Unlike F_USB2~4 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.
