Hi. I have a Panasonic KX-MB1500 (printer+scanner). The printer drivers and the printer itself are installed and work for me without problems. But with the scanner, I had to dig around manually all the time (60-libsane.rules). Yesterday I spat on this matter and made a SrEditor. Now my problem with the scanner has disappeared.
SrEditor allows you to automatic add and apply rules for scanners that are not in the list of /etc/udev/rules.d/60-libsane.rules in one click. At the first start, it shows a list of USB devices connected to the computer. Selecting entries in the list with the mouse, the search result will be displayed in field (2): if the device (its vendor and product number) is not in the list of rules, it offers to insert a ready-made rule containing idVendor and idProduct. We find the necessary scanner in the list, press the "+" button and after restarting we get a device available for XSane. If something is wrong, you can always roll back to default by pressing the next button. Do not forget to include the user in the usb group.
Maybe it will also be useful to someone:
