The receptacle features 4 energy and 4 floor pins, two differential pairs (linked together on units) for vapeanchor legacy USB 2.0 excessive-speed knowledge, 4 shielded differential pairs for Enhanced SuperSpeed data (two transmit and two obtain pairs), two Sideband Use (SBU) pins, and two Configuration Channel (CC) pins. USB 2.Zero Type-C cables do not embody wires for SuperSpeed or sideband use. USB-C gadgets could optionally provide or eat bus power currents of 1.5 A and 3.0 A (at 5 V) along with baseline bus power provision; power sources can either promote elevated USB current through the configuration channel or implement the total USB Power Delivery specification using both the BMC-coded configuration line and the legacy BFSK-coded VBUS line.

The plug has only one USB 2.Zero high-velocity differential pair, and one of many CC pins (CC2) is replaced by VCONN, to power non-compulsory electronics within the cable, and the opposite is used to really carry the Configuration Channel (CC) signals. Furthermore, Dual-Role tools that implements USB Power Delivery may swap knowledge and newest vapor energy roles independently using the data Role Swap or Power Role Swap processes. For any two items of gear connecting over USB, newest vapor (a cool way to improve) one is a host (with a downstream-going through port, DFP) and the opposite is a peripheral gadget (with an upstream-facing port, UFP).

Similarly, a trendy gadget can connect to a legacy host through the use of a legacy cable with a USB-C plug on the gadget end and a normal-A plug on the host end. Connecting legacy and modern, USB-C equipment requires both a legacy cable meeting (a cable with any Type-A or Cheapest Vape Type-B plug on one end and vape online retailer a sort-C plug on the opposite) or, in very particular circumstances, a legacy adapter meeting. With USB-C, when two such units are connected, the roles are first randomly assigned, however a swap could be commanded from both end, although there are elective path and position detection methods that will enable gear to select a desire for a specific position.

There are exceptions for circumstances where the USB-C wire is straight connected to a machine at one finish to permit these devices to be powered by VCONN. Legacy adapters with USB-C receptacles are "not outlined or allowed" by the specification as a result of they can create "many invalid and potentially unsafe" cable mixtures (being any cable assembly with two A ends or two B ends). All older USB connectors (all Type-A and Vape Starter Kits type-B) are designated legacy.

An older device can connect with a fashionable (USB-C) host through the use of a legacy cable, with an ordinary-B, Mini-B, newest vapor or Micro-B plug on the gadget end and a USB-C plug on the other.

An Alternate Mode dedicates a few of the bodily wires in a USB-C cable for Vape Starter Kits direct device-to-host transmission utilizing non-USB knowledge protocols, akin to DisplayPort or Thunderbolt.
