usb_add/del & pci_add/del are all deprecated and not going to be ported
to QMP. Instead use the device_add command eg in plain monitor format:

  device_add usb-host,hostbus=BUS,hostaddr=ADDR,vendorid=VID,productid=PRID

Or QMP format

    { "execute": "device_add", "arguments": { "driver": "usb-host",
                                              "hostbus": "BUS",
                                              "hostaddr": "ADDR",
                                              "vendorid": "VID",
                                              "productid": "PRID" }}

This accepts identical param names as the -device command line arg which is
documented in docs/qdev-device-use.txt
