1. An electronic device comprising:

  • a port engageable with a flat connector in any of plural orientations of the flat connector, the port comprising a power contact and data contacts, the power contact to engage a respective contact of the flat connector when the port and the flat connector are engaged; and

    a switching circuit comprising switches to;

    receive input signals from the data contacts of the port when the port is engaged with the flat connector, wherein the switches are controllable by an input power signal from the power contact of the port when the port and the flat connector are engaged, andapply polarity processing to the input signals to produce output data signals at a target polarity regardless of the orientation of the flat connector when engaged to the port, wherein the polarity processing is based on detecting a state of the power contact of the port.
