windows下vbox运行ubuntu 设备->USB里显示没有连接USB设备

nonamenotitle 2018-01-24 07:58:13

插好了移动硬盘，以前可以使用，但是vbox更新了5.2.6以后装了扩展包就没有显示USB设备了
百度搜到的都是linux下vbox里跑其他系统的解决办法，
我这里是windows10 下 vbox跑ubuntu（14）
请问怎么解决谢谢。。。

有人回复吗我也不知道应该把这个问题发在哪

ubuntu下Virtualbox中如果能使用USB 1. 安装vbox-extpack 2.把自己加入到vboxusers组。也就是在终端中输入： sudo adduser 你的用户名 vboxusers 然后退出，重新登录一次。

这是一个扩展包，因为最新devirtualbox没有集成usb的功能，所以需要安装这个扩展包才能实现虚拟机使用usb，这个是用在linux上的扩展包。
