USB HUB2.0 SL2.2S

This is a USB2.0 HUB2.0 controller integrated circuit that has been printed and verified. There are no problems yet. USB 2.0 HIGH SPEED 4-PORT HUB CONTROLLER
 
chip: SL2.2S
plug and play, no driver required.
 
Determine whether it can work normally: Wiring → Open Computer Management → Device Manager → Universal Serial Bus Controller (a USB 2.0 hub means success!!!) As shown in the picture,
 
this is a very simple circuit, you can design and draw it at will. (Unfortunately, I got tricked!!!)
 
VT1.0: There was an error in the components, which caused the USB socket to be soldered to the bottom (to be used).
This error has now been fixed! ! !
 
Component selection reminder:
A friendly reminder to those who have come here, when selecting, please choose those with high sales volume and those in stock, and do not choose unpopular components.
For example, I am an example, the USB interface is reversed... (vomiting blood!!!)
I will not make a bill of materials for this, I will clone and modify the USB socket and USB interface by myself! ! !
 
I hope this little work of mine can be helpful! ! !
