The redesigned USB connector, belonging to the USB 3.1 specification, could be in laptops and mobile devices by the end of the year. The appealing advances in the USB 3.1 technology include faster data transfer speeds and the user-friendly Type C connector, which connect to devices on either end. Since users won't have to worry about plug orientation, they should be less likely to have trouble fitting cables into slots, which will be an improvement over USB connectors.
