[REGRESSION] Bug 217353 - Logitech MX Anywhere 3 scroll wheel works incorrectly over USB dongle

From: Linux regression tracking (Thorsten Leemhuis)
Date: Fri Apr 21 2023 - 05:12:02 EST


Hi, Thorsten here, the Linux kernel's regression tracker.

I noticed a regression report in bugzilla.kernel.org. As many (most?)
kernel developers don't keep an eye on it, I decided to forward it by mail.

Bastien, from the bug report it to me sounds like it might be another
case caused by 908d325e166 ("HID: logitech-hidpp: Detect hi-res
scrolling support"), but I might be totally wrong with that (and the
reporter didn't even explicitly state that it's a regression, but it
sounds like one). If I got something wrong I apologize in advance.

Note, you have to use bugzilla to reach the reporter, as I sadly[1] can
not CCed them in mails like this.

Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=217353 :

See the ticket for more details.


[TLDR for the rest of this mail: I'm adding this report to the list of
tracked Linux kernel regressions; the text you find below is based on a
few templates paragraphs you might have encountered already in similar
form.]

BTW, let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:

#regzbot introduced: 908d325e1665
https://bugzilla.kernel.org/show_bug.cgi?id=217353
#regzbot title: hid: Logitech MX Anywhere 3 scroll wheel works
incorrectly over USB dongle
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply and tell me -- ideally
while also telling regzbot about it, as explained by the page listed in
the footer of this mail.

Developers: When fixing the issue, remember to add 'Link:' tags pointing
to the report (e.g. the buzgzilla ticket and maybe this mail as well, if
this thread sees some discussion). See page linked in footer for details.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
