Hello! I have this scaner and I see status support at this url as "untested". 
I check scaner with SANE and it works fine. Please see log.

[midnighter at localhost ~]$ scanimage --version scanimage
scanimage (sane-backends) 1.0.22; backend version 1.0.22

[midnighter at localhost ~]$ sudo scanimage -v -d genesys:libusb:002:010 --mode 
color --format=tiff > image.tiff

This is sane-find-scanner from sane-backends 1.0.22

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.
