A Vagrantfile has been placed in this directory. You are now
ready to vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "7b5094ad-75e4-4e75-9100-794569c929c7", "--type", "headless"]

Stderr: VBoxManage: error: Implementation of the USB 2.0 controller not found!
VBoxManage: error: 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.
VBoxManage: error: Note! This error could also mean that an incompatible version of the 'Oracle VM VirtualBox Extension Pack' is installed (VERR_NOT_FOUND)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole
