List active mouse drivers on macOS Big Sur

The USB or Bluetooth subsystem detects the mouse and the operating system then just handles the device interaction. There are no mouse drivers to list as they are built-in to the operating system. You can press option + menu > System Information, and the panel that appears, you select Bluetooth, or USB to see more detail about the connected devices.

With Big Sur, you cannot install traditional kernel drivers as once was possible for two reasons: 1) the operating system now resides on a code-signed, read-only partition, and 2) Apple has abandoned the old device driver format that was used for years in macOS as kernel extensions.

Apple Support is not current with the fact that for reason (1) above, third-party mouse drivers would be blocked from an installation on Big Sur.

For the last decade or so, I have only used Apple mice and one Logitech mouse that had it's own plug-n-play USB radio dongle that required no driver installation. Apple has its own AppleUSB*.kext and IOUSB*.kext support in /System/Library/Extensions in Big Sur.
