# HIDVirtualDevice.Properties

The properties for a virtual HID device.

## Declaration

```swift
struct Properties
```

## Mentioned in

Creating virtual devices

## Overview

Overview A virtual device has many properties, required and optional, that determine or alter its functionality. Use this class to provide these properties during the creation of a virtual device. Uncommon properties that aren’t available can be specified in the extraProperties parameter of init(descriptor:vendorID:productID:transport:product:manufacturer:modelNumber:versionNumber:serialNumber:uniqueID:locationID:localizationCode:extraProperties:).

## Topics
