Homemade Usb_Hub

Overview

A self-made USB hub, and also added a TF card reader
to realize 1 to 4 through SL2.1A, and GL823K to realize the card reader function

A switch is also added to control whether the card reader chip is powered on. When my laptop does not have a TF card inserted and the GL823K chip is powered on, it will start up very slowly and have some bugs, so a switch is added for control.
