Abstract
Apparatus and methods for disabling a USB or other interface connection between a personal computer and a docking cradle or device until the instant such a connection is actually needed. When the docking cradle is empty, the exposed pins are connected to a conductive ground path or is isolated. When a device is inserted into the docking cradle, the electrical signals that are connected to the personal computer by way of the interface are then switched on.
