Came up with a workaround!

$ lsusb | grep -i silico
Bus 002 Device 006: ID 090c:1000 Silicon Motion, Inc. - Taiwan (formerly 
Feiya Technology Corp.) Flash Drive

# virt-xml KVM-USB-EUFI  --add-device --hostdev 002.006
Domain 'KVM-USB-EUFI' defined successfully.


XML file now looks like:

    <hostdev mode='subsystem' type='usb' managed='yes'>
      <source>
        <vendor id='0x090c'/>
        <product id='0x1000'/>
      </source>
      <boot order='1'/>
      <address type='usb' bus='0' port='4'/>
    </hostdev>
