3，编辑客户机xml文件并增加以下内容

[root@localhost ~]# virsh edit windows2008R2-oldweb-backup

    <hostdev mode='subsystem' type='usb' managed='yes'>
      <source>
        <vendor id='0x1058'/>   对应lsusb中的1058
        <product id='0x1078'/>    对应lsusb中的1078
        <address bus='2' device='17'/>    对应lsusb中的  bus 和device 数字
      </source>
      <address type='usb' bus='0' port='2'/>
    </hostdev>
