Epson V350 Scanner on Ubuntu 17.10

  • 772

I've tried everything that I can find to get my scanner working again. It worked fine with 16.04 and now that I've upgraded to 17.10 I can't get it working again. I know that I had problems before, but having tried every solution that I can find on the web, I'm going to ask here for help.

The device is plugged in via a USB hub (I've tried everything directly too) but whilst I can find it in devices, it won't run with iscan or xsane.

lsusb can see it Bus 003 Device 009: ID 04b8:012f Seiko Epson Corp. GT-F700 [Perfection V350]

All help gratefully received.

  1. I have the same problem, but I've found a more-or-less working solution, I post it here so maybe someone could improve it.

    It works with xsane, not with iscan.

    What happens is that it takes a lot to start and the preview window shows up blank.

    So:

    • I've added in the file /etc/sane.d/epkowa.conf the line

      usb 0x04b8 0x0131

      where the codes are taken from lsusb

    • (I know very little about udev rules) I've added a file /etc/udev/rules.d/80-epson.rules

      ATTRS{idVendor}=="04b8",ATTRS{idProduct}=="0131",ENV{libsane_matched}="yes"

      ENV{libsane_matched}=="yes",RUN+="/bin/setfacl -m g:scanner:rw $env{DEVNAME}"

    • my user is clearly in the group scanner.

      And I launch xsane with a LIBRARY_PATH (modifying ld.so.conf.d messes up everything)

      LD_LIBRARY_PATH=/usr/lib/sane xsane

    • So after some time (200 secs) an xsane dialog windows pops up, I choose the third line (the one with the name of the scanner):

      xsane dialog window

    Finally xsane starts, sometimes with a uncomplete preview window (blank with no button or frame to set), but it works.

    Hope it helps.
