Another way to get info is to power on the scanner and plug it in, then
`modprobe -r` the appropriate kernel module(s) and then modprobe them
while doing `tail -F /var/log/messages`.  The kernel (udev) will create the
appropriate /dev entries upon successful modprobe.

In order for your user to be registered as a member of a group you have
to log completely out (including your X session) and back in.  You can
verify your group memberships with the groups command.  Judging from
what you've said I bet it was merely an issue of adding your user to the
scanner or usb group.  My experience with usb scanners is they generally
just work whereas when I start up my SCSI scanner I always have to
remodprobe the kernel drivers and then `chown :scanner /dev/sg?  &&
chmod 0770 /dev/sg?`, but there's probably a better (right) way to do
that. :-)
