It seems the best solution for now is to add SANE_USB_WORKAROUND=1 line to /etc/environment:
echo "SANE_USB_WORKAROUND=1" | sudo tee -a /etc/environment (or to /etc/systemd/user.conf: echo "DefaultEnvironment=SANE_USB_WORKAROUND=1"|sudo tee -a /etc/systemd/user.conf ) For more info why SANE_USB_WORKAROUND=1 is needed look at http://www.sane-project.org release notes of 1.0.27: Note 3: The Linux USB3 workaround which was added in version 1.0.25 is now disabled by default. If you have difficulty using a scanner which previously worked, or intermittent scanner availability, try setting the new environment variable SANE_USB_WORKAROUND=1 before starting frontend.
