1. A method, comprising:
configuring a listening threshold value for a Type A, universal serial bus (USB) port on a transportation vehicle;
providing an initial power to the USB port without any attached USB device;
in response to attaching a USB device to the USB port, detecting an increase in current at the USB port greater than the listening threshold value;
temporarily turning off the initial power to the USB port in response to detecting the increase in current greater than the listening threshold value;
setting an operating threshold value, and providing operating power to the USB port;
detecting a drop in current at the USB port below a disconnect threshold value when the USB device attached to the USB port becomes is disconnected from the USB port; and
resetting the listening threshold value and providing the initial power to the USB port in response to detecting the drop.
