The Universal-Serial-Bus interface includes an electrical connection structure to electrically connect the first electronic device and the second electronic device with one another and a switch to disconnect the electrical connection structure. A measurement circuit to measure one or more electrical properties is associated with the electrical connection structure and/or the first electronic device. One or more processors configured to control the switch based on the measured one or more electrical properties. ## Claims ### Claim 1 A security device comprising: a first set of terminals to connect the security device with a Universal-Serial-Bus connector, a second set of terminals to connect the security device with an electronic device, a controllable terminal connection structure to connect the first set of terminals and the second set of terminals with one another and to disconnect the first set of terminals and the second set of terminals from one another to control a physical connection of the Universal-Serial-Bus connector to the electronic device; a measurement circuit coupled to the first set of terminals to measure one or more electrical properties associated with the Universal-Serial-Bus connector when connected to the first set of terminals; and one or more processors configured to control the controllable terminal connection structure based on the determined one or more electrical properties. ### Claim 2 (depends on 1) The security device of claim 1, wherein the controllable terminal connection structure comprises a switch having a first switching state in which the first set of terminals and the second set of terminals are connected with one another and a second switching state in which the first set of terminals and the second set of terminals are disconnected from one another. ### Claim 3 (depends on 2) The security device of claim 2, wherein the one or more processors are configured to control the controllable terminal connection structure only by switching the switch from the first switching state into the second switching state. ### Claim 4 (depends on 2) The security device of claim 2, wherein the controllable terminal connection structure further comprises a mechanical mechanism for switching the switch from the second switching state into the first switching state. ### Claim 5 (depends on 4) The security device of claim 4, further comprising: a lockable mechanical protection structure configured to restrict a physical access to the mechanical mechanism. ### Claim 6 (depends on 1) The security device of claim 1, wherein the first set of terminals and the second set of terminals each comprise at least four terminals associated with at least four cores of a Universal-Serial-Bus cable and/or at least four Universal-Serial-Bus pins of the Universal-Serial-Bus connector. ### Claim 7 (depends on 6) The security device of claim 6, wherein the first set of terminals further comprises at least two additional terminals associated with at least two additional cores of the Universal-Serial-Bus cable and/or at least two additional pins of the Universal-Serial-Bus connector. ### Claim 8 (depends on 1) The security device of claim 1, wherein the one or more electrical properties includes an electrical resistance and/or an electrical impedance. ### Claim 9 (depends on 1) The security device of claim 1, further comprising: a power supply to supply the one or more processors and/or measurement circuit. ### Claim 10 An automated teller machine comprising: a safe unit; a security device comprising: a first set of terminals to connect the security device with a Universal-Serial-Bus connector, a second set of terminals to connect the security device with an electronic device, a controllable terminal connection structure to connect the first set of terminals and the second set of terminals with one another and to disconnect the first set of terminals and the second set of terminals from one another to control a physical connection of the Universal-Serial-Bus connector to the electronic device; a measurement circuit coupled to the first set of terminals to measure one or more electrical properties associated with the Universal-Serial-Bus connector when connected to the first set of terminals; and one or more processors configured to control the controllable terminal connection structure based on the determined one or more electrical properties, wherein the security device is disposed inside the safe unit; a Universal-Serial-Bus connector disposed outside the safe unit and connected to the first set of terminals of the security device; and an electronic device (114) disposed inside the safe unit (400s) and connected to the second set of terminals (104) of the security device (100). ### Claim 11 (depends on 10) The automated teller machine of claim 10, further comprising: an electromechanical device disposed inside the safe unit, wherein the electronic device is configured to control operation of the electromechanical device based on control data transmitted via the Universal-Serial-Bus connector. ### Claim 12 (depends on 10) The automated teller machine of claim 10, further comprising: a computing system disposed outside the safe unit, wherein the Universal-Serial-Bus connector is connected to the computing system or is part of the computing system. ### Claim 13 A method for operating an electronic device arrangement, the method comprising: communicatively coupling a first electronic device of the electronic device arrangement to a second electronic device of the electronic device arrangement via a Universal-Serial-Bus interface, wherein the Universal-Serial-Bus interface comprises an electrical connection structure to electrically connect the first electronic device and the second electronic device with one another and a switch to disconnect the electrical connection structure); measuring one or more electrical properties associated with the electrical connection structure and/or with the first electronic device; and triggering the switch to disconnect the electrical connection structure based on the measured one or more electrical properties. ### Claim 14 (depends on 13) The method of claim 13, further comprising: after triggering the switch, manually resetting the switch via a mechanical mechanism to electrically connect the first electronic device and the second electronic device with one another. ### Claim 15 (depends on 14) The method of claim 14, further comprising: before manually resetting the switch, unlocking a mechanical protection structure to physically access the mechanical mechanism.
