USB scanning and printing broken on focal by ippusbxd (was: hpmud and ippusbxd conflict)

[Daniel Rodriguez]

SOLUTION : sudo apt remove ippusbxd

---- Initial report -----

On Ubuntu 20.04 focal (with -proposed enabled). HPLIP=3.20.3.

Previously there was a libmtp (udev) bug erroneously detecting HP printers as mtp devices. This was fixed. Now, I can try to scan-- from both simple-scan and hp-scan, hplip errors out:

Printer/scanner is an Officejet 4635. Scanning previously worked just fine a few months ago. Regression?

Upon plugging in the printer, there is a conflict between hpmud and ippusbxd (enabled by default?). ippusbxd wins, and thus claims the usb interface... blocking hpmud from working.

All I had to do to get scanning working again was `systemctl stop ippusbxd@(bus):(device)` and everything works again.

How can this be fixed?

[Till Kamppeter (till-kamppeter)]

Your printer got grabbed by ippusbxd because it supports the modern, driverless approach. HPLIP is not required for it any more. The printer should work with the "escl" SANE backend of SANE 1.0.29.

Please make sure your Focal system is completely updated.

If so, please enter the following commands and post the output here:

dpkg -l | grep sane

scanimage -L

[Bartosz Kosiorek (gang65)]

I have the similar issues with USB detection after upgrade to Ubuntu 20.04 on my scanners (HP Laser MFP 135a - smfp backend and HP OfficeJet 4630 - hpaio backend).
WIth

The hpaio scanner is detected on USB, but it is not able to communicate (xsane, scanimage, simple-scan). Only scanning by network is working correctly.

With HP Laser MFP 135a - smfp, it is not able to detect it on usb port.

I would like to investigate this issue further.
How did you enabled logs to investigate this issue?

[Robert Dinse (nanook)]

      I did not do anything special, I just grep'd the syslog it was there.

[Yvan Masson (yvan-masson)]

Same issue here with an OffieJet 5232. Unfortunately running systemctl to disable and stop ippusbxd@(bus):(device) is not working for me. Any help would be greatly appreciated.

[Till Kamppeter (till-kamppeter)]

Please uninstall ippusbxd. Then your device should work with HPLIP normally. ippusbxd wa supposed to allow driverless printing and scanning without HPLIP. Unfortunately there were problems in its design.

In Groovy we will replace ippusbxd by ipp-usb which finally allows driverless printing and scanning without HPLIP to work reliably.

See bug 1891157.

[Robert Dinse (nanook)]

      I did that before getting this e-mail. Actually I deleted EVERYTHING
relating to printing and scanning and installed hplip and other packages one
at a time until things worked again.

[Henrik R. (henrik-roseno)]

I cannot scan with Document Scanner on Ubuntu 20.04.1 with my HP Color LaserJet CM2320fxi MFP. It worked fine on Ubuntu 18.04.
I get the error "Failed to scan. Unable to connect to scanner".
Then I tried uninstalling ippusbxd using Synaptic Package Manager, disconnecting the printers from USB, deleting the printers in Settings -> Printers and then reconnect the USB and reinstall the printers. But scan still doesn't work.

[Henrik R. (henrik-roseno)]

I can add that after reinstalling the printer I tried the 2 Terminal commands mentioned above in comment #2:

henrik@henrik-thinkpad-20-04:~$ dpkg -l | grep sane

The ippusbxd grabbing the printer/scanner does not seem to be limited to HP, I had same with Canon LiDE 300 scanner and other scanners mentioned here: https://forums.linuxmint.com/viewtopic.php?f=51&t=329760

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Vincent Gerris (vgerris)]

I seem to have a similar issue with my HP ENVY 5544.
After removing ippusbxd and stopping the related service, my printer still does not print.
Dmesg shows this every time I press the test page button in either HP tools or Printers (GNOME GUI):

usblp1: removed

So it seems the device is removed everytime it gets a command.
The print job ends up in the queue but never gets processed, also not after reconnect.

[Vincent Gerris (vgerris)]

update: when I shut down the printer with the usb cable connected and then start it again it works.

[Lorenzo Novara (lornova)]

On a fully updated Ubuntu 20.04.3 LTS with kernel 5.11.0-37-generic #41~20.04.2-Ubuntu I'm experiencing the same issue with my HP OfficeJet 4657.

The workaround has been to remove IPPUSBXD:

sudo apt remove ippusbxd

Now I can scan again.

[Michel-Ekimia (michel.ekimia)]

We had several clients with HP printers that faced this problem.

This should really be fixed on LTS 20.04 as there is no simple workaround for the user

If ippusbxd is non functionnal I guess it should be removed on next 20.04.4

[Robert Dinse (nanook)]

      For what it's worth it's STILL broken on 21.04, but I fixed by grabbing
hplip from HP's website and installing via the provided shell script instead
of the broken version shipped with Ubuntu.

[Till Kamppeter (till-kamppeter)]

As ippusbxd by itself is broken, meaning that it even does not work very well with the devices it is actually designed for, I am also in favor of removing it from all still supported Ubuntu versions (especially LTS). Then it does not block devices which could otherwise work better.

To the users whose device needed ippusbxd we should tell to install the ipp-usb Snap then, at it does the task of supporting IPP-over-USB devices correctly and to their full extent.

ipp-usb Snap:

https://snapcraft.io/ipp-usb

ippusbxd replacement by ipp-usb:

https://github.com/OpenPrinting/ippusbxd#before-you-begin-ippusbxd-or-ipp-usb

[Robert Dinse (nanook)]

      Why not just distribute the working version? The problem with snaps
is they screw the functionality of shared libraries wasting memory.

[Till Kamppeter (till-kamppeter)]

The problem is that we cannot add a new package to an already released Ubuntu. A SRU (Stable Release Update) can only be bug fixes on already included packages, no new feature releases of them, nor completely new packages.

@Till: Would using the backports pocket be possible? If you backport a package to a release where it doesn't exist in the -release pocket, it effectively works as an SRU.

[Robert Dinse (nanook)]

      Well, I will just live with installing the package from HP
directly then, I don't like snaps, I disable them on my systems.

@Robert : you misunderstood , the problem is not the version of the HPLIP , but the conflict with ippusbxd on USB device claiming.

Auto configure usb printers is nice but we can live on 20.04 without it.

[Robert Dinse (nanook)]

      Ok, well I do not understand, I just know my HP printer stopped working
when I upgraded to 21.04, and installing hplip from HP directly made it work
again.
