Yes, it works perfectly, even without a reboot since trying to use it
with pvusb

On the Intel machine that I'm testing with now, I do this to use it with
pvusb:

# Set some variables
device_id="1-4:1.0"
bus_id=`echo $device_id | sed 's/:.*//'`
domid=`xm domid $1`

# unlink all devices from any currently bound vports
cat /sys/bus/usb/drivers/usbback/vports | while read port
do
  echo "$port" >/sys/bus/usb/drivers/usbback/remove_vport
done

# set vport
echo "$bus_id:$domid:0:1" >/sys/bus/usb/drivers/usbback/new_vport

# call provided init script
~/usb_init_xs.sh $domid 0

# wait for a bit
echo waiting
sleep 5

# unbind device from whatever it is currently bound to (usb-storage in
this case) then wait a bit more
echo unbind
echo -n "$device_id" >/sys/bus/usb/devices/$device_id/driver/unbind
sleep 5

# bind the device to usbback
echo bind
echo -n "$device_id" >/sys/bus/usb/drivers/usbback/bind



after that, I unbound the device from usbback and re-bound it to
usb-storage and mounted the filesystem.

Have you been able to test with 3.4.1 or 3.4-testing yet?

Thanks

James
