I have been using a Logitech wireless G602 mouse since forever. As of 
kernel 5.10.11 I get the following kernel messages;

Every mouse event seems to produce another "Unexpected input report 
number 128" kernel message.

The commit that started this is:

     [ Upstream commit e400071a805d6229223a98899e9da8c6233704a1 ]

     Tested. The device gets correctly exported to userspace and I can see
     mouse and keyboard events.
