问题

当我启动VirtualBox虚拟机时，我得到：

Failed to open a session for the virtual machine win7pro32bit.


Implementation of the USB 2.0 controller not found!


Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be


 started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack'


 or disable USB 2.0 support in the VM settings (VERR_NOT_FOUND).



Result Code: NS_ERROR_FAILURE (0x80004005)


Component: Console


Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

sudo apt-get purge virtualbox


sudo apt-get autoremove


sudo apt-get update


sudo apt-get install virtualbox
