My DVR box is overheating and displaying a message on the screen. I purchased a Laptop Computer cooling unit that fits under the box & has a fan in it. Problem solved.... partially. The fan plugs into the USB port on the cable box for power. I assumed the USB port would turn off with the box but no such luck. The fan runs 24x7. Is there a way to program the unit to turn off the USB port when powering off the cable box?
