Turns out I needed to enable USB2:

    <controller type='usb' index='0' model='ich9-ehci1'>
      <alias name='usb0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x7' multifunction='on'/>
    </controller>
    <controller type='usb' index='0' model='ich9-uhci1'>
      <alias name='usb0'/>
      <master startport='0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0' multifunction='on'/>
    </controller>
    <controller type='usb' index='0' model='ich9-uhci2'>
      <alias name='usb0'/>
      <master startport='2'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x1' multifunction='on'/>
    </controller>
    <controller type='usb' index='0' model='ich9-uhci3'>
      <alias name='usb0'/>
      <master startport='4'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x2' multifunction='on'/>
    </controller>

And add some redirection ports

    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir0'/>
      <address type='usb' bus='0' port='3'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir1'/>
      <address type='usb' bus='0' port='4'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir2'/>
      <address type='usb' bus='0' port='5'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir3'/>
      <address type='usb' bus='0' port='6'/>
    </redirdev>

With this done, I successfully (but accidentally) redirected my local
keyboard device to the guest.

I guess we need to produce some better text descriptions of each
device. 'lsusb' seems to be giving me better descriptions than
the ones virt-viewer does, so the info must be there somewhere.

Regardless, I have pushed these two patches
