This provides coverage for the scenario in which an attempt is
made to use a USB device together with the legacy USB controller.
Note that, while the test case passes, the configuration it
produces doesn't actually work:
$ qemu-system-x86_64 -M pc -usb -device usb-tablet,bus=usb.0
Bus 'usb.0' not found
This is because the bus created by the legacy USB controller is
automatically assigned ID "usb-bus.0", but libvirt doesn't take
this into consideration when assigning addresses to USB devices.
In other words, the legacy USB controller will only work as long
as no attempt is made to attach devices to it, which arguably
doesn't make for a very useful controller.
