KVM -将USB传递给具有virsh/XML的来宾失败，但来自virt管理器。

Question

运行kvm的debian 8.8杰西。我不能将usb从主机重定向到客人(尝试了debian jessie和windows 2012作为客人，同样的问题)

libvirt 1.2.9-9+de8u4

如果我从virt管理器GUI重定向usb驱动器，客人会看到USB。

如果我使用"virsh附加设备客户端“hostdev.xml尝试重定向。来宾看到设备(lsusb和windows dev管理器)，但是没有检测到块设备(lsblk没有看到设备)。

# cat hostdev.xml
<hostdev mode='subsystem' type='usb'>
  <source>
    <vendor id='0x1976'/>
    <product id='0x6025'/>
  </source>
</hostdev>

以下是来宾在工作时的日志(vir-manager方法)

syslog消息看起来与“mtp-探测”相同。但失败的案例以mtp-探针停止，OK案例随后出现在检测USB棒阻塞设备上。

在windows 2012下，操作系统看到了新的“大容量存储.”在USB部分的开发管理器中输入，但在“磁盘管理”中和WIndows资源管理器中都没有可见的磁盘。

我如何使"virsh附加设备..XML“工作？

我没有安装任何装置。
