I was using win7 32bit, and configured usb controller nec-xhci as well as usb tablet emulation. But it didn't work. Seems usb tablet failed to connect to xhci controller.
57 <controller type='usb' index='0' model='nec-xhci'/>
58 <input type='tablet' bus='usb'>
59 <address type='usb' bus='0' port='1'/>
60 </input>
