Abstract
A modified Series A universal serial bus (USB) receptacle connector is equipped with the functionality to allow the electronic system in which it resides to be configured either as a host device or a peripheral device. The modified USB Series A receptacle connector, according to one embodiment of the invention may include a mechanism such as an additional pin or a mechanical switch to detect the presence of a standard USB Series A plug being inserted into it. Upon detection of a plug, an algorithm may allow the system to determine whether it is to act as a host device or a peripheral device and to determine which device supplies power.
