Electronic Device Arrangement, Method for Operating an Electronic Device Arrangement, Security Device, and Automated Teller Machine

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).

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.
