我想连接一个 CAN 到 USB 接口，以便将发动机控制单元编程到 WinXP 虚拟机。但这个设备没有列在虚拟机窗口左下方的小 USB 图标下。
运行 usb-devices 我得到以下信息：
T: Bus=06 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=ff(vend.) Sub=ff Prot=00 MxPS=16 #Cfgs= 1
P: Vendor=0000 ProdID=0102 Rev=01.00
C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 4 Cls=00(>ifc ) Sub=00 Prot=00 Driver=(none)
我的 VM 可以与所有其他 USB 设备（包括一些不常见的设备）配合使用。在我的系统上无法使用的设备在 Mac 上的 VirtualBox 和大学笔记本电脑的 BSD 主机上可以正常工作。
我正在运行 Ubuntu 12.04 和 virtualbox 4.1.18
提前感谢，这确实会使我的工作变得容易很多，而不必一直启动 win :-(

答案1
这可能是 Ubuntu 中 VB usb 支持的问题
按照前面所述安装 USB 2.0 支持https://www.virtualbox.org/wiki/Downloads
但随后将您的用户添加到虚拟盒用户团体https://help.ubuntu.com/community/VirtualBox/USB
在 VB 中，vboxusers 没有 USB 权限是一个常见问题
sudo adduser yourusername vboxusers
遗憾的是，添加到组后，您需要注销并登录，然后重试，VB 应该识别列表中的 USB
（在最后的版本中甚至不需要添加过滤器，您只需在正在运行的虚拟机上打开“USB 设备”菜单并选择设备并将其插入客户端机器即可）
答案2
你必须安装virtualbox extension pack
https://www.virtualbox.org/wiki/Downloads
并且您还想安装guest additions以获取适合您的 VirtualBox 客户端的驱动程序。
答案3
某些 USB 设备可能无法与 Virtual Box 正常配合使用。您的 CAN 转 USB 接口可能存在这种情况，但如果我们让 Virtual Box 访问它，则值得尝试。
为此，我们可能会尝试添加“空的”机器的 USB 设置中的 USB 过滤器：
这可能已经有助于识别您的设备。我们也可以尝试在右键单击“新文件管理器 1”打开一个设置窗口，其中包含每个条目的一些解释性工具提示：
另请阅读Virtual Box 使用手册了解这些设置的解释以及如何获取它们。
答案4
您能否确认您已选中Enable USB 2.0 (EHCI) ControllerTakkat 回复中显示的复选标记？此外，当您将 USB 设备插入计算机时，查看其发生的情况可能很有用。考虑到这一点，以下命令可能有助于您开发更多信息
lsusb
udev monitor
您可能需要为设备创建 udev 规则，以确保它属于适当的组。了解更多有关您正在使用的设备的信息可能会有所帮助。
