K3s USB Codec unplugging itself

Joe, KO8V

I occasionally hear my windows system play the USB disconnect/connect sound when nothing has been plugged in or removed.  Using USBDeview, I found it seems the K3s Audio Codec disconnecting and reconnecting at some random times.  I know the codec is powered and visible to the computer when the radio is off.  I was wondering if there was something in the K3s that will recycle the codec on a random basis or for some other reason. It even happens in the middle of the night when I'm asleep.
