1. A method of establishing a weak ground path, comprising:
disabling a first ground path for a shield pin of a cable connection interface, the first ground path including a first switch;
enabling a second ground path for the shield pin, the second ground path comprises a second switch, and the second ground path having a higher resistance than the first ground path;
determining a connection of a device to the cable connection interface with the second ground path; and
enabling the first ground path based on the connection of the device being determined.
