CentOS - Jul 2011 - CentOS 6 xhci_hcd USB 3 Support

I'm struggling with the xhci_hcd driver trying to get a NEC Corporation 
uPD720200 USB 3.0 Host Controller working under CentOS 6 x86_64. I've 
documented my efforts in the forums:

If anyone has any experience with the xhci_hcd driver, please share.

Thanks,
Kirk Bocek
