VIA Labs, Inc., a leading supplier of USB 3.0 integrated chip controllers, today announced two next generation USB 3.0 Host controllers, the four-port VIA VL805 and the two-port VIA VL806. The VIA VL805 and VIA VL806 allow a PCI Express-equipped platform to interface with multiple SuperSpeed USB peripherals devices simultaneously for blistering fast transfers rates up to 5 Gbps while retaining full backwards compatibility with USB 2.0 and 1.1 devices.

The next generation single chip VIA VL805 and VIA VL806 Host controllers include enhancements for improved performance, seamless cross compatibility and interoperability, and new features such as support for USB Battery Charging and "Charging Downstream Port" which enables both fast data sync and rapid charging with compatible devices. The VIA VL805 and VIA VL806 comply with the Universal Serial Bus 3.0 Specification for Super-Speed transfers and Intel's eXtensible Host Controller Interface (xHCI) 1.0 specification and add native inbox driver support for Windows 8. VIA VL805 and VL806 host controllers are USB-IF certified and are currently shipping.

"The VIA VL805 host controller is a feature-rich product that offers many tangible enhancements over previous generation devices including higher throughput, charging capabilities, and support for USB Debug Port" said Terrance Shih, Product Manager, VIA Labs, Inc. "With the smallest package design and native support in Windows 8, the VL805 and VL806 provide easy and cost effective ways for motherboard and embedded system manufacturers to bring additional USB 3.0 to their product lines."

Nice to finally see add-on cards that require external power, using SATA instead of Molex connectors.

Not buying into this for one minute...

VIA-LABS previous chipsets for PCI-E (VL800,VL801) don't work worth a darn. The several problems might be solved with a firmware update. But the firmware update utilities on the VIA-LABS support site are totally brain damaged and don't work. The Release Notes insist that the firmware must be updated BEFORE updating the drivers. So any drop-in board made with the previous chipset is a DEAD END PRODUCT. I know this to be true because I have bought four so far and none work.

So why should I ever buy anything with a VLI chip set?

As far as I am concerned anyone who buys product from that company is a fool and deserves to lose their money.
