Default Intel and USB-3: How are Nvidia and Microsoft involved?

Intel has been dragging it's feet over providing USB-3 support in it's
chipsets. This is because it really would rather see it's own "Light
Peak" fiber-optic solution become an industry standard instead.

Nvidia has been making a lot of noise over the fact that Intel has been
delaying USB3, but I'm not sure why Nvidia has a stake in this or why
Intel's delays affect Nvidia.

Then there is Microsoft, who did not give Windows Seven any native USB-3
drivers - not even in the recently released SP1.

I haven't seen these issues talked about here.

If you'll notice the article about Nvidia complaining, it's dated 2009,
when they still had a chipset business. It's 2010, and Nvidia has since
then dropped out of the chipset business, since Intel and Nvidia are
locked in a cross-licensing lawsuit, and Nvidia can't build chipsets for
Intel's newest processors.

Then there is Microsoft, who did not give Windows Seven any native USB-3
drivers - not even in the recently released SP1.


I think the USB3 support has to come from the chipset manufacturers
since it is really a PCIe-to-USB3 bridge that needs to be implemented.
Once that's provided, the rest of the stuff that gets attached to that
bridge will go through standard Microsoft drivers.

Light-Peak is a science project/marketing scheme from Intel, USB3 will
still be needed if Light-Peak is implemented as it won't be using the
same connectors as USB. Light-Peak might still be able to use existing
USB software drivers, but the hardware is completely incompatible.

NEC, the only one making USB3 chipsets ATM, provides the driver. Its pretty
lightweight so its no big deal.

That's how I see it too.
