I was finally able to get my USB Snapscan scanner to work as a user without having to disconnect and reconnect the device. I've attached the contents of /etc/security/console.perms
which i finally got configured correctly to handle setting permissions to /proc/bus/usb/00*/00*
# /etc/security/console.perms
#
# This file determines the permissions that will be given to priviledged
# users of the console at login time, and the permissions to which to
# revert when the users log out.
# format is:
# <class>=list of regexps specifying consoles or globs specifying files
# file-glob|<class> perm dev-regex|<dev-class> \
# revert-mode revert-owner[.revert-group]
# the revert-mode, revert-owner, and revert-group are optional, and default
# to 0600, root, and root, respectively.
#
# For more information:
# man 5 console.perms
# file classes -- these are regular expressions
<console>=tty[0-9][0-9]* vc/[0-9][0-9]* :[0-9]\.[0-9] :[0-9]
<xconsole>=:[0-9]\.[0-9] :[0-9]

i added /proc/bus/usb/00*/00* to the end of the <scanner> line
I also changed the permissions for scanner from 0600 to 0666 (but 0660 will probably also work)
Restarted my system, logged in as user and voila xsane came up perfectly.
Hope this is of some help to those other newbies struggling to get their devices configured correctly.
If you unplug or disconnect your device during the session you may have to add a chmod command to /etc/hotplug/libusbscanner in case permissions get reset... heres my copy of libusbscanner
#!/bin/bash
# $Id: libusbscanner,v 1.1 2004/05/04 13:05:27 twaugh Exp $
#
# /etc/hotplug/usb/libusbscanner
#
# 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)
# Idea and code from Nalin Dahyabhai <nalin@redhat.com>
if [ -f /var/run/console.lock ]
then
CONSOLEOWNER=`cat /var/run/console.lock`
elif [ -f /var/lock/console.lock ]
then
CONSOLEOWNER=`cat /var/lock/console.lock`
else
CONSOLEOWNER=
fi
if [ -n "$CONSOLEOWNER" ]
then
chmod 0000 "${DEVICE}"
chown "$CONSOLEOWNER" "${DEVICE}"
chmod 0600 "${DEVICE}"
chmod a+rw /proc/bus/usb/00*
fi
fi
