I wonder if this if this is some related to this issue:
https://bugzilla.kernel.org/show_bug.cgi?id=217412
("Since kernel 6.3.1 logitech unify receiver not working properly")

That one so far seems to be ignored by the developers. Your report one
also didn't get any reply yet.

Could you maybe perform a bisection to get down to this?

Side note: there is also
https://bugzilla.kernel.org/show_bug.cgi?id=217330
("Broken Logitech unifying battery names in hid-next tree")


Anyway, for the rest of this mail:

[TLDR: 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.
See link in footer if these mails annoy you.]

Thanks for the report. To be sure the issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression
tracking bot:

#regzbot ^introduced v6.2..v6.3
#regzbot title input: Logitech Trackball M575 misidentified
#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 (the parent of this mail). See page linked in footer for
details.

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