Toby,
Thanks for taking the time to research and post this!
NEC/Renesas µD720200: The oldest (and thus most common) chipset. Doesn't meet 1.0 spec. Has a slightly odd implementation according to this review. Reports of it not working properly on Oneiric.
This is the one I've had problems with. Avoid.
One that I couldn't see on your list (unless it was under a different name) was:
USB controller: VIA Technologies, Inc. Device 3432 (rev 02) 02:00.0 0c03: 1106:3432 (rev 02)
Which has been working flawlessly for me under a variety of 3.2 kernels.
That's good to know -- I don't suppose you can find out what the chipset is actually called? It might be in your kernel messages somewhere. "Device 3432" in lspci just means the id isn't in the PCI ids table, but the xhci driver must have known more about it.
