# copy and modify udev example file to udev folder
sudo cp udev-example/55-libsane.rules /etc/udev/rules.d/
# restart udev service, than unplug and replug scanner
sudo service udev restart
# now this should run without sudo
scanimage -L
```

sudo apt install scanbd
# create script directory
sudo mkdir /etc/scanbd/scripts
# copy script
sudo cp scannerbutton.sh /etc/scanbd/scripts/

# copy modified plustek.conf
sudo cp scanner.d/plustek.conf /etc/scanbd/scanner.d/
# restart scanbd
sudo service scanbd restart
```
