| Ecki | Half a year ago, I was fed up with windows and decided to install Xubuntu. I first tried a Live system of Focal Fossa, but couldn't use my printer, a HP Officejet Pro X451dw. | 06:42 |
|---|---|---|
| Ecki | I found out, that it worked well with Bionic Beaver, installed it and used it happily since then. | 06:42 |
| Ecki | Yesterday I decided to upgrade to Focal Fossa, because the support for Bionic Beaver will be cancelled soon, hoping that the problem might have been solved in the meantime. | 06:42 |
| Ecki | But unfortunately it was not. The system detects the printer, but I can't print and get the notification "printer not connected", which is not true. I disconnected and reconnected the USB cable to different USB slots, but the printer doesn't work anyway. | 06:42 |
| Ecki | I removed the printer and reinstalled it in the settings utility, but that didn't work. Finally I ran troubleshooting and got the following protocol: | 06:42 |
| Ecki | [03/Mär/2021:08:17:11] io/hpmud/musb.c 427: Found interface conf=0, iface=0, altset=0, index=1 | 06:42 |
| Maik | haven't you posted the same yesterday and got help Ecki? | 06:45 |
| Ecki | Yes, I did, but I can't find it. I thought, I was deleted, when I left this place. | 06:47 |
| Maik | since there's no one around (yet) with the knowledge to help, try asking on askubuntu | 06:49 |
| Ecki | Thank you. Can't we find an easy solution. Maybe I could use Focal Fossa, but install an older version of the printing program. | 06:50 |
| Maik | i'm not familar with such issues so i can't be of any help, sorry. | 06:52 |
| Ecki | Ok. I will stay here and hope, that someone comes by, who is an expert on the issue. | 06:53 |
| Ecki | I have asked the question at askxubuntu. | 07:22 |
| diogenes_ | Ecki, maybe try a different distro just as a test and only if printer is crucial. | 07:24 |
| Ecki | Thank you. Printing can wait until after easter, but then it will be crucial again. What can I understand by a "distro"? | 07:34 |
| diogenes_ | !distr | 07:36 |
| diogenes_ | !distro | 07:36 |
| ubottu | Other !Linux distributions besides !Ubuntu include: Debian, Mepis (using !APT); RedHat, Fedora, SUSE, Mandriva (using !RPM); Gentoo, Arch Linux, Manjaro, Slackware (using other packaging systems) | 07:36 |
| diogenes_ | a distro is a different operating system that is based on Linux distro is short for distribution. | 07:37 |
| Ecki | Well, I could reinstall Bionic Beaver. But it might be dangerous using it after the support has run out. | 07:37 |
| diogenes_ | yes but i mean other distros that are supported but which also include the older printer drivers. | 07:38 |
| diogenes_ | anyways gtg for awhile. | 07:38 |
| Ecki | Thank you. I will wait for a couple of days and hope, that sombody can help me, before I install a different distirbutioen. | 07:39 |
| krytarik | Ecki: From what information you gave so far, it could be LP bug 1871011. My mom was hit by it after upgrading from Bionic to Focal recently too - and we fixed it by the suggested workaround of removing the 'ippusbxd' package. | 15:07 |
| ubottu | Launchpad bug 1871011 in ippusbxd (Ubuntu) "USB scanning broken on focal by ippusbxd (was: hpmud and ippusbxd conflict)" [Undecided,Confirmed] https://launchpad.net/bugs/1871011 | 15:07 |
| krytarik | Btw, by the time I got online yesterday, you were already gone, so.. >_> | 15:10 |
| Ecki | Thank you, now I have something to read and something to try. But I am not an expert and it sounds complicated. | 15:16 |
| krytarik | Well, the specific command we've used is just "sudo apt purge ippusbxd" | 15:18 |
| krytarik | And iirc we just rebooted afterwards to make the module go away. | 15:18 |
| Ecki | So I just enter this in the terminal and restart the computer? | 15:33 |
| krytarik | Yeah, just with your admin password in between. | 15:34 |
| krytarik | Could also try something like "sudo rmmod ippusbxd" first rather than rebooting though. | 15:36 |
| krytarik | Oh right, it's a service rather than just a module, and the suggested command would have been rather finicky to figure out properly.. | 15:38 |
| krytarik | So yeah, just reboot. | 15:38 |
| Ecki | I have tried it and got an output including "the following packages have been removed: ippusbxd | 15:39 |
| Ecki | So I should have done it right, haven't I? | 15:39 |
| Ecki | I am going to reboot. Many thanks for your help. I might come back, if it doesn't help or new problems occur. | 15:44 |
| Ecki | Hi, it's me again. I have tried to solve the problem, that my HP Officejet Pro X 451dw won't print under Focal Fossa, though it is detected and though it did under Bionic Beaver. | 16:01 |
| Ecki | You suggested to remove the package ippusbxd to avoid a conflict about USB channels: | 16:01 |
| Ecki | I ran 'sudo apt purge ippusbxd' and it produced an output containing "removed packages: ippusbxd' | 16:01 |
| Ecki | I then ran 'sudo rmmod ippusbxd' and it producet an output, that said ippusbxd is not installed. | 16:01 |
| Ecki | I rebooted the computer, but the problem continues. I can't print not even a testpage and get the notification: ' printer not connected', which still is as wrong as before. | 16:01 |
| krytarik | Ecki: Yeah, the fact that you can re-add the printer to the system defeats that claim. Do you get any further error output than you already posted though? | 16:40 |
| Ecki | Wait a moment, I will run troubleshooting and show you the protocol. | 16:47 |
| krytarik | !paste | 16:48 |

| Ecki | It printed one testpage and no more and repeats: printer not connected | 17:03 |
| Ecki | Usually I could enter troubleshooting after trying to print a testpage, but this dialog doesn't open now. | 17:03 |
| Ecki | I have removed the printer again and reistalled it., hoping that I could enter troubleshooting this way, but I couldn't. | 17:05 |
| Ecki | I have sent 2 protocols of troubleshooting via https://paste.ubuntu.com . | 17:33 |
| Ecki | I have sent a screenshot of my teminal after running 'sudo apt purge ippusbxd' and 'sudo rmmod ippusbxd' to imgur; https://imgur.com/a/2MVUSMD | 17:49 |
