I do not see where data/rules/56-hpmud_sysfs.rules gets installed into the system.
Can you run grep hpaio /*/udev/rules.d/* and post the output here? For each resulting file, can you run dpkg -S <file> If you remove the hpaio line from /etc/sane.d/dll.conf does scnbd return to work? If you unplug and re-plug your HP device, does the "hpaio" line re- added? Does one of the resulting files of the search above contain a line like ENV{sane_hpaio}=="yes", RUN+="/bin/sh -c 'grep -q ^#hpaio /etc/sane.d/dll.conf;if [ $$? -eq 0 ];then sed -i -e s/^#hpaio/hpaio/ /etc/sane.d/dll.conf;else grep -q ^hpaio /etc/sane.d/dll.conf;if [ $$? -ne 0 ];then echo hpaio >>/etc/sane.d/dll.conf;fi;fi'" which one(s)? To which package does it belong ("dpkg -S <file>")? ** Changed in: hplip (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1560388 Title: hpaio entry added automatically to /etc/sane.d/dll.conf Status in HPLIP: New Status in hplip package in Ubuntu: Incomplete Bug description: When plugging in my HP Officejet 6210 via USB an entry "hpaio" is added to /etc/sane.d/dll.conf.
