Native support for USB 3.0 on Windows 8

The next operating system from Microsoft, Windows 8 will integrate native support for the standard USB 3.0 controllers will be automatically recognized and no longer require separate drivers as with current versions of Windows. The news comes from Dennis Flanagan, Director of Program Management for the Networking and Devices Group at Microsoft, and though truth is not so surprising given that now all the manufacturers of motherboards and chipsets have integrated (or are doing) some form of support to USB 3.0 in its components, explains how Microsoft has implemented this support in Windows 8.

Instead of adding the driver on the software stack of USB 1.1 and 2.0, Microsoft's engineers have chosen to write a completely new software stack for USB 3.0 separated leaving the old one. The decision to invest in a USB 3.0 was an easy one to make, but doing so without compromising the existing USB ecosystem was a big challenge to overcome.
