Type-C USB connectors can be used with adapters that allow the connection of various other USB types, and they are capable of transferring power and data to/from all previous generations of USB devices. Cabling [ edit ] A USB twisted pair, in which the Data+ and Data− conductors are twisted together in a double helix.For example, Apple's iPod and iPhone chargers indicate the available current by voltages on the D− and D+ lines. at all locations for high-power [b] devices (however, high-power devices are required to operate as a low-powered device so that they may be detected and enumerated if connected to a low-power upstream port).

Optionally, the hub controller may draw power for its operation as a low-power device, but all high-power ports must draw from the hub's self-power.
