I want to make a USB Y connector from a PC USB backplate it is faster than buying one, fun and educational, (a usb hub is 20 dollars here).
I have many PC USB backplates available to wire into a hub so i had a go:
I wired all the wires of the same color together in Y formation, but i can only use one of the usb plugs at a time, and not both.
Is there a way to switch round some of the colors so that they are useable concurrently?
I thought USB was simply in series / in parallel.
