It is a bit confusing how you worded this.  Are you saying that you have 
already installed 6.5 and fully updated it to 6.8?

You're probably not going to like my suggestion.  Try CentOS 7.2 on this 
board and see what it finds.

There comes a time in every EL release cycle where new hardware is no 
longer well-supported.  CentOS 5 is way past that, and CentOS 6, while 
not as far past it is still too old to install on some of the newest 
hardware.  Even CentOS 7 has issues with some of the newest hardware.

You have the double-whammy of UEFI and a newer chipset.  While CentOS 
6.8 can handily support USB3 on some hardware (been there, done that 
myself, with CentOS 6.5 if I recall on a Dell Latitude D830 with an 
ExpressCard XHCI (USB3) controller that worked great).

You can of course try the ELrepo kernel-lt or kernel-ml packages, which 
provide the LongTerm or MainLine kernels packaged for CentOS.
