A controller is used to implement a DRP-compliant device that can be both power supply side and power reception side according to the USB Type-C standard. The controller is configured to be able to execute a first process of determining whether or not the Port Power Role of the opposing device is Try.SRC when the Power Role of the own device is determined to be Sink meaning the power receiver according to the sequence with the opposing device, which is the connected device, and a second process of switching the Port Power Role of the own device to SRC only and continuing the sequence with the opposing device if the Port Power Role of the opposing device is Try.SRC."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Controller, control method, and control program","description":"The present invention solves a new problem that may occur when Try.SRC or Try.SNK is adopted.
