     9 # Note that for this script to work, you'll need all of the following:

    10 # a) a line in the file /etc/hotplug/usermap that corresponds to the 

    11 #    camera you are using. You can get the correct lines for all cameras 

    12 #    supported by gphoto2 by running "gphoto2 --print-usb-usermap".

    13 # b) a setup using pam_console creates the respective lock files

    14 #    containing the name of the respective user. You can check for that

    15 #    by executing "echo `cat /var/{run,lock}/console.lock`" and 

    16 #    verifying the appropriate user is mentioned somewhere there.

    17 # c) a Linux kernel supporting hotplug and usbdevfs

    18 # d) the hotplug package (http://linux-hotplug.sourceforge.net/)

    20 # In the usermap file, the first field "usb module" should be named 

    21 # "usbcam" like this script.
