So we have to use the first USB (20, 21, 54, 55, 30 and 64) for a external USB 3.0 port,
typically base boards would put a USB 3.0 port and USB 3.0 hub down *IF THEY WANTED TO*.
if however the designers of base boards wanted to do a simpler lower-power lower-cost board that did not need USB3 or was not expecting to have high-speed peripherals etc. then you could ignore the 3.0 lines entirely and put a 0.5 watt power supply IC down.
and use the second USB (34 and 68) to connect internally (by a HUB USB IC) the WIFI, the BT, the USB IC audio...
yeahhh pretty much. or 3G modems and the like. keyboards. mice. anything where you can expect it to be low-ish speed.
Is that better?
yeah.
Thanks.
