Thunderbolt 3 (also carries 4× PCI Express 3.0, DisplayPort1.2, DisplayPort1.4, USB 3.1 Gen 2), [30] [31] [32] [33] Contrary to other functions – which use the multiplexing of high-speed links – USB 2.0 over USB-C utilizes its own differential pair of wires. The receptacle features four power and four ground pins, two differential pairs (connected together on devices) for legacy USB 2.0 high-speed data, four shielded differential pairs for Enhanced SuperSpeed data (two transmit and two receive pairs), two Sideband Use (SBU) pins, and two Configuration Channel (CC) pins. USB 4 on the other hand is a data transfer protocol compatible with USB-C and other connectors. It also uses the same small, reversible connector as USB-C, making it very simple to use. Data Transfer Speed

An older device can connect to a modern (USB-C) host by using a legacy cable, with a Standard-B, Mini-B, or Micro-B plug on the device end and a USB-C plug on the other. Similarly, a modern device can connect to a legacy host by using a legacy cable with a USB-C plug on the device end and a Standard-A plug on the host end. Legacy adapters with USB-C receptacles are "not defined or allowed" by the specification because they can create "many invalid and potentially unsafe" cable combinations (being any cable assembly with two A ends or two B ends). However, exactly two types of adapter with USB-C plugs are defined: one with a Standard-A receptacle (for connecting a legacy device (such as a flash drive—not a cable) to a modern host, and supporting up to USB 3.1), and one with a Micro-B receptacle (for connecting a modern device to a legacy host, and supporting up to USB 2.0).

The plug has only one USB 2.0 high-speed differential pair, and one of the CC pins (CC2) is replaced by V CONN, to power optional electronics in the cable, and the other is used to actually carry the Configuration Channel (CC) signals. These signals are used to determine the orientation of the cable, as well as to carry USB Power Delivery communications.

Finally, while USB 4 is more expensive than USB-C, the additional speed and functionality it offers make it worth the investment.

Standard USB hub ports can provide from the typical 500mA/2.5W of current, only 100mA from non-hub ports. USB3.0 and USB On-The-Go supply 1.8A/9.0W (for dedicated battery charging, 1.5A/7.5W full bandwidth or 900mA/4.5W high bandwidth), while FireWire can in theory supply up to 60watts of power, although 10 to 20watts is more typical. The functionality of a USB device is defined by a class code sent to a USB host.

No, Thunderbolt cable is not the same as USB-C. Thunderbolt uses a USB-C connector but requires special cables that support the Thunderbolt protocol. USB-C cables may not be compatible with Thunderbolt devices. The USB Device Working Group has laid out specifications for audio streaming, and specific standards have been developed and implemented for audio class uses, such as microphones, speakers, headsets, telephones, musical instruments, etc. The working group has published three versions of audio device specifications: [65] [66] USB Audio1.0, 2.0, and 3.0, referred to as "UAC" [67] or "ADC". [68] A device with a Type-C connector does not necessarily implement any USB transfer protocol, USB Power Delivery, or any of the Alternate Modes: the Type-C connector is common to several technologies while mandating only a few of them. [6] USB4 products may optionally offer interoperability with the HDMI, MHL, and VirtualLink Alternate Modes.
