Method Description
RegisterForUsbEvents ( IntPtr hWnd, System.Guid gClass ) : IntPtr

Registers a window to receive windows messages when a device is inserted/removed. Need to call this from a form when its handle has been created, not in the form constructor. Use form's OnHandleCreated override.
UnregisterForUsbEvents ( IntPtr hHandle ) : bool

Unregisters notifications. Can be used in form dispose

RegisterForUsbEvents() public static method

Registers a window to receive windows messages when a device is inserted/removed. Need to call this from a form when its handle has been created, not in the form constructor. Use form's OnHandleCreated override.
public static RegisterForUsbEvents ( IntPtr hWnd, System.Guid gClass ) : IntPtr
hWnd System.IntPtr Handle to window that will receive messages
gClass System.Guid Class of devices to get messages for
return System.IntPtr

UnregisterForUsbEvents() public static method

Unregisters notifications. Can be used in form dispose
public static UnregisterForUsbEvents ( IntPtr hHandle ) : bool
hHandle System.IntPtr Handle returned from RegisterForUSBEvents
return bool
