I'm afraid that this solution won't work for me as my board don't support vt-d 
:( 
I'm a bit dissapointed that I buy real server hardware (FSC PRIMERGY RX100 S5) 
but don't get the advantage of vt-d as other cheaper desktop computers have... 
I can't believe that I need to buy hardware for several thousand euros just to 
have possibilities users with 500€ computers have...

so... pushing the whole usb controller into a guest need vt-d as far as I 
know.
