3-5-3(c) Cable

USB cable consists of four conductors, two power conductors, and two signal conductors. High-/full-speed cable consists of a signaling twisted pair, VBUS, GND, and an overall shield. High-/full speed cable must be marked to indicate suitability for USB usage. High-/full-speed cable may be used with either low-speed, full-speed, or high-speed devices. When high-/full-speed cable used with low-speed devices, the cable must meet all low-speed requirements.

Low-speed recommends, but does not require the use of a cable with twisted signaling conductors.
