W2k Driver for Nec's Usb 3.0?

[pointertovoid]

Hello nice people!

You may know (but are welcome to ignore) that NEC produces a chip (µPD720200 or UPD720200) that adds USB 3.0 ports on a PCI-E lane. As all (or nearly all?) chipsets up to now have only USB 2.0 ports, motherboards include this chip.

I haven't seen anywhere a Win2000 driver for this chip, neither at NEC nor at the motherboard manufacturers. Which is a pity, since W2k drivers exist (sometimes unofficial but excellent) for the chipsets of these motherboards.

So:

Does this driver exist? Official or not.

Or do we get the USB 3.0 speed without an extra driver?

Thanks!
