Why all this focus on a mouse?

In my limited experience...the mouse itself is more likely to fail and need to be replaced...than to assume that anything as nefarious as malware is at work.

If you take your system to a shop...they will plug in a shop mouse, keyboard, and monitor to access your system and attempt to troubleshoot system problems. I would say that all this focus on a mouse for anything other than a computer peripheral...is making a mountain out of a molehill.

Probably nothing to be concerned about.  But there is a slight risk in the firmware of any USB device.  "BadUSB" ... https://www.wired.com/2014/07/usb-security/


All manner of USB devices from keyboards and mice to smartphones have firmware that can be reprogrammed—in addition to USB memory sticks, Nohl and Lell say they’ve also tested their attack on an Android handset plugged into a PC. And once a BadUSB-infected device is connected to a computer, Nohl and Lell describe a grab bag of evil tricks it can play. It can, for example, replace software being installed with with a corrupted or backdoored version. It can even impersonate a USB keyboard to suddenly start typing commands. “It can do whatever you can do with a keyboard


ensuring that their USB's firmware hasn't been tampered with is nearly impossible. The devices don't have a restriction known as “code-signing,” a countermeasure that would make sure any new code added to the device has the unforgeable cryptographic signature of its manufacturer. There's not even any trusted USB firmware to compare the code against.
