20.04.2 does not connect HP OfficeJet Pro 7740 scanner via USB2

[Robert Pearson]

I am trying Ubuntu MATE 20.04.2 to see what works and what is broken.

My scanner is an HP OfficeJet Pro 7740 scanner connected to my ASUS A88XM-A motherboard via USB2 cable.

With previous releases, I use VueScan Pro. Work fine. With 20.04.2 it cannot find my scanner at all. I tried the bundled Document Scanner app. It finds the scanner but cannot connect to it to actually scan.

Apparently, something is wrong with connecting a scanner with a USB cable.

If you need more information, please tell me how to get it and send it to you.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Bug reporting is mostly about finding & fixing problems thus preventing future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709

You've tagged the issue relates to a release-upgrade from one release to another, eg. 19.10 to 20.04, or 18.04 to 20.04, but you see to be running the same 20.04.2 you installed so haven't used the ubuntu-release-upgrader yet. I'll switch package to 'linux' (ie. kernel) but I suspect you'd benefit more from support.

The Ubuntu-MATE community discourse can be found at https://ubuntu-mate.community/ where help can also be sought.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1940724

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.
