F_USB1~3: Front Panel USB 2.0 headers
The motherboard has six USB 2.0 ports installed on the rear edge I/O port array.
Additionally, some computer cases have USB 2.0 ports at the front of the case. If you
have this kind of case, use auxiliary USB 2.0 connector to connect the front-
mounted ports to the motherboard.
Unlike F_USB2~3 in this mainboard, F_USB1 supports EZ Charger technology,
provides 3 times 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.
