Ubuntu 主机，XP 客户机。
当我将我想要的 USB 设备连接到虚拟机时，我得到：
无法将 USB 设备 Microchip Technology Inc. PICDEM FS USB Demo Board (C) 2004 连接到虚拟机 DevelXP。无法为 USB 设备创建代理设备。（错误：VERR_READ_ERROR）。结果代码：NS_ERROR_FAILURE (0x80004005) 组件：控制台接口：IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

为什么会被阻止？是什么阻止了它？注意：其他自定义 USB 卡工作正常。不过这个卡比较旧，所以可能是 USB1/1.1/2 的问题？我在虚拟机中暂时禁用了 USB 2.0 EHCI，但没有变化。

$ sudo udevadm info -a -p /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

答案1
我在使用另一个 USB 设备（Garmin 运动手表）时也遇到了类似的问题。
这是我的配置：
- 主持人：Ubuntu 14.04 上的 VirtualBox 5.0.0 r101573，安装了 Oracle VM VirtualBox 扩展包
- 客人：Windows 7，安装了 VirtualBox Guest Additions
无论我在 VM 设置中选择哪个 USB 控制器，每当我启动 VM 时都会收到错误：
无法为 USB 设备创建代理设备。（错误：VERR_READ_ERROR）。
结果代码：NS_ERROR_FAILURE (0x80004005) 组件：ConsoleWrap 接口：IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
经过一些研究，我得出结论这很可能是一个臭名昭著的 VirtualBox 漏洞，目前仍处于开放状态（准确地说，是重新打开的缺陷）。请参见VirtualBox 票号 #5175了解详情。这与设备的当前状态有关，设备处于某种状态Held（可以通过运行命令进行检查，VBoxManage list usbhost正如您所做的那样）。
