Among them it supports Alternate Mode, which allows transporting other protocols via the USB-C connector and cable. A USB cable, by definition, has a plug on each end—one A (or C) and one B (or C)—and the corresponding receptacle is usually on a computer or electronic device. For example, Apple's iPod and iPhone chargers indicate the available current by voltages on the D− and D+ lines. A number of extensions to the USB Specifications have progressively further increased the maximum allowable V_BUS voltage: starting with 6.

To recognize Battery Charging mode, a dedicated charging port places a resistance not exceeding 200Ω across the D+ and D− terminals. ft, 192 000 km/s), which is close to the maximum achievable transmission speed for standard copper wire.Upstream USB connectors supply power at a nominal 5V DC via the V_BUS pin to downstream USB devices. The host controller directs traffic flow to devices, so no USB device can transfer any data on the bus without an explicit request from the host controller.

USB cables and small USB devices are held in place by the gripping force from the receptacle, with no screws, clips, or thumb-turns as other connectors use. The Mini-USB connectors (Mini-A, Mini-B, Mini-AB) were introduced for mobile devices, but they were quickly replaced by the thinner Micro-USB connectors (Micro-A, Micro-B, Micro-AB). The Micro plug design is rated for at least 10,000 connect-disconnect cycles, which is more than the Mini plug design. The ID pin of the OTG port is not connected within plug as usual, but to the ACA itself, where signals outside the OTG floating and ground states are used for ACA detection and state signaling. and USB4Gen2×1 – are not interchangeable or compatible; all participating controllers must operate with the same mode.On the device side, a modified Micro-B plug (Micro-B SuperSpeed) is used to cater for the five additional pins required to achieve the USB 3. The fact that there is no clock line within the USB cable leads to a thinner cable, which is an advantage. The PCI Express function of USB4 replicates the functionality of previous versions of the Thunderbolt specification.

Isochronous transfers At some guaranteed data rate (for fixed-bandwidth streaming data) but with possible data loss (e. Additional requirements for a more rugged connector that is durable past 10,000 cycles and still meets the USB 2.Original Thunderbolt implementations have two channels, each with a transfer speed of 10Gbit/s, resulting in an aggregate unidirectional bandwidth of 20Gbit/s. SuperSpeed and SuperSpeedPlus operation modes but introduces two new SuperSpeedPlus operation modes with the new USB-C Fabric with signaling rates of 10 and 20Gbit/s (nominal data rates of 1212 and 2424MB/s). SuperSpeed (SS) adds two additional pairs of shielded twisted data wires (and new, mostly compatible expanded connectors) besides another grounding wire. Devices that use MA-USB will be branded as 'Powered by MA-USB', provided the product qualifies its certification program. backward-compatibility resulting in 9 wires (with 9 or 10 pins at connector interfaces; ID-pin is not wired) in total.
