How does Type C detect a USB connection?
Type-C Connection/ Orientation Detection (Source: Cypress Semiconductor) R p and R d termination resistors on the Type-C receptacle CC pins make it possible to detect the connection event and identify the orientation of the Type-C plugs in the receptacles.
What are the pins on a USB Type C receptacle?
On a USB Type-C receptacle, two sets of SuperSpeed USB signal pins are defined to enable the plug-flipping feature. The USB 2.0 serial data interface defines a differential pair. On a USB Type-C receptacle, two sets of USB 2.0 signal pins are defined to enable the plug-flipping feature.
How are SBU signals used in USB receptacle?
The CC channel in the receptacle detects the signal orientation and channel configuration. Sideband Use. SBU signals are used in the Alternate Mode supported by the Type-C specification, which enables multi-purposing of Type-C signals for alternate uses such as DisplayPort Table 2.

Where is the v Conn pin on a Type C cable?
These non-EMCA cables leave the V CONN pin floating on the Type-C plug. For more details on implementing EMCA, see Designing a Type-C Electronically Marked Cable and Designing USB 3.1 Type-C Cables. Figure 6. Type-C Connection/ Orientation Detection (Source: Cypress Semiconductor)
Which is the power pin on a USB Type C plug?
The Type-C plug offers only one CC pin, which is connected to one of the CC pins of the Type-C receptacle, to establish the Type-C orientation. The other CC pin is repurposed as VCONN (abbreviation for V CONNECTOR ) for powering the electronics in the USB Type-C plug.
How are differential pins defined in USB Type C?
The SuperSpeed USB serial data interface defines a differential transmit pair and a differential receive pair. On a USB Type-C receptacle, two sets of SuperSpeed USB signal pins are defined to enable the plug-flipping feature. The USB 2.0 serial data interface defines a differential pair.
