USB3.0 Function:
1. To provide 10 times the transmission speed of USB2.0， the maximum transmission rate of up to 5Gbps， in order to make a single USB3.0 interface can be exclusive and full-bandwidth PCI-Express ensure USB3.0 transfer rate， use a single USB3.0 interface USB3.0 connection device.
2. The need to provide more power， automatically reducing power consumption when not required， USB 3.0 can provide more power to support those who need more power-driven device， the USB device can be charged more quickly complete the charge. USB 3.0 support standby， hibernate and pause state.
3. downward compatible with version 2.0， USB3.0 using a 9-pin design， in which four pins and USB2.0 shape definitions are identical， while the other five are specially prepared for the USB3.0. USB2.0 devices can be perfectly used on USB3.0 interface.
