USB Layout for the curious...

Ken

I believe I saw this somewhere before but was unable to locate it in a search, so I figured I'd share in a thread. The USB3.0 OTG connector sits on it's own root hub (as it's the only USB3). The 2.0 layout is 3 USBs on a 4 port root hub with the 4th connected to a peripheral hub connecting 3 more USBs. The center top USB on the connector end of the board is the hubbed USB along with the 2 USBs provided by the JST header at the other end of the board. The 2 outer USBs and the center bottom USB are connected to the root hub.
