# VZUSBController

A class that represents a USB controller in a VM.

## Declaration

```swift
class VZUSBController
```

## Overview

Overview Don’t create a VZUSBController directly. You need to first configure USB controllers on a VZVirtualMachineConfiguration through a subclass of VZUSBControllerConfiguration. When you create a VZVirtualMachine from the configuration, the USB controllers are available through the usbControllers property. The concrete type of a VZUSBController corresponds to the type the configuration uses. For example, a VZXHCIControllerConfiguration leads to a device of type VZXHCIController.
