Abstract
A merchant terminal has two USB interfaces. Each USB interface includes a voltage pin and an ID pin. The merchant terminal also has two power supply switches, each of which selectively couples a respective one of the voltage pins to a merchant terminal power supply. Each power supply switch is responsive to either a power supply voltage received at an associated voltage pin or an oscillating signal received at an associated ID pin.
