# VZUSBMassStorageDevice

A class that represents a hot-pluggable USB mass storage device.

## Declaration

```swift
class VZUSBMassStorageDevice
```

## Overview

Overview Create this device either by instantiating it directly and passing VZUSBMassStorageDeviceConfiguration to its initializer, or instantiating a VZUSBMassStorageDeviceConfiguration in a VZVirtualMachineConfiguration. Direct instantiation creates an object that you can pass to attach(device:completionHandler:). Instantiation through VZUSBMassStorageDeviceConfiguration makes the device available in the usbDevices property.
