# usbDevices

The list of USB devices.

```
var usbDevices: [any VZUSBDeviceConfiguration] { get set }
```

## Discussion

This list represents a set of USB devices that a VM starts with. For each entry in the list, the system creates a corresponding runtime object in the [`usbDevices`](/documentation/Virtualization/VZUSBController/usbDevices) property.

The list is empty by default.
