I finally got altium viewer installed and looked at the board designs. Removing J1 would remove all power to the USB. But you would need to power the tp-link by some other means
You are reading it wrong

F1 powers USB-A1, nothing is connected there. The tp-link is connected to USB-B1.
First time reading one of these things, I'm going blind! What a horribly tedious job designing this stuff must be.
At least it's an easy fix for anyone who's cloning the avalon design. Should just be able to delete the one pathway that leads back to the usb-hub from the usb-a1, no?
