[Bug 1940724] [NEW] 20.04.2 does not connect HP OfficeJet Pro 7740 scanner via USB2

[Robert Pearson]

Public bug reported:

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.
