Ok, thanks for the detailed explanation, Marc.
So, preliminary tests on my F16 host and a winxp vm were successful
These were my steps:

- virsh edit winxp
Adding the usb line before the /devices line so that I had:

    <memballoon model='virtio'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x05'
function='0x0'/>
    </memballoon>
    <controller type='usb' index='0'/>
  </devices>
</domain>

- run virt-manager
I see now a "controller USB" between devices and can change model from
"default" to USB2 --> apply

- $ sudo diff new.xml old.xml
gives

49,62c49,50
<     <controller type='usb' index='0' model='ich9-ehci1'>
<       <address type='pci' domain='0x0000' bus='0x00' slot='0x08'
function='0x0'/>
<     </controller>
<     <controller type='usb' index='0' model='ich9-uhci1'>
<       <master startport='0'/>
<       <address type='pci' domain='0x0000' bus='0x00' slot='0x09'
function='0x0'/>
<     </controller>
<     <controller type='usb' index='0' model='ich9-uhci2'>
<       <master startport='2'/>
<       <address type='pci' domain='0x0000' bus='0x00' slot='0x0a'
function='0x0'/>
<     </controller>
<     <controller type='usb' index='0' model='ich9-uhci3'>
<       <master startport='4'/>
<       <address type='pci' domain='0x0000' bus='0x00' slot='0x0b'
function='0x0'/>

- Add hardware --> redirected USB --> spice channel
(BTW: what is the other option "TCP" for?)

Now the xml has got this added diff at its end:

<     <redirdev bus='usb' type='spicevmc'>
<     </redirdev>

NOTE:
A difference from when I manually edited the file (with Hans
instructions) is that this line now remains:
<domain type='kvm'>

while before it had to be manually changed to:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>

donna if this is important...

Tests:
- usb key
OK

- iTunes and iPOD shuffle last gen
OK
installed latest iTunes (10.5.3.3, 66Mb installer and about 350Mb
installation, worse than a virus... ;-)
and connected an ipod shuffle last generation
it was recognized both by the system and iTunes; I was able to
register it an play in iTunes some songs previously stored on the ipod
(with gtkpod... ;-)

So for now it is quite good result.

Tomorrow I'm going to test other devices on this system and another
F16 host with a win7 32bit guest (where I apparently had problems, as
detailed in this thread itslef previous e-mails):
- a Galaxy S2 with Kies
- a pair of cameras
- smartcard (for public health access)

and let you know.

Thansk in the mean time tor your time and sharing
