@Hanisch ok in the epsonscan2 list of supported is:
" Perfection V19 Perfection V33 Perfection V330 Photo Perfection V37 Perfection V370 Perfection V39 Perfection V550 Perfection V600 photo Perfection V800 Photo Perfection V850 Pro RR-600W ST-2000 "
not a V200 to be found. still I wonder if it would work? it's just an easy install and remove.
but your homework has been better than mine---SORRY for all the bum steers.
at EPSON for your V200 they DO DO DO rec the Iscan package...and offer it not only DEB/RPM but SOURCE:
inside the source is
se the install.sh? worth a try. it's distro-agnostic and I've muscled in brother stuff this way although not my preferred method...
i gotta get up early tomorrow or I'd search engine 'v200 linux perfection' stories.
I'm not sold you need the plugin/right folders/move/copy nightmare yet. it's so barbaric and 2019...but all you can do is try.
