I don't know about such a model.
Up to now I only know about an "Epson Perfection 4990 Photo".

Which 3 _files_?
I guess you talk about RPMs?
If yes, which exact RPM package names?

As an "Epson Precision 4990 Photo" is neither listed in YaST
nor can be found via http://www.sane-project.org/cgi-bin/driver.pl
you must have got this information from somewhere else.

Did you read the info about "iscan" on 64-bit hardware in YaST?

For example the "Epson Perfection 4990 Photo" is shown in YaST
with driver "epkowa" and the info shows "requires DFSG non-free
iscan-plugin-gt-x750" and when you try to set it up in YaST,
it shows this message:
---------------------------------------------------------------
The package iscan should be installed but it contains
proprietary binary-only i386-only software.
Therefore it is only available for i386-compatible
architectures and it may cause problems on AMD 64-bit
(x86_64) systems.
---------------------------------------------------------------

The "DFSG non-free iscan-plugin-gt-x750" is provided in the
package iscan-proprietary-drivers and the RPM info is
---------------------------------------------------------------
Proprietary Driver Libraries for Image Scan for Epson Scanners
The proprietary binary-only i386-only libraries are provided
(in object code form only) ...
---------------------------------------------------------------

This means that the iscan-plugin-gt-x750 doesn't work on
a plain 64-bit system - it might work if all required
32-bit libraries are installed on your 64-bit system
and it should work if you install a 32-bit openSUSE on
your 64-bit hardware.

The plain iscan (without a iscan-plugin-*) should work
o.k. on a 64-bit system if all required 32-bit libraries
are installed (in particular sane-backends-32bit.rpm)
but I don't know the exact details for each possible case
when which of these proprietary driver stuff works or fails.
Therefore I don't want to show an ultimate "this device
does not work on your system" message in YaST.
