Unlike F_USB2 in this mainboard, F_USB1 supports EZ Charger technology, pro-
vides 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.
