[libvirt] [PATCH 27/34] Convert USB hostdevices over to -device

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

The old syntax was

   -usbdevice host:PRODUCT:VENDOR

Or

   -usbdevice host:BUS.DEV

The new syntax is

   -device usb-host,product=PRODUCT,vendor=VENDOR

Or

   -device usb-host,hostbus=BUS,hostaddr=DEV
