# VZUSBPassthroughDevice

```
class VZUSBPassthroughDevice
```

## Overview\abstract Class representing a USB passthrough device.
\discussion This device is created through either instantiating it directly and passing
VZUSBPassthroughDeviceConfiguration to its initializer or instantiating a
VZUSBPassthroughDeviceConfiguration in a VZVirtualMachineConfiguration. Direct
instantiation will create an object that can be passed to -[VZUSBController
attachDevice:completionHandler:] method. Instantiation via
VZUSBPassthroughDeviceConfiguration will make the device available in the
usbDevices property of VZUSBController.
