Hi, it is possible to define a domain along with several usb host controllers, e.g. <controller type='usb' index='0' model='ich9-ehci' /> <controller type='usb' index='1' model='ich9-uhci' /> How to distinguish between those controllers/busses when adding input or host devices such as <input type='tablet' bus='usb'/> <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='...'/> <product id='...'/> </source> </hostdev> Without explicit assignment either every device seems to be attached to the uhci controller or the domain refuses to start because the tablet is attached to the ehci controller implicitly, depending on the order of the controller definition (index).
