doesn't work.
Comment 3 Vytautas Liuolia 2005-01-16 13:50:24 UTC 
No, nothing helps.
My symlink is, as written, from /etc/hotplug/usb/usbcam-gphoto2.usermap -> /etc/hotplug/usb/libgphoto2.usermap.

When I remove the symlink, the bug emerges again.
Of course, I haven't forgot restarting hald, even tried rebooting the system.

Now I have latest system (just done 'emerge world'), using newest ~x86 hal.
Calculating dependencies ...done!
[ebuild   R   ] sys-apps/hal-0.4.5

When I have spare time, I will look to sourcecode myself, anyway, I think problem is clear -- hal knows about libgphoto2.usermap, but it doesn't know about usbcam-gphoto2.usermap.
Comment 4 Vytautas Liuolia 2005-01-16 13:56:24 UTC 
I forgot to add that all these tests with upgraded system were carried out on a brand new machine, different from the PII on which I discovered this bug.

So it's not related with the possible software/hardware problems on that pc.

Just in case, the info of the new pc:

Comment 5 foser (RETIRED) gentoo-dev 2005-01-16 13:59:49 UTC 
you say the link is from usbcam-gphoto2.usermap -> libgphoto2.usermap and next you say hal 'knows' about libgphoto2.usermap ?

The one thing i can see that the libgphoto2.usermap file is directly referenced in the source code and I don't really see why it doesn't get picked up like that.
Comment 6 foser (RETIRED) gentoo-dev 2005-01-17 05:22:02 UTC 
be clear on what you mean, because your comments make it actually more confusing than it is. Don't reply in private, reply here in the bug.

I added patch to hal-0.4.5-r1 that should fix this, please test.
Comment 7 Vytautas Liuolia 2005-01-17 06:52:08 UTC 
With the latest patch, it works.
Howerver, something must be done to avoid hardcoding paths.
