Intel released a draft specification for USB 3.0 or SuperSpeed USB. The Extensible Host Controller Interface or xHCI provides a standard method for USB 3.0 host controllers to communicate with the USB 34.0 software stacks.
Both AMD and Nvidia voiced complaints earlier in the year that Intel hasn’t released update information to make the new spec an open industry standard and an easy path for transition. Today’s release is Intel’s answer to that request.
Dell, Microsoft and NEC also support the release because the xHCI will expedite the industry transition to next-generation USB 3.0 technology.
One important factor in adopting SuperSpeed USB products is interoperability between multiple devices from different manufacturers. The xHCI draft specification revision 0.9 aims to make interoperability easier to implement, while also making it easier for developers to create software support for the market.
The next revision update is expected at the end of 2008 with revision number xHCI 0.95. So no SuperSpeed USB yet, but the big boys are working their way to it.
