The xHCI architect hasn't done an official release on the Intel site for
a while now.  I think he's working on a bigger 1.1 release that includes
all the errata over the past couple years.

I think you can get the latest revision by emailing
xhcisupport@...el.com.  If you don't hear back within a week or so,
email me back and I'll send you a PDF.

Yes, please fix this in VMware's virtual hardware.
