I’ve an HP DeskJet 2630 multi-function printer, use that with usb cable. I installed sane-backend and cups to use the printer, for settings I read README files of these packages:
chown _cups:_saned /dev/ugen0.* /dev/usb0 chmod 660 /dev/ugen0.* and added my user to the _saned group. However the scanning (sane-find-scanner) doesn’t work with my user, nor as _saned user, until I set the permissions to /dev/usb0 as well. Can you confirm this? Should the README files be updated from “chmod 660 /dev/ugen1.*” to “chmod 660 /dev/ugen1.* /dev/usb0” ? -- kikadf
