Hotplug, digikam, usbcam, Slackware 11.0 problem


I have had digikam working fine in slackware 10.2 using 2.4 and my compiled 2.6 kernel.

Now using 11.0 with the 2.6-smp kernel I can only see my digital camera with root.

With the usbcam script in /etc/hotplug/usb/ there is supposed to be a file created in /proc/bus/usb/001/ with the right permissions. The file appears as owner root, group wheel which is not wha I need.

I might be doing something wrong but is it possible that there is a hotplug error with this kernel?

Look in /etc/rc.d/rc.udev where usbfs is mounted and change the devgid to something besides 10.

Code:
# Mount usbfs:
if ! grep -wq usbfs /proc/mounts ; then
   if [ -d /proc/bus/usb ]; then
       mount usbfs -t usbfs /proc/bus/usb -o devgid=10,devmode=0664
   fi
fi
This is what mine looks like. Also you could just add your user to the wheel group.

I'll give it a try

Searching the forum has thrown up this post

http://www.linuxquestions.org/questi...digikam+usbcam

rignes suggests that due to an update to current where hotplug is not run when using a 2.6.x kernel in conjuntion with udev his digital camera stopped working in digikam. This might make sense. Perhaps hotplug is not running so the usbcam script is not run and permissions are set. TAquaredF had a solution which I shall try tonight.

Udev sets the permissions. Create /etc/udev/rules.d/libgphoto2.rules file :

Code:
# Canon PowerShot A95 (normal mode)
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="30bb", MODE="0660", GROUP="users"
idVendor and idProduct for you cam can be found in usbcam.usermap.

Thanks all.
I tried /usr/lib/libgphoto2/print-camera-list udev-rules > camera.rules and put that in rc.udev
The file in /proc/bus/usb was created with the right group but it still did not work.
I tried Rauol's advise and added
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="3058", GROUP="users"
to 10-udev.rules and it's working!

Raoul,

What would the purpose of MODE="0660" be?

Thanks

Its like chmod : read and write for owner and group, nothing for others. So the cam will belong to root and be in the users group.
