All I did (for the DX-9400F) was to unplug/plug it to get the device
node recreated. You might want to remove the static device node in
/dev/.static/ first.

Still not working as normal user. It works for root, however, without
needing the node in /dev/.static/dev. I hate to reboot. I like the
long uptime but we had a power outage recently, so I guess that really
isn't much of an issue right now.

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

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
usb-storage: device found at 9
usb-storage: waiting for device to settle before scanning
usb-storage: device scan complete
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.

I have added the line to /etc/udev/rules.d/z60_libsane.rules. Do I need
to reboot the system to get it recognized, or is there another way? Like
restarting a daemon, or something of that sort?

As my other post said, there were still permissions problems. I did a
reboot, however, and it did solve the problem. Maybe there is something
in Lenny, or Sid, that allows the udev rules to work without a reboot,
but this is not in Etch? In any case, it is working now. So I added a
similar rule in /etc/udev/udev.rules for my new camera that I could
access with gtkam as root, but not as a normal user, and rebooted
again. Lo and Behold, I can now access the camera as a normal user,
too! I am now a happy camper.
Thanks to all who helped me on both of these issues.
