If a data transfer start request is received from a USB device using application and if the requested communication speed is a high speed communication mode, the communication speed mode of the USB controller is changed to a high speed mode through the USB driver. The USB application estimates the transfer rate required for the data transfer to be executed and, if the estimated transfer rate is higher than the full speed mode or the transfer rate resulting from subtraction of a predetermined margin from the full speed, the requested communication speed is set to the high speed or is set to full speed otherwise."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication apparatus and method for communicating with an external device through USB interface using a high-speed or low-speed communication mode","description":"A communication speed control application sets the initial communication mode of the USB controller to a full speed mode through a USB driver.
