There are loads of issue reports that complain about this with Logitech hardware.

^ This thread _claims_ a fix was put in but it has not been (running 5.13 kernel)

I have reported recently in the libratbag tool similar.

We should probably document a "mitigation/workaround" to this. Simply using the mouse spams the logs hard.

I tried adding
/etc/rsyslog.d/50-default.conf

:msg, contains, "Unexpected input report number" stop

but it doesn't work :(

[fermulator (fermulator)]

For now

sudo modprobe -r hid_logitech_dj

and
/etc/modprobe.d/blacklist.conf

# Logitech HID driver sucks for G602
# https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1936573/
# https://github.com/libratbag/libratbag/issues/832
blacklist hid_logitech_dj
