I suspect I know the answer here, but is qemu-kvm-0.12 simply incapable

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.
A quick search for "rhel usb 3 support kvm" leads to this article:
http://www.tecmint.com/redhat-enterprise-linux-7-1-installation/
citing:
"USB 3.0 support enabled in KVM as Technology Preview."
also, reading the release notes of upstream might help:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html-single/7.2_Release_Notes/index.html
if you CTRL+F "usb 3" you can read:
USB 3.0 host adapter (xHCI) emulation for KVM guests remains a
Technology Preview in Red Hat Enterprise Linux 7.2.
so it is available but not fully supported.
Thanks for the info. I hadn't gotten to the point of looking into what
the support was/wasn't for USB 3 virtualization in RHEL 7. Looks like
I can delay my upgrade at least until RHEL 7.3 appears.
