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.
Claims19
A method performed by an electronic device having a modified Universal Serial Bus (USB) Series A receptacle connector, the method comprising:
- detecting, by the electronic device, insertion of a standard USB Series A plug connector into the modified USB Series A receptacle connector;
- and
- in response to the detecting, determining, by the electronic device, whether to enter a host mode of operation or a peripheral mode of operation.
An electronic device comprising:
- a modified Universal Serial Bus (USB) Series A receptacle connector,
- wherein the electronic device is configured to detect insertion of a standard USB Series A plug connector into the modified USB Series A receptacle connector and, in response to the detecting, determine whether to enter a host mode of operation or a peripheral mode of operation.
An electronic device comprising:
- a Universal Serial Bus (USB) transceiver;
- a plug detect controller;
- and
- a modified USB Series A receptacle connector,
- wherein the plug detect controller is configured to:
- receive a signal from a plug detector disposed in the modified USB Series A receptacle connector indicating that a standard USB Series A plug connector has been inserted into the modified USB Series A receptacle connector;
- and
- in response to receiving the signal, determine whether to configured the USB transceiver as an upstream-facing transceiver or a downstream-facing transceiver.
