USB 3.0 Hub Controller Enters Second Generation

The VL811 4-port SuperSpeed Hub Controller is the company’s second-generation USB 3.0 Hub product. It adds support for USB Battery Charging Spec. 1.2 and delivers transfer rates up to 5 Gb/s. The 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. VIA TECHNOLOGIES INC., Fremont, CA. (510) 683-3300.
