Why does my TravelMate P214 show a lower USB version number?
The Acer TravelMate P214 laptop shows USB 3.1 in Windows device manger, but it is actually using USB 3.2 according to the USB Implementers Forum (USB-IF). The USB-IF is a group that sets the rules for USB technology. In their updated guidelines, USB 3.2 includes everything that was part of the older USB 3.x versions (like USB 3.1). For the official details, you can check the guidelines on the usb.org website.
