I found a solution and I have posted it at
http://gentoo-wiki.com/Talk:HOWTO_Install_a_USB_scanner#.22The_above_udev_rules_are_wrong..22.
If anybody who knows their hotplug and udev stuff better than I do could
take it upon themselves to correct the usb scanner howto itself
(http://gentoo-wiki.com/HOWTO_Install_a_USB_scanner), which is very
confusing and misleading, I'm sure there will be good few people out
there who will be very grateful to you. (And not just Gentoo users --
there is a real lack of up-to-date usb scanner documentation out there.)

Unfortunately I haven't been able to find a howto that explains clearly
how you are supposed to get permissions sorted out using hotplug with
more recent 2.6 kernels. There's something about a script in
/etc/hotplug/usb, but nothing I can find that tells you what you are
supposed to do with it.
The scanner works fine when run as root.
The permssions of the usb device (/proc/usb/001/004 right at the moment)
are
-rw-rw root:scanner
However, even though user robert is a member of group scanner, he can't
get sane even to recognise the scanner. He can do it though if he chmods
to root:users or root:audio or to most of the other groups he is a
member of. On the other hand there are some other groups of which he is
a member which don't seem to be able to access the scanner -- floppy and
adm for instance.
Does anyone have any idea what I'm doing wrong?
