Yes, this is what happens when you attempt to install some SCSI scanners
that are connected to a SCSI card. Tou often wind up needing to install up
to 8 instances of the scanner before the OS will recognize it. The
installation of each instance presents a "Windows has found New Hardware"
and there is an indication of an error at the end with the a repeat of the
"Windows has Found New Hardware" until the magic number of instances has
been installed. I think I refer to this in my second paragraph.
What I did not mention is that Microsoft at one point with XP was having an
argument with Adaptec and refused to license their SCSI layer files and
developed their own. The Microsoft layer software frequently would not work
well or reliably with some SCSI devices whose manufactures used the Adaptec
standards. I believe the two companies have now reconciled their
differences; but I believe that XP installs the Microsoft developed SCSI
layer by default and not the Adaptec one, which is one of the resons why
some scanners are not recognized under the "Scanners & Cameras" menu item in
the Control Panel but appear as a separate menue item such as "Unknown" or
"Imaging Devices". This sort of thing may be at the base of your problem;
but I am just speculating.

Install the scanner as a SCSI device rather than a USB device, this should
enable you to install the Epson SCSI drivers. They should remain installed
in XP until you manually remove them, which you will not be doing. Then
install the Epson scanner as a USB scanner which should cause Epson to
install the appropriate Epson drivers in XP, resulting in your having both
sets of drivers installed. I wouuld not use the Microsoft recommended "Let
Windows find the driver" option or install the drivers from the Epson CD (if
you can avoid it); but I would select to manually instal the drivers by
selecting the non-automatic option that Windows offers which will allow you
to search the CD for drivers to be installed manually.
