You will need to emerge hotplug if you haven't already.
Then
1. Add a line to /etc/hotplug/usb.usermap (this should be two seperate lines):
# usb module match_flags idVendor idProduct bcdDevice_lo bcdDevice_hi
bDeviceClass bDeviceSubClass bDeviceProtocol bInterfaceClass
bInterfaceSubClass bInterfaceProtocol driver_info
scanner 0x0000 0x04a9 0x2207 0x0000 0x0000
0x00 0x00 0x00 0x00 0x00
0x00 0x00000000
where 0x04a9 is the vendor ID of your scanner and 0x2207 is the product ID of
your scanner. I'm not sure what the value of match_flags should be but 0x0000
works for me.
2. Create a script /etc/hotplug/usb/<usb module> where <usb module> is the
same as the first field of the line you added to /etc/hotplug/usb.usermap
above:
#!/bin/bash
#
# This is a copy of /etc/hotplug/usb/usbcam
#
# $Id: usbcam.console,v 1.4 2002/09/12 16:50:18 hun Exp $
#
# /etc/hotplug/usb/scanner
#
# 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. You can get the correct lines for all cameras
# supported by libgphoto2 by running "print-usb-usermap".
# 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
# "scanner" 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 <[EMAIL PROTECTED]>
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 0666 "${DEVICE}"
fi
fi
I've set permissions to 666 since my box is only running when I am using it
and my usb devices are always plugged in at boot.
3. Restart hotplug.
