[libvirt-users] USB Host Controllers

[Michael Hierweck]

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).

Thanks in advance

Michael
