<p>USB3.0 function:</p> <p>1. The transmission speed of USB3.0, the high transmission rate can reach 5Gbps, in order to enable a single USB3.0 interface to exclusively enjoy the PCI-Express bandwidth and fully guarantee the USB3.0 transmission rate, please use a single USB3.0 interface to connect USB3.0 equipment.</p> <p>2. It can provide more power when needed, and automatically reduce power consumption when it is not needed. USB 3.0 can provide more power to support devices that need more power to drive, and devices that use USB to charge can complete charging faster. USB 3.0 supports states such as standby, hibernate and suspend.</p> <p>3. Backward compatible with version 2.0, USB3.0 adopts a 9-pin design, four of which have the same shape and definition as USB2.0, and the other five are specially prepared for USB3.0. USB2.0 devices can be used on the USB3.0 interface.</p> <p>Function description:</p> <p>Extend 4 USB3.0 ports on PC with PCI-Express slot</p> <p>Specifications:</p> <p>Support PCI Express2.0 bus specification</p> <p>PCI Express data transfer rate up to 5Gbps</p> <p>Compliant with USB3.0 interface specification</p> <p>Backward compatible with USB2.0\/1.1 specification</p> <p>USB3.0 interface data transfer rate up to 5Gbps, USB2.0 interface data transfer rate up to 480Mbps</p> <p>The USB3.0 interface can provide 900mA of current to power external devices</p> <p>Support plug and play</p> <p>System Requirements:</p> <p>A computer with an available PCI Express slot</p> <p>Supported operating system: Windows 2000, XP, Vista, WIN7 operating system</p> <p>Chip model: designed with VIA platform</p> <p>PCI-E USB3.0 2ports chipset: NEC 1, Compliant with PCI Express Base Specification, Revision 1.1</p> <p>2,SuperSpeed (5.0Gbps) additional</p> <p>3,USB 3.0 will offer a myriad of possibilities for applications requiring fast</p> <p>and high-capacity communication, while maintaining compatibility with USB 2.0.
