Abstract
One aspect includes a system, including: a portable device having a receptacle; and a cable assembly including a plug connectable to the receptacle; the cable assembly including: a first connection for a peripheral device; a second connection for a charger; and a control section that indicates a charging mode to the portable device permitting connection of both the charger and the peripheral device to the portable device. Other aspects are described and claimed.
Claims20
A system, comprising:
- a portable device having a receptacle;
- and
- a cable assembly including a plug connectable to the receptacle;
- the cable assembly including:
- a first connection for a peripheral device allowing data communication between the peripheral device and the portable device, wherein the first connection comprises an ID pin;
- a second connection for a charger allowing charging of the portable device from the charger, wherein the second connection comprises an ID pin;
- and
- a control section that indicates a charging mode to the portable device permitting connection of both the charger and the peripheral device to the portable device in any order without any voltage collisions on the cable assembly while allowing the data communication and the charging, wherein the connection in any order is permitted based upon a state of the ID pin of the first connection and a state of the ID pin of the second connection.

A cable assembly, comprising:
- a first connection for a peripheral device allowing data communication between the peripheral device and the portable device, wherein the first connection comprises an ID pin;
- a second connection for a charger allowing charging of the portable device from the charger, wherein the second connection comprises an ID pin;
- and
- a control section that indicates a charging mode to a portable device permitting connection of both the charger and the peripheral device to the portable device in any order without any voltage collisions on the cable assembly while allowing the data communication and the charging, wherein the connection in any order is permitted based upon a state of the ID pin of the first connection and a state of the ID pin of the second connection.
1 more element
A method, comprising:
- detecting, at a cable assembly, connection of a portable device;
- and
- indicating, using the cable assembly, a charging mode to the portable device permitting connection, to the portable device, of both a charger that charges the portable device and a peripheral device that communicates data to the portable device via the cable assembly in any order without any voltage collisions on the cable assembly while allowing the data communication and the charging, wherein the indicating comprises identifying a state of an ID pin of a first connector of the cable assembly for the charger and a state of an ID pin of a second connector of the cable assembly for the peripheral device.
