Trusty, scanner, workaround for error: [epson2] e2_ext_read: cancel request received

Asked by Katie Urey

This concerns setting up an EPSON Perfection 1650 Scanner to work with Trusty.

The scanner is recognized but xsane bails out with this error:

[epson2] e2_ext_read: cancel request received

I think I have the configs set OK and that this is a known bug. However, I have not found useful work-arounds.

Please send links to useful work-arounds..

many thanks,

Katie U

If you run:

sudo xsane

Does it work OK? Might be a permission issue on the scanner device...

Yes, it works when I run sudo xsane.

the hint took me to udev documentation.

I have changed a udev rule file in this directory

/lib/udev/rules.d

in this file
 40-libsane.rules

The stub of my scanner was listed. I removed the # comment from one line.
     grep -i -A1 'Epson Perfection 1650' /lib/udev/rules.d/40-*
          # /lib/udev/rules.d/40-libsane.rules:# Epson Perfection 1650 | Epson GT-8200U | Epson GT-8200UF
          /lib/udev/rules.d/40-libsane.rules:Epson Perfection 1650 | Epson Perfection 1650 PHOTO
          /lib/udev/rules.d/40-libsane.rules-ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0110", ENV{libsane_matched}="yes"

Then reloaded the udev rules.
             sudo udevadm control --reload-rules

the scanner then worked from my user account. It did complain when closing the program. This complaint went away when I forced a new ~/.sane directory to be created by renaming the old ~/.sane directory.

I had previously updated the /etc/sane.d/epson2.conf file ( the suggestion in 1565846)

So, I will mark this as resolved and send a Thank You!
