Today I purchased a set of usb connected rear view mood lighting which are fantastic however I had hoped after turning the TV off by the remote the lights would also switch off but they don't so this means the USB ports are still powered on.

Is there a way to control the USB inputs so they power off and on at the same time as the TV as I can't see any control over them in the external inputs section.

 UPDATE: so I switched the TV off and sat and waited after 22mins the rear lights went out 5seconds later they were back on again with the TV still turned off after another 5mins the lights went out again however they stayed off for over 2 minutes then came back on again, the lights have turned off once again and have remained off now for 5mins and are still off at the time of writing why is the USB inputs behaving this way?

My TV is a bravia 49x8309c with the latest update installed.
