USB Settings

A virtual machine can emulate only one USB controller, which provides you with the possibility to connect up to eight USB 2.0 and eight USB 1.1 devices to the virtual machine.

In the USB Controller pane, you can see the USB devices currently connected to your virtual machine.

If you want to prevent Virtual Machine Configuration from further unauthorized changes, click the Lock icon at the bottom of the window. The next time someone wants to change the settings on any pane of Virtual Machine Configuration, an administrator's password will be required.
