Beschreibung
Zusammenfassung:	The present invention provides an apparatus that includes a resistive control block (RCB) coupled to data lines of a universal serial bus (USB) connector charging port and is configured to change a level of resistance between the data lines. The apparatus further includes a sensing and adjustment block (SAB) that is configured to sense a predetermined level of overheating of the USB connector charging port and cause the RCB to increase the level of resistance resulting in the USB connector charging port to appear as a different type of port. In another embodiment, an apparatus includes a RCB and SAB. The RCB is coupled to an identification and ground lines of a USB connector and configured to change a level of resistance between them. The SAB is configured to sense a predetermine level of overheating of a USB connector and cause the RCB to decrease the level of resistance.
