Hi I have started looking at: https://bugzilla.redhat.com/show_bug.cgi?id=725670 My initial thought was to just add a new type of controller: <controller type='usb2' index='0'/> But it also needs the 3 companion UHCI controllers (see bug). We can either include them implicitely (not really elegant in libvirt, but doable), or with more flexibility list all the controllers in the XML: <controller type='ich9-usb-ehci1' index='0'/> <controller type='ich9-usb-uhci1' index='0' masterbus='0' firstport='0'> <controller type='ich9-usb-uhci2' index='0' masterbus='0' firstport='2'> <controller type='ich9-usb-uhci3' index='0' masterbus='0' firstport='4'> Any other idea? Daniel, have you also started working on USB2 & usb-redir support? regards -- Marc-André Lureau -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
