Excellent! This will save me a great deal of trouble. However...

With Kernel 2.6.13-1.1526_FC4 it seems to take a long time
for the module to load. With 2.6.12-1.1456_FC4 it took maybe
a minute or two, which was longer than with previous
versions of the module, but with the 2.6.13 it seems to be
going for a record: I got bored and went away, but my prompt
records the time:
12:05:57$ sudo modprobe epst
and yes, I did press return before running modprobe, so it
really did take fifty minutes!
The scanner is an HP Scanjet 5100C, the log reports:

A gap of about fifty minutes between the "ppSCSI
... installed" message and the epst message seems fairly
repeatable (not, obviously, that I've tried it many times).
Once epst gets going it seems to work fine.
Do you have any suggestions?
