Comment # 4 on bug 975866 from Mark Misulich

I am having the same problem with an Epson Perfection V500 Photo scanner, the
scanner doesn't work.  It worked perfectly with my older computer, and when I
attached it to a newer computer that I built, the driver Epkowa doesn't
recognize the scanner.  

I installed various versions of the iscan-bundle up to 1.0.4, but none of them
allow Epkowa driver to recognize the scanner.  I also tried using the demo
version of Vue-Scan, but it also reports that it can't recognize any scanner. 
I have tried versions 1.0.24, 1.0.25, and 1.0.27 of sane-backends, and these
haven't worked to allow the scanner to be recognized by yast.  I have tried to
use the USB workaround, but that didn't allow the scanner to work.

The computer is a dual-boot with Win7, and the scanner works well with Win7 and
the Epson driver software.

My purpose in adding my comment to this thread is in the hope that this will
motivate the software writers to fix this bug to once again allow my scanner to
be used with my new computer.

My new computer that is having the problem with the scanner is built with an i7
3.6 GHZ Kaby Lake processor, and a Gigabyte B250M-DS3H Motherboard.
