- # Sets up newly plugged in USB camera so that the user who owns
- # the console according to pam_console can access it from user space
- #
- # Note that for this script to work, you'll need all of the following:
- # a) a line in the file /etc/hotplug/usermap that corresponds to the
- # camera you are using. You can get the correct lines for all cameras
- # supported by libgphoto2 by running "print-usb-usermap".
- # b) a setup using pam_console creates the respective lock files
- # containing the name of the respective user. You can check for that
- # by executing "echo `cat /var/{run,lock}/console.lock`" and
- # verifying the appropriate user is mentioned somewhere there.
- # c) a Linux kernel supporting hotplug and usbdevfs
- # d) the hotplug package (http://linux-hotplug.sourceforge.net/)
- #
- # In the usermap file, the first field "usb module" should be named
- # "usbcam" like this script.

- # New code, using lock files instead of copying /dev/console permissions
- # This also works with non-gdm logins (e.g. on a virtual terminal)
