Need to Unplug Mouse To Properly Initialize and Work
I constantly still find that Mac does not properly initialize the USB Mouse when my Mac Pro 2019 boots. The Bluetooth Mouse has no issue.
I'm fairly certain this is a MacOS initialization issue and not a USB hardware issue because whenever I use Bootcamp, the Mouse never had issues being recognized.
But booting back into MacOS, there is always a chance that the USB mouse is not responsive even if the LED lights are powered.
The only solution is to unplug the USB mouse and re-insert.
