A quick search for "rhel usb 3 support kvm" leads to this article:
"USB 3.0 support enabled in KVM as Technology Preview."
also, reading the release notes of upstream might help:
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.
