Hi Fernando,
in 3.6 to pass an host USB device to a VM you don't need an hook as it
is now standard in the system.

But if you have vdsm from 3.6.6 it doesn't work because of a bug. It
has already been corrected and if you update vdsm* to 3.6.7rc it will
work. I had the same problem but now it's OK.

Going to the administration portal after the upgrade you should see
your USB device in the "Host devices" tab of the "Host"; if it isn't
there clik "Refresh Capabilities" and it should come up.
Then you go to "Virtual Machines", select your VM, then "Host devices"
and "Add device" and you're almost there.

I learned this thanks to something posted in this list and probably a
bugzilla too but I'm unable to find it ATM.
If you see references to IOMMU ignore them unless you need to expose a
PCI device.

HTH,
Giorgio.
