Abstract
Methods and systems are provided for a transportation vehicle. One method includes configuring a listening threshold value for a Type A, universal serial bus (USB) port on the 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 greater than the listening threshold value; temporarily turning off the initial power to the USB port; setting an operating threshold value, and providing operating power to the USB port; detecting a drop in current when the USB device is disconnected; and resetting the listening threshold value and providing the initial power to the USB port.
