For usbctrl-attach/detach, usb-attach/detach, libxl has API, like
libxl_device_usbctrl_add/remove, libxl_device_usb_add/remove. That's
could be used for libvirt usage. The user interface processing things
are always do-by-itslef for xl and libvirt, what's libvirt needs to do is
preparing the usbctrl/usb device structure and call libxl API to do the
work.
