DA60 Known Issue: Power Save Functions on PC Don't Activate

The power save function on my PC is not activating while my DA60 is plugged in. How can I fix this?
When the DA60 is connected to a PC running Windows Vista, Windows 7, or Windows 8, power save functions (screen saver, sleep, hibernate, etc.) do not activate. 

The reason for this is that the DA60 is designed to send small data packets to the host and the data is intended to be received and processed by Persono Pro 2 program. Windows  XP and earlier Microsoft operating systems ignored this traffic. Starting with Vista and continuing through Windows 7 and 8, the OS considers this data stream as ‘user data’ input, like wiggling a mouse.  The result of this data stream is that the screen saver and power save functions never kick in.  After considerable investigation we have not identified a workaround to tell the OS that our device is not a mouse and to not consider the data stream as user input.
Note: The DA40 and DA45 do not exhibit this issue.
