Tak Anders, jeg tror, at du er inde på sporet. Jeg har også en 
/etc/hotplug/usb/libusbscanner (se tekst under "underskrift"), hvor der står

# Sets up newly plugged in USB scanner so that the user who owns
# the console according to pam_console can access it from user space

Og ganske rigtigt: hvis jeg tager USB stikket ud og ind, virker den. 
Hvordan får jeg aktiveret dette uden "fysiske" handlinger ?? Jeg kører 
så vidt jeg kan se, ikke hotplug som deamon. Er det nødvendigt og i 
givet fald, hvordan gør jeg? Hotplug skal vist nok kaldes med nogen 
parametre.

# Sets up newly plugged in USB scanner 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.
# 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
# "libusbscanner" like this script.

if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
   # New code, using lock files instead of copying /dev/console permissions
   # This also works with non-gdm logins (e.g. on a virtual terminal)
