Hi, Can somone please what the plug inside the hub is for?

Possibly a programming or debug port. Following the traces should give you an idea of what each of the pins are connected to. Then look up the data sheet(s) of the IC’s to see what the IO does that it is connected to.
I can connect my Glasgow to it and see what it detects. I have two spares since I’m using the hub now. I’m not sure when I’ll have the time to do it, though.
what do you have to do with it?
The plug you circled on the circuit board appears to be a connector, likely for a specific accessory or module.
Don’t think so, there’s no space for a cable to exit.
