In some implementations a logic device, such as an embedded controller, automatically configures a universal serial bus (USB) Type-C port by connecting the USB Type-C port to appropriate input/output (I/O) signals. For example, the logic device may receive a notification that an external device is connected to a USB Type-C port of a computing device. The logic device may receive data from a port controller over an internal communication bus associated with the USB Type-C port. Based at least in part on the data, the logic device may determine one or more types of signals that the external device is configured to send, receive, or send and receive. The logic device may instruct a cross-point switch to connect the USB Type-C port to one or more signal paths in the computing device to enable the external device to send/receive the one or more types of signals.
