The upcoming Windows 8 OS will fully support USB 3.0 and still retain backwards compatibility with the 10 billion existing USB 1.0 and 2.0 devices still in use. USB 3.0 will offer a 10x speed increase over USB 2.0 (up to 5 Gbit/s). USB 3.0 will provide 80% more power than USB 2.0 and allow for faster charging and remove the need for those “Y" cables used by external drives and other high power devices.
As of now there are no chipsets with USB 3.0 controllers onboard and the manufacturer of the motherboard has to use a third party chipset to enable USB 3.0 support. By 2015 all PCs sold will come with USB 3.0 ports, and there will be over 2 billion USB 3.0 devices sold that year as well. Microsoft is promising that Windows 8 will have robust USB 3.0 support.
Other work done to prepare for USB 3.0 included extensive hardware testing and creating a custom tool called MUTT (USB Test Tool) which can test 1000 USB devices for various compatibility issues.
