Nothing 'should' need modifying there. Suggest you revert to the original.

Your model is listed as supported by sane without mention of issues.
Search results show few complaints...

Three support choices:-
; run with sane - what's your DE, do you have libsane-extras installed?
does lsusb detect it (or are you using the SCSII connector)?
what front-end are you trying to use?

; use the (closed source) Epson recommended drivers for that device
(ImageScan) this should include the Kowa front-end for negative scanning:-

; use commercial product VuScan:-

That scanner doesn't require lp group membership.

I gave my Epson (Perfection 1240) scanners away and replaced with
different brands so my memory is dim, but I'm certain that support under
Lenny and Sarge was simpler than Agfa Snapscans.
NOTE: the buttons on the scanner don't work by default under sane - but
it is possible to get them working.
