Automatically configuring a universal serial bus (USB) type-C port of a computing device

A computing device comprising:

• one or more processors;
• one or more memory storage devices;
• one or more universal serial bus (USB) Type-C ports;
• a device bus;
• a cross-point switch;
• and
• a logic device configured to perform operations comprising:
• receiving an indication from a port controller that an external device is connected via a cable to a particular universal serial bus (USB) Type-C port of the one or more USB Type-C ports;
• in response to receiving the indication, determining a role of the external device;
• in response to determining the role of the external device, determining a device class of the external device;
• and
• in response to determining, based on the role and the device class, that the external device comprises a display device, sending an instruction to the cross-point switch to connect at least a video bus to the USB Type-C port;
• in response to determining, based on the role and the device class, that the external device comprises a storage device, sending, by the logic device, an instruction to the cross-point switch to connect at least a device bus to the USB Type-C port;
• and
• in response to determining, based on the role and the device class, that the external device is requesting that power be provided, sending by the logic device, an instruction to the cross-point switch to connect at least a power bus to the USB Type-C port.

An embedded controller programmed with instructions to perform operations comprising:

• receiving an indication from a port controller that an external device is connected via a cable to a universal serial bus (USB) Type-C port of a computing device, wherein the computing device comprises:
• the embedded controller,
• a cross-point switch coupled to the embedded controller,
• the USB Type-C port, and
• a device bus;
• in response to receiving the indication, determining a device class of the external device;
• in response to determining the device class, determining a role of the external device;
• in response to determining, based on the role and the device class, that the external device comprises a display device, instructing the cross-point switch to connect at least a video bus to the USB Type-C port;
• in response to determining, based on the role and the device class, that the external device comprises a storage device, instructing the cross-point switch to connect a device bus to the USB Type-C port;
• and
• in response to determining, based on the role and the device class, that the external device is requesting that power be provided, instructing the cross-point switch to connect at least a power bus to the USB Type-C port.
