mcf*_*son 5 virtualbox macosx usb-storage xhci-hcd
在过去的几天里，我花了大量时间寻找解决这一挑战的方法。
我有一个 Seagate Expansion Desktop Drive，它是一个用于测试的外部 2 TB USB 3.0 磁盘。在一次测试中，该驱动器连接到我的 Macbook Pro 上的 USB 3.0 端口，并连接到我的 Mac Mini 上的 USB 3.0 端口进行另一次测试。Macbook Pro 和 Mac Mini 都安装了 virtualbox 并安装了 Ubuntu 客户机。该驱动器应该可供 ubuntu 来宾访问。
我当前的设置：Macbook Pro：

前提条件：希捷硬盘连接到 Macbook Pro（或 Mini）上的电源和 USB 3.0 端口（在 osx 中的 Filer 中弹出） Macbook Pro 启动并登录 VirtualBox 启动 Guest (Ubuntu 14.04) 启动并登录（窗口模式不是全屏）
预期结果：希捷硬盘应列在 ubuntu 设备下的文件管理器中。该驱动器应在 /dev 中列为驱动器，例如 ubuntu 中的 /dev/sdb 该驱动器应可在 ubuntu 中安装
实际结果：该驱动器未列在 ubuntu 中设备下的文件管理器中 该驱动器未列在 ubuntu 中 /dev 下

我怀疑问题出在 dmesg 的这一行上：
[ 795.857795] usb 2-1: USB controller 0000:00:0c.0 does not support streams, which are required by the UAS driver.
是 Virtualbox 问题还是 Ubuntu 问题？ubuntu 无法正确处理 USB xHCI 控制器吗？
顺便说一下，驱动器在专用的 kubuntu 工作站上工作，在同一台 macbook pro 的 Windows 10 虚拟机上工作。
@nephente（按要求追加）我假设您的意思是将 VirtualBox 中的控制器设置为 USB 2.0 (EHCI) 控制器。如果是这种情况，那么我在 VirtualBox 中收到以下错误：
Failed to attach the USB device Seagate Expansion Desk [0100] to the virtual machine patal-vbox-ubuntu-002.
Failed to create a proxy device for the USB device.
(Error: VERR_PDM_NO_USB_PORTS).
Result Code: NS_ERROR_FAILURE (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
我也尝试过但没有提及的另一件事是将 USB 3.0 设备连接到 USB 2.0 集线器，然后将集线器连接到 Macbook Pro。这也不起作用。
@Takkat 感谢您建议创建过滤器并确保从 osx 卸载/弹出驱动器。
我为 Seagate Expansion Desk（台式机和台式机）创建了一个过滤器，并确保该驱动器未安装在 osx 中。
结果：确保未安装驱动器并为驱动器创建过滤器没有任何区别。该驱动器仍可识别，如本文开头所述。
