Front USB Connectors: JUSB1 / JUSB2 / JUSB3

The mainboard provides three standard USB 2.0 pin headers JUSB1 & JUSB2

&JUSB3. USB 2.0 technology increases data transfer rate up to a maximum throughput of 480Mbps, which is 40 times faster than USB 1.1, and is ideal for connecting high- speed USB interface peripherals such as USB HDD, digital cameras, MP3 players, printers, modems and the like.
