Power on scanner
Install xsane,sane-backends,libusb,libusb-compat,usbtools,usbutils
Menu/System tools/Hardware detection and drivers
Click on Scanner button
My scanner did not show in list, so I enter for none in my setup
Now I see scanner device listed in purple text

If you run under another user name that user can't scan until you add them to scanner group
