# 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-camera-list usb-usermap usbcam
|
|
# 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.
