VIA Labs launches USB 3.0 Hub Controller
VIA Lab has unveiled the VIA Labs VL811 4-port SuperSpeed Hub Controller. The VL811 is VIA Labs' second-generation USB 3.0 Hub product, and adds support for USB Battery Charging Spec. 1.2. Beyond transfer rates of up to 5Gbps, the VL811 features improved performance for new and existing devices with host controllers, and adds rapid-charging capabilities.
"VIA Labs VL811 builds on the success of the VL810, the world's first 4-port USB 3.0 Hub controller. It adds exciting new features, such as the rapid charging function and improved performance," said Terrance Shih, Project Manager, VIA Labs, Inc USB 3.0 Hubs.
The VIA Labs VL811 hub controller adds a feature called "Charging Downstream Port," CDP, as defined in the USB Battery Charging Specification. When a BCS-compatible device is attached, the device can charge over 3x faster than conventional hubs or hosts. CDP allows users to transfer data while simultaneously charging their device at the same rate as when charging from an AC adapter.
