SiS Throws in with AMD, nVidia, and VIA for USB 3.0

AMD and nVidia claim that Intel is holding back on the specifications for the open host controller for USB 3.0. Intel denies that it is withholding the specification and says that the reason it hasn't provided the specs to rival CPU and chipset makers is that they aren't done. nVidia and AMD maintain that Intel has working silicon for the host controller, and that means the specs are done. Intel posted a blog last week to try and clear the situation up a bit.

Today nVidia announced that SiS has also thrown in with it and AMD. Now AMD, nVidia, VIA and SiS are all working together on their own open host controller for USB 3.0. That means that every other chipset maker is aligned to make their own specifications, which would effectively leave Intel in the dark as the only chipset maker with an open host controller specification that might not be compatible. This could work in nVidia and its partner's favor, if they can get to market first with USB 3.0 products. If Intel beats them to market significantly its open host controller specification still could become the standard. nVidia says it has already staffed the project and is moving ahead with its open host controller specification.
