because firefly_rk3399 use the type-c by otg mode,but there is different both otg wire and defualt wire. so if you want to use the default wire,you can chang the otg mode ,modify dts,chang the &&usbdrd3_0 to &u2phy0

&usbdrd3_0 {        status = "okay";        //extcon = <&fusb0>;        extcon = <&u2phy0>;}; &usbdrd_dwc3_0 {        status = "okay";        dr_mode = "otg"; /* Micro USB3控制器的dr_mode配置为otg */        maximum-speed = "high-speed"; /* maximum-speed 属性配置为high-speed */        phys = <&u2phy0_otg>; /* phys 属性只引用USB2 PHY节点 */        phy-names = "usb2-phy";};
