The reason that I'm asking is, there seems to be a number of different USB3.0 controller chips, that each need their own unique driver. (Etron, Renasis/NEC, AMD, Intel, ASMedia, etc.) Back in the days of USB 1.1 and 2.0, there were standards for the controllers, (OHCI, EHCI, etc.), and a driver written to that standard, would work with any brand controller than was also mfg to that standard. Thus, allowing OS-level USB support in Windows, that was controller brand-agnostic. Now, I know that Windows 7 does not support USB 3.0 out of the box, and this causes issues for machines that ONLY have USB 3.0 ports, and no optical drive, to install Windows 7 on. Supposedly, Windows 8 supports USB 3.0 out of the box, but does that simply mean that it includes drivers for all of the prevalent brands of USB 3.0 controllers on the market today, but future USB 3.0 controller hardware might not be supported? This seems like a gaping hole that the USB 3.0 standards folks should have fixed.
