This motherboard provides six
USB
ports to connect USB devices such as mouse, keyboard, modem, printer, etc. There is one USB
connector on the board for you to connect two USB devices and four other ports on the back panel. You can use proper cables to connect
USB devices from PC99 back panel or connect the front USB connector to the front panel of chassis.
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 six ports support USB 2.0 function.
