当我尝试在VirtualBox中使用它时，我的USB设备是什么？
Ubuntu主机，XP客人。
当我连接我想要的USB设备到虚拟机时，我得到：
无法将USB器件Microchip Technology Inc. PICDEM FS USB演示板（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：控制台界面：IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

为什么举行？ 拿着它的是什么？ 注意：其他自定义USB卡工作正常。 这个虽然很旧，但它可能是USB1 / 1.1 / 2问题吗？ 我在我的虚拟机中暂时禁用了USB 2.0 EHCI，但没有变化。

我有一个类似的问题与不同的USB设备，Garmin运动手表。
这是我的配置：
- 主机 ：Ubuntu 14.04上的VirtualBox 5.0.0 r101573，安装了Oracle VM VirtualBox扩展包
- 访客 ：Windows 7，安装了VirtualBox Guest Additions
无论我在VM设置中选择什么USB控制器，每当我启动VM时，我都会收到错误：
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， 它可能是一个臭名昭着的VirtualBox bug，它仍然处于开放状态 （确切地说，重新打开了缺陷）。 有关详细信息，请参阅VirtualBox Ticket＃5175 。 这与设备的当前状态有关，它在某种程度上处于Held状态（可以通过运行VBoxManage list usbhost命令来检查）。
