Abstract
A host electronic device that supports both Universal Serial Bus (USB) and Controller Area Network (CAN) connections is provided. The host electronic device drives at least one USB signal line and measures the voltage thereof. When the measured voltage indicates a USB connection from a peripheral device, the host electronic device determines that the peripheral device is a USB device. Otherwise, the host electronic device determines that the peripheral device is a CAN device.
