您可能想直接将USB设备与VM相连，或者使用virt-manager GUI（有一个图形界面来添加USB设备），或者添加看起来像这样的行

<hostdev mode='subsystem' type='usb' managed='yes'>
   <source startupPolicy='optional'>
     <vendor id='0x03f0'/>
     <product id='0x4217'/>
   </source>
 </hostdev>
 <!--- TIMBER !!! this depend upon your USB device and machine would fail
                  to start if you miss, use the GUI instead! --->

我读了这篇文章：https://askubuntu.com/questions/828823/virtual-machine-manager-error-did-not-find-usb-device
