Systemd developers seem to be unsure about this case subject too: https://github.com/systemd/systemd/issues/5642

@ettavolt

Thanks, the workaround did the trick, though now it's fixed :)

@Harvey

I removed the udev rule, updated the package and rebooted for good measure, now I can confirm it's working perfectly, so the suspicions may have been correct.

Thank you both!

@Sondeluz, sorry, I've copy-n-pasted != for the idProduct check in the proposed rule. It should have been

ACTION=="add" ATTR{idVendor}=="04f9" ATTR{idProduct}=="041f" ENV{libsane_matched}="yes"

Harvey commented on 2021-04-21 11:23

@Sondeluz: Please try again with -5 (Converted to uppercase as used in 20-sane.hwdb)

Sondeluz commented on 2021-04-21 09:29

Hello!

The command returns libsane_matched=yes

Yes, I am the only user on a Plasma/X session with systemd indeed.

I had no luck with the udev rule, the (same) error keeps appearing.

Oh, this is much better!

Thank you for testing the change, I'm sorry that it disrupted your system even though that everything is seem to be correct.

What does the following command return in your environment?

systemd-hwdb query usb:v04f9p041f

Just to reconfirm: when you try to scan, you're the only user in the system and have a graphical session, driven by systemd, correct?

For an immediate remedy I suggest creating /etc/udev/rules.d/20-dcp-l2510d.rules with the following contents:

ACTION=="add" ATTR{idVendor}=="04f9" ATTR{idProduct}!="041f" ENV{libsane_matched}="yes"

I'm planning to have a testing session myself in a couple of days, maybe I find the package bug actually. My suspicion is that we need uppercase HEX in the hwdb in contrary to rules…

Sorry! I wasn't specific enough. This comes directly from the desktop scanner application, the printer itself was and is working nicely using brscan4 on Fedora, for example. It's a DCP-L2510D connected via USB, nothing fancy.

Both skanlite, simple-scan and xsane report I/O errors since the update. Here's what simple-scan complains about for example when running it with --debug:

Sorry, we can't help you with the information you've provided. Our printers don't show anything like this on their dot-led displays. ☺

Maybe that is an error in the output of some application or service? Which one? How is it launched?

Sondeluz commented on 2021-04-19 20:17

I honestly fail to understand these changes, but if it is of any help, my printer now throws "Failed to open device 'brother:bus4;dev1': Error during device I/O." since the last update.

@applebloom recent version doesn't install anything /etc/udev, please update.
