Systems and methods of controlling communication modes in an electronic device

A secondary device, comprising:

• a USB-C port;
• a universal serial bus (USB) hub having a plurality of ports;
• a DisplayPort (DP) processor;
• a multiplexer in electrical communication with the USB-C port, wherein the multiplexer is configured to switch a four-lane data connection between the USB hub to the DP processor;
• a microcontroller in data communication with the multiplexer;
• and
• a storage device electrically coupled to the microcontroller having instructions stored thereon that instruct the microcontroller
• establishing a first communication link with a downstream device using a first mode via a USB-type interface, of one or more additional USB-type interfaces, wherein in the first mode the USB-type interface utilizes a first set of USB communication lanes;
• establishing a second communication link with the first device via the USB-C port using an Alternate mode (Alt-mode) wherein the Alt-mode utilizes the first set of USB communication lanes;
• and
• in accordance with establishing the second communication link and based on the Alt-mode utilizing the first set of USB communications lanes, changing a mode of the first communication link so that the first communication link does not communicate via the first set of USB communication lanes.
