I'm getting closer!

I followed the instructions in libusb.html and found I had to make the
two changes.  First, there is no file /etc/hotplug/usb.usrmap but there
is a file /etc/hotplug/usb.distmap which contains the described scanner entries and I added a new one for my epson scanner.  Second, I had modify the script to change the permissions from 660 to 666.  Even with these changes xsane cannot find the scanner immediately after the system has been re-booted but only after the scanner has been disconnected and reconnected.

I don't mean to complain, in fact, I am very greatful for all the help
as I would never have been able to puzzle this out by myself.  Also, I
understand the reasons for switching from a kernel scanner module to the
libusb scanner support.

This said, I do wonder how a poor soul who just wanted to use a Debian
desktop would manage.  When I first tackled this problem I checked the
kernel-source-2.6.8 Documentation files and found nothing on usb
scanners, no note as to why the scanner module had been removed.  When I
was refered to the sane-usb documentation there was a note that
libusb-0.1-6 was required while apt-cache search shows only libusb-0.1-4
and libusb-dev which is reported as Version 1:0.1.5-4.  This is all
there was so this is what I used.  Finally, as noted in this and my
previous posting I had to make a number of changes to get the scanner
working again.  In contrast, when I compiled a kernel from
kernel-source-2.4.26 with the scanner module the scanner worked
immediately after system bootup.

Again, many thanks for all the help.  I love Debian and have great
admiration for all the experts who patiently respond to questions posted
on this user's list.  I hope to see Debian become the desktop of choice.
