 # HPLIP udev rules file. Notify console user if plugin support is required for this device.
 
+# SUSE changed:
+#
+# MODE="0660" to MODE="0664"
+# because it is sufficiently secure to let any user read the device nodes
+# because HPLIP opens the device nodes exclusively so that sniffing
+# of print jobs or scanner image data should not be possible.
+#
+# Exchanged the rule to GOTO hpmud_usb_rules if SUBSYSTEM is "usb"
+# with the rule if SUBSYSTEM is "ppdev" to avoid that the "ppdev" rule
+# is needlessly processed when SUBSYSTEM is "usb".
+#
+# Added rules to skip the hpmud_usb_rules rules via GOTO hpmud_rules_end
+# if SUBSYSTEM is not "usb" or if ENV{DEVTYPE} is not "usb_device"
+# to avoid that the hpmud_usb_rules are needlessly processed.
+#
+# The rule to automatically "add the printer and install plugin" is disabled
+# because automated installation of non-free proprietary third-party software
+# (here the plugin from HP) should not happen and it can cause whatever kind
+# of strange behaviour see for example https://bugs.launchpad.net/bugs/1197416
+# while in contrast manual printer setup via hp-setup usually "just works"
+# and it is clear for the user what goes on and in case of failure what went wrong.
