From README file in the esci-interpreter-perfection-v330-1.0.0.rpm,

"    This plugin converts between the native protocol of the supported
    devices and the ESC/I protocol.  The latter protocol is supported
    by the SANE 'epkowa' backend, part of Image Scan!, and some other
    SANE backends.  However, only the 'epkowa' backend provides the
    hooks needed to use this plugin."

I do not think it works. The scanner itself needs binary firmware to start.

My first try after buying the scanner is to use it as is with the default 
sane-backends-iscan from Mageia Linux. It did not work.

Best regards,
