Events

DeviceAccessDenied

This event is triggered when a connected device is inaccessible, e.g., when it is claimed by another process or when permission is denied.

public event EventHandler<DeviceAccessDeniedEventArgs>? DeviceAccessDenied

Event Type

EventHandler<DeviceAccessDeniedEventArgs>

DeviceConnected

This event is triggered when a device is connected. It will also trigger for all currently connected devices when device discovery starts.

public event EventHandler<DeviceConnectionChangeEventArgs>? DeviceConnected

Event Type

EventHandler<DeviceConnectionChangeEventArgs>

DeviceDisconnected

This event is triggered when a device is disconnected. It will only occur for devices that have previously triggered the DeviceConnected event.

public event EventHandler<DeviceConnectionChangeEventArgs>? DeviceDisconnected

Event Type
