Version: Mouse wheel behaviour is broken after resume
Severity: normal

Dear Maintainer,

I've remarked that on a specific laptop the mouse wheel function is not
restored after resume. This is a regression that has been introduced between
Buster and Bullseye, and only occurs on one of my hosts.

Laptop model : Dell Latitude e6540
Mouse model : Microsoft Intellimouse 4500
Desktop environment : KDE

Steps to reproduce :
DO : boot the computer and open KDE
DO : open whatever application with a scrollbar and use the mouse scroll wheel
EXPECT : the scrolling works.
DO : suspend the computer to RAM for 5 minutes
DO : resume your activity
DO : open whatever application with a scrollbar and use the mouse scroll wheel
EXPECT : the scrolling works.
ACTUAL : the scrolling does not work.

Workaround : unplug and plug the mouse, or use a tool like resetmsmice (it
would be great to include it in the archive :
https://github.com/paulrichards321/resetmsmice )
