SVP causes Logitech Unifying Receiver to become disabled.

After much troubleshooting I have discovered that SVP Manager somehow disables the Logitech Unifying Receiver and K400 keyboard.

Now here is the strange part. It actually works.

However when I have a headset plugged in the Logitech Receiver and the K400 Keyboard become disabled.
The moment I unplug them the Receiver and Keyboard work.

Now the Logitech K400 and Gaming Headset work the same time but the moment I load up a video or if a video is running /w SVP instantly the keyboard and receiver are disabled.

I have tested Platronics 780 Gaming Headset running video /w SVP causes the K400 "keyboard" to become disabled. The mousepad and right and left clicks on the keyboard still work.
I have tested Hyper X Cloud 2 Gaming Headset running Video /w SVP and both the keyboard and mousepad and right and left clicks are completely disabled.

I am unsure why SVP Manager would even cause this but it definitely is.

Any help would be much appreciated.

Thanks.
