Systems and methods for power management on a transportation vehicle

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.

2. The method of claim 1 , wherein the listening threshold value is a first current value.

3. The method of claim 2 , wherein the operating threshold value is a second current value that is greater than the listening threshold value.

4. The method of claim 1 , wherein the operating power is greater than the initial power.

5. The method of claim 1 , further comprising: monitoring a current drawn by the USB device, while the USB device is in use; and detecting a drop in the current drawn value below a threshold to determine that the USB device is detached.

6. The method of claim 1 , wherein the transportation vehicle is an aircraft.

7. The method of claim 1 , wherein the transportation vehicle is not an aircraft.

8. A non-transitory machine-readable storage medium having stored thereon instructions for performing a method, comprising machine executable code which, when executed by a machine, causes the machine to:

configure a listening threshold value for a Type A, universal serial bus (USB) port on a transportation vehicle;

provide an initial power to the USB port without any attached USB device;

in response to attaching a USB device to the USB port, detect an increase in current at the USB port greater than the listening threshold value;

temporarily turn off the initial power to the USB port in response to detecting the increase in current greater than the listening threshold value;

set 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 disconnected from the USB port; and

reset the listening threshold value and providing the initial power to the USB port in response to detecting the drop.

9. The non-transitory machine-readable storage medium of claim 8 , wherein the listening threshold value is a first current value.

10. The non-transitory machine-readable storage medium of claim 8 , wherein the operating threshold value is a second current value that is greater than the listening threshold value.

11. The non-transitory machine-readable storage medium of claim 8 , wherein the operating power is greater than the initial power.

12. The non-transitory machine-readable storage medium of claim 8 , wherein the machine executable code which when executed by the at least one machine, further causes the at least one machine to: monitor a current drawn by the USB device, while the USB device is in use; and detect a drop in the current drawn value below a threshold to determine that the USB device is detached.

13. The non-transitory machine-readable storage medium of claim 8 , wherein the transportation vehicle is an aircraft.

14. The non-transitory machine-readable storage medium of claim 8 , wherein the transportation vehicle is not an aircraft.

15. A system, comprising:

a memory containing non-transitory machine readable storage medium comprising machine executable code having stored thereon instructions; and

a processor of a first node coupled to the memory, the processor configured to execute the machine executable code to: configure a listening threshold value for a Type A, universal serial bus (USB) port on a transportation vehicle;

provide an initial power to the USB port without any attached USB device;

in response to attaching a USB device to the USB port, detect an increase in current at the USB port greater than the listening threshold value;

temporarily turn off the initial power to the USB port in response to detecting the increase in current greater than the listening threshold value;

set 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

reset the listening threshold value and providing the initial power to the USB port in response to detecting the drop.

16. The system of claim 15 , wherein the listening threshold value is a first current value.

17. The system of claim 15 , wherein the operating threshold value is a second current value that is greater than the listening threshold value.

18. The system of claim 15 , wherein the operating power is greater than the initial power.

19. The system of claim 15 , wherein the machine executable code further causes to:

monitor a current drawn by the USB device, while the USB device is in use; and

detect a drop in the current drawn value below a threshold to determine that the USB device is detached.

20. The system of claim 15 , wherein the transportation vehicle is an aircraft.
