VL805 (4-Port)/VL806 (2-Port)是一个USB 3.0主机控制器，使一个配备PCI Express的平台能够与USB Super-Speed (5 Gbps)、High-Speed (480 Mbps)、Full-Speed (12 Mbps)和Low-Speed (1.5 Mbps)设备进行接口。根hub由四个面向下游的端口组成，允许多个外围设备同时运行。
VL805/VL806符合通用串行总线3.0规范和英特尔的可扩展主机控制器接口(xHCI)，并完全向后兼容USB 2.0和1.1规范，确保传统USB设备的无缝连接。VL805/VL806具有PCI Express 2.0 x1接口，向后兼容PCI Express 1.0，非常适合PC主机和插件卡应用程序。
VL805 (4-Port)/VL806 (2-Port) is a USB 3.0 Host controller, which enables a PCI Express equipped platform to interface with USB Super-Speed (5 Gbps), High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) devices. The root hub consists of four downstream facing ports enabling the simultaneous operation of multiple peripheral devices.
The VIA Lab’s VL805/VL806 complies with the Universal Serial Bus 3.0 Specification and Intel's eXtensible Host Controller Interface (xHCI), and is fully backward compatible with USB 2.0 and 1.1 specifications, ensuring seamless connectivity of legacy USB devices. VL805/VL806 have a PCI Express 2.0 x1 interface backwards compatible with PCI Express 1.0 and is perfectly suited for both PC Host and Add-In Card applications.
