The USB trident symbol, a long-standing identifier for USB ports, has evolved in meaning over the years, leading to confusion for consumers. Initially denoting USB 2.0, the symbol has been updated with accompanying text like "SS" and speed indicators (e.g., 5Gbps, 10Gbps, 20Gbps) to represent newer USB 3.x generations. Port colors also offer clues, with black or white typically indicating USB 2.0, blue for USB 5Gbps, and red or yellow often signifying higher speeds or power delivery capabilities, though manufacturers are increasingly encouraged to rely on symbols for clarity.
