F_USB1~2: Front Panel USB 2.0 headers
The motherboard has four USB ports installed on the rear edge I/O port array.
Additionally, some computer cases have USB ports at the front of the case. If you
have this kind of case, use auxiliary USB connector to connect the front-mounted
ports to the motherboard.
Unlike F_USB2 in this mainboard, F_USB1 supports EZ Charger technology (op-
tional), provides 1A current than general USB port in off mode for USB devices. It is
useful and excellent, especially for the iPhone, iPad and iPod touch devices that need
a large amount of current for faster recharging within less time.
