Trying to make usb-hub

[desasteur]

Hey everybody, I'm trying to learn IC and I'm not really good...
But I just made usb-hub (with led) that is connected to a laptop by usb c, and I wanted to know what I did wrong.
Thanks !

I wanted to know what I did wrong.

What are the problems you have? More detail, please.

What are the problems you have? More detail, please.

Of course, it's my first circuit and and I'm not sure it work well, I would like to know if I made something wrong, like badly use a pin of the gl850g, or no protection against current, bad optimisation of data transfer,...
It's to print a good, working pcb and learn of my mistakes

Hello,

I have made some remarks on your schematic, that are not clear:


I found the V33, it is COMING from the GL850 pin 24.
The label shows an incoming signal at the GL850.
Please correct ALL labels to have a correct schematic.

Hello,

The GL850G has input , output and bi-directional signals.

Hello, thank you very much for helping me, I tried to make a circuit as simplest as possible, so I removed reset pin (I didn't fund it was necessary in datasheet) and I used clear labels, do you think it's better like that ?
