ippusbxd crashing on boot up in Focal Fossa

[Andy C]

ippusbxd 1.34-2 crashes on system boot in Focal Fossa Ubuntu 20.04. Kernel 5.4.0-29.
ippusbxd also crashes when booting from an install media USB Stick (Ubuntu 20.04).
This occurs on Desktop PC and laptops connected to an HP Envy 6200 series Printer via USB cable.
Disconnecting the USB cable to the printer, the crash does not occur on boot up.
Earlier releases of Ubuntu (eg 19.10 and 19.04) boot cleanly.

Work-around, if printing over LAN is not required, is to mask the ippusbxd service in systemctl:

sudo systemctl mask ippusbxd@001:003.service *
sudo systemctl mask ippusbxd@.service

and remove crash logs in /var/crash

* check your bus/device nos via :
systemctl --failed

Thanks, Sebastian, the apport report has been uploaded.
~ FYI my first attempt to log the bug got rejected (not authorised) when:
  - I ran <ubuntu-bug ippusbxd> from AltF2 (which does create the data you need, right?)
  - And attempted to upload the /var/crash log. Is that not allowed?
So I tried later on filing the bug directly, which did work...
I don't do this stuff often enough to learn the in's and outs ;-0

[Andy C (tunggft)]

Attach crash log.

[Andy C (tunggft)]

Updated details. I can confirm this issue is not isolated to one PC.
Same issue occurs on 2 other laptops, when they are connected by USB cable to HP Envy 6200 series printer.

Backtrace output of the CoreDump in the attached crash report file. ippusbxd and ippusbxd-dbgsym packages must be installed.

Thanks Till, I'm assigning the bug to you
