Yeah, no xhci kernel module....

Once you've tasted the speed of USB3 you really don't want to go back..... It's as fast as native eSATA on most of my USB3-capable externals.  Over twice as fast as USB2 on them.

An alternative would be to use the ELrepo 'mainline' kernel, assuming it has the xhci and/or xhci_hcd modules; but you'd be on your own configuring udev and friends to use it.  If that were to work, I sure would be interested.
