Incorporating two Universal Host Controller Interface (UHCI) cores for full signaling and one Enhanced Host Controller Interface (EHCI) core for high-speed signaling, the VIA Vectro VT6212L is a multi-functional PCI device that utilizes the exceptional bandwidth of USB 2.0 to support a wide range of high-speed peripherals, including high resolution video, webcams, digital cameras, next-generation scanners and printers and high-density storage devices.
The VIA Vectro VT6212L root hub consists of four downstream facing ports with integrated physical layer transceiver and legacy support, enabling the simultaneous operation of multiple peripheral devices. The VIA Vectro VT6212L is fully backward compatible with the USB 1.1 specification, ensuring seamless connectivity of legacy USB devices.
