I think you may be mistaken, friend. The USB 3.0 controller is part of the A17 Pro SoC. It was specifically called out during the keynote when discussing the A17 Pro. You can read about it here too: https://www.tomshardware.com/news/apple-a17-pro-3nm-iphone-15-pro
I think point number three is likely what Deckwise is getting at. Every distro is stable when you don’t update it. I generally measure the stability of a distro on the ability to blindly update without taking out something mission critical.
