It has two USB (male) connectors, one USB 3.0, and another USB 2.0 for power only and data. ・Connector type 1: USB3.0 (Standard-A) male + USB2.0 (Standard-A) male Connector type 2: USB3.0 (Standard-A) female x 1 ・USB 3.0 extension cable (Type A male to Type A female): This cable extends the connection of peripherals with USB 3.0 connectors, such as computers, printers, and card readers.
