For HX2LP OVR# Pins, Whether They Have an Internal Pull-up Resistor or Need an External Pull-up - KBA82846
Question: The HX2LP datasheet states a default state of '1' for the OVR# pins. Do they have an internal pull-up resistor or do we need an external pull-up if the pins are not used?

Higher Power consumption of TetraHub when in unconnected powered state
I have the TetraHub evaluation powered up and am measuring the current drawn by the device in connected and unconnected state. When I measure the current drawn by TetraHub and not connected to any host, it seems to be a lot more than what is measured when it is in a connected state. Power consumption is approximately 3.1W when unconnected. When connected power consumption goes down to approximately 1.2W. Why is the power consumption of TetraHub in a connected state more than it is when in an unconnected state?
