[CentOS-virt] USB 3.0 in qemu-kvm-0.12

[Robert Nichols]

I suspect I know the answer here, but is qemu-kvm-0.12 simply incapable
of passing a USB 3.0 device to a guest? USB 2 devices work fine, but
USB 3 -- nothing.  USB 3.0 works fine in the host, of course.

Currently using qemu-kvm-0.12.1.2-2.479.el6_7.4.x86_64 in CentOS 6.7.

I'm guessing I have to upgrade to CentOS 7 to pass USB 3.0 devices
to the guest.  Hoping to avoid that just now.
