Device driver for Epson V600 Perfection

I have downloaded Epson’s iscan-bundle-1.0.0-x64.deb and run
sudo ./install.sh. The script runs without errors. However, the device driver does not get installed. As a test I ran Simple Scan and it says to install the device driver. Iscan says it cannot send commands to the scanner.

What am I missing?
Thanks,
Hugh
