I understand your own frustrations with Renesas, but it doesn’t help mine, much–many devices claiming to support “USB 3.0” support at best XHCI 0.95, I’m finding: not at all the same thing.
Unfortunately, Windows 8 doesn’t help for several reasons:
I use these products under Linux, too. I can’t keep yanking PCIe cards out of Linux machines just to update them under Windows–and Windows 8 has nothing to do with the constant firmware upgrade march on these controllers.
I won’t be using Windows 8.
If it did help, it looks like it’s 16 mos. out or more.
If it were only two mos. out, that still wouldn’t be today.
To misquote Yogi Berra, it’s like USB 2.0 all over again. (I clearly remember the massive headaches getting properly updated NEC USB 2.0 drivers installed and maintained under Windows 2000. At least no one that I recall released USB 2.0 devices that weren’t, actually.)
I’d be looking forward to Light Peak if: 1) I thought it would solve any of these problems; 2) it were compatible with USB 3.0 in any way; 3) I could expect to buy cables for (a lot!) less than USD$50; 4) Intel hadn’t already jerked us all around by speccing USB 3.0, then abandoning it, then picking it up again (Ivy Bridge chipsets, 2012).
