please also attach an appropriate part of a journalctl output
I would prefer an other approach to drill down into involved details. I have added the following specification to the discussed addition actions in the configuration files "/usr/lib/udev/rules.d/50-udev-default.rules" and "/usr/lib/udev/rules.d/70-printers.rules". , RUN{program}+="/bin/bash -c 'my_log=/tmp/log938659.txt && /usr/bin/date -Ins
$my_log && echo configure-%p >> $my_log && /usr/bin/ls -l /dev/bus/usb/$env{BUSNUM}/$env{DEVNUM} >> $my_log'"
The specified log file contains information like the following after I restarted "systemd-udevd.service" and switched my printer on again. 2015-07-23T16:37:59,712732516+0200 lp-/devices/pci0000:00/0000:00:02.1/usb1/1-2 crw-rw---- 1 root users 189, 4 Jul 23 16:37 /dev/bus/usb/001/005 2015-07-23T16:37:59,729717592+0200 configure-/devices/pci0000:00/0000:00:02.1/usb1/1-2 crw-rw---- 1 root users 189, 4 Jul 23 16:37 /dev/bus/usb/001/005 (In reply to Dr. Werner Fink from comment #29)
ENV{ID_USB_INTERFACES}=="*:0701??:*", MODE:="0664", GROUP:="lp"
that means with colon a later override will be avoided
The specified log file contains information like the following after another restart of udevd and my printer. 2015-07-23T16:45:52,895724921+0200 lp-/devices/pci0000:00/0000:00:02.1/usb1/1-2 crw-rw-r-- 1 root lp 189, 5 Jul 23 16:45 /dev/bus/usb/001/006 2015-07-23T16:45:52,907780826+0200 configure-/devices/pci0000:00/0000:00:02.1/usb1/1-2 crw-rw-r-- 1 root lp 189, 5 Jul 23 16:45 /dev/bus/usb/001/006 Does such a debug display mean that the setting of device file permissions by the udev assignment key "GROUP" alone is fragile on my Tumbleweed system in the shown constellation so far? -- You are receiving this mail because: You are on the CC list for the bug.
