The OP-COM USB V2 Interface is a diagnostic tool used primarily for OBD-II (On-Board Diagnostics) communication with vehicles, especially Opel and Vauxhall cars. It is often used for tasks like reading and clearing diagnostic trouble codes (DTCs), checking vehicle sensor data, and performing various service functions such as resetting service lights or programming keys.

The OP-COM USB V2 Interface is the hardware interface device that connects your car's OBD-II port to your computer via USB. The driver for the OP-COM interface allows your Windows PC to communicate with this hardware interface, enabling diagnostic software to interact with your vehicle's onboard computer.
