# Sets up newly plugged in USB camera so that just one certain user
|
|
|
|
USER=root
|
|
|
|
# can access it from user space. (Replace root by the user you want
|
|
# to have access to the cameras.)

# 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) run your camera software as the user given above
|
|
# c) a Linux kernel supporting hotplug and usbdevfs
|
|
# d) the hotplug package (http://linux-hotplug.sourceforge.net/)
|
|
# e) su
|
|
# f) env
|
|
# g) X11
|
|
#
|
|
# In the usermap file, the first field "usb module" should be named
|
|
# "usbcam" like this script.

# Script written by Trevor Woerner but slightly adapted for inclusion
