Here is the systemd journal of plugging the printer, taken with journalctl -o verbose -f 2>&1 | tee systemd-journal-plug.log After issuing the command (with printer unplugged) I waited some seconds to see that there is no further output happening. Then I plugged the printer and waited for no further output happening again and stopped the command with Ctrl+C.

[Bug 1721839] Re: Services asked for by UDEV do not get triggered
I have tried recording startup and shutdown now by recording with the command "sleep 10" and doing the manual operation (plugging/unplugging USB) during the sleep delay. Unfortunately, it does not work. For unplugging I did sudo umockdev-record --ioctl=/dev/bus/usb/002/009=deskjet-2540-ioctl- shutdown.log sleep 10 and unplugged the USB plug right after pressing Enter. After waiting for the command to exit I did not get a deskjet-2540-ioctl-shutdown.log file. For plugging I did sudo umockdev-record --ioctl=/dev/bus/usb/002/010=deskjet-2540-ioctl- startup.log sleep 10 with the intention to plug the printer right after issuing the command. Note that after repugging the printer will appear under Bus:Device 002:010 so I used /dev/bus/usb/002/010. As the printer is still unplugged when issuing the command there is not yet a /dev/bus/usb/002/010 file and the program exists immediately complaining because of that and does not run "sleep 10". So any help to record start-up and shutdown of a USB device is appreciated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1721839 Title: Services asked for by UDEV do not get triggered To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1721839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1721839] Re: Services asked for by UDEV do not get triggered
I have looked through Pitti's (upstream author) instructions of the tool, ut it seems that it only works on the already running device and that there is no way to capture the startup and shutdown sequences. I have recorded the main record of the device this way: till@till-x1carbon:~$ lsusb [...] Bus 002 Device 009: ID 03f0:c211 Hewlett-Packard [...] till@till-x1carbon:~$ sudo umockdev-record /dev/bus/usb/002/009 > deskjet-2540.umockdev I have attached the file. One can record device operations, but only those which can get triggered by a shell command, not those who are triggered by a manual operation on the device (plug/unplug, power-cycle, press button, ...). Is there a shell command which triggers a shutdown, start-up, or reboot of the printer? Especially one has to take into account that the device keeps only its bus ID and the device ID increments by 1. @pitti, is there a way to record start-up or shutdown of a USB device? ** Attachment added: "deskjet-2540.umockdev" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1721839/+attachment/4967899/+files/deskjet-2540.umockdev -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1721839 Title: Services asked for by UDEV do not get triggered To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1721839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is not critical. The service is started, but the encoding/decoding of the %i name appears to be not round-trip safe. ** Changed in: systemd (Ubuntu) Importance: Critical => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1721839 Title: Services asked for by UDEV do not get triggered To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1721839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1721839] Re: Services asked for by UDEV do not get triggered
It seems that with a 70-printers.rules as follows at least a correct
service name is generated
--
# Low-level USB device add trigger
ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device",
ENV{ID_USB_INTERFACES}=="*:0701??:*", TAG+="udev-configure-printer",
TAG+="systemd", PROGRAM="/bin/systemd-escape
--template=udev-configure-printer@.service %p", ENV{SYSTEMD_WANTS}+="'%c'"
# Low-level USB device remove trigger
ACTION=="remove", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device",
ENV{ID_USB_INTERFACES}=="*:0701*:*", RUN+="udev-configure-printer remove %p"
--
Note that in the first rule the systemd-escape command has NO "-p"
option and that the %c for ENV{SYSTEMD_WANTS} has extra single quotes.
Compared to the original file only these single quotes got added.
After restarting UDEV with
sudo udevadm control --reload
and re-plugging the printer in most cases the service does not get
started.
systemctl status 'udev-configure-printer@-devices-
pci:00-:00:14.0-usb2-2\x2d2.service' > status.txt
gives something like
--
● udev-configure-printer@devices-pci:00-:00:14.0-usb2-2\x2d2.service -
Automatic USB/Bluetooth printer setup
(devices-pci:00-:00:14.0-usb2-2\x2d2)
Loaded: loaded (/lib/systemd/system/udev-configure-printer@.service; static;
vendor preset: enabled)
Active: inactive (dead)
--
In such a case one can start the service manually with
sudo systemctl start 'udev-configure-printer@-devices-
pci:00-:00:14.0-usb2-2\x2d2.service'
and this starts correctly udev-configure printer which sets up the
printer (and starts ippusbxd if needed).
In some very few cases the service actually gets correctly started (and
the printer set up) when one plugs the printer, but this happens rarely
(can there be some kind of race condition?).
So this only rarely happening automatic start of the printer setup
service is now the problem. The escaping seems to be fixed by the extra
single quotes.
