Yes.  That doesn't seem to do any good, Laurie.  However, In trying this
again to be sure, I decided to turn off the scanner and then turn it
back on.  On the third try it recognized it.  One other thing I should
point out.  When I first turn on the scanner, this is after the computer
has been turned on for the day, the scanner drivers are reinstalled -
"Windows has found new hardware" routine.  Almost every time there is an
indication of an error in the installation at the "Finish" applet.  This
is the only device that want to reinstall itself upon first use each
day.  You may be right about it "spoofing the SCSI drive through the USB
port.

I'm not sure how to do that.  Epson packages all the drivers for a
specific machine into one compressed file.

I think that's what may be happening.  I usually forget to turn off the
scanner before I shut down the computer.  Come to think of it, this also
happens sometimes when I leave a CF card in the reader - and if I delete
the images on that card and do not remove it, the computer get upset
over a drive not being right.
