Trying to use pvUSB in a Xen guest with a qemu emulated USB controller will crash qemu as it tries to attach a pvUSB device to the emulated controller.
This can be avoided by adding a unique id to each pvUSB controller which can be used when attaching the pvUSB device. In order to make this possible the pvUSB controller has to be a hotpluggable qemu device.
