Still not working as normal user. It works for root, however, without

A reboot was not needed in my case. Let's check some permissions (this
is on my parents lenny where the scanner is installed):
$ ls -l /usr/bin/xsane # though I doubt these will be wrong
-rwxr-xr-x 1 root root 642500 2008-04-11 20:24 /usr/bin/xsane
$ ls -l /dev/bus/usb/001/
total 0
crw-rw---- 1 root root 189, 0 2008-04-27 11:57 001
crw-rw-r-- 1 root scanner 189, 1 2008-04-27 11:57 002
It looks like it is a permissions problem in /dev/bus/usb, but the udev
rule should take care of that, right? I have included output from
dmesg, listings from /dev/bus/usb, and excerpts from
/etc/udev/rules.d/libsane.rules.
From dmesg (so the scanner is at /dev/bus/usb/001/009?):
usb 4-1: new high speed USB device using ehci_hcd and address 9
usb 4-1: configuration #1 chosen from 1 choice
drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 9 if 1
alt 0 proto 2 vid 0x04B8 pid 0x0838
scsi7 : SCSI emulation for USB Mass Storage devices

scsi 7:0:0:0: Direct-Access EPSON Stylus Storage 1.00 PQ: 0 ANSI: 2
sd 7:0:0:0: [sda] Attached SCSI removable disk
But none of the devices in /dev/bus/usb are in groups scanner. All of
them have user root:root.
