Configuring a Virtual Machine 217
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.
