simple scan & Epson perfection V100

[Grizzly]

After the tghread on scanners a while back 

I "thought" it was going to be plan sailing, ran Simple-Scan from terminal, it 
sees a scanner and knows it's an Epson, wants drivers & gives a link to epson 
support

After that a bit of a run around you find

https://download2.ebz.epson.net/iscan/plugin/gt-s600/deb/x86/iscan-gt-s600-bundl
e-1.0.0.x86.deb.tar.gz

download and install but Simple Scan still thinks no drivers are installed

Where did I go wrong?
