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?

Plugging Devices into a Hubs Downstream Ports
Why do we get error messages when plugging a device into one of the hubs downstream ports? For example, when we connect a USB keyboard that need 400 mA power , we see the following error message in Windows: "The hub does not have enough power available to operate the USB Composite device".
