9. Support Six USB2.0 Connectors
Compared to traditional USB 1.0/1.1 with the speed of 12Mbps, USB 2.0 has a fancy
speed up to 480Mbps, which is 40 times faster than the traditional one. Except for the
speed increase, USB 2.0 supports old USB 1.0/1.1 software and peripherals, offering
impressive and even better compatibility to customers. On this motherboard, all USB
connectors support USB 2.0 function. To connect those two headers, you have to use
proper USB cables and connect them to any USB models.
