检查dts配置发现&usbdrd_dwc3_0 配置为host模式，但硬件上配置是otg模式，将&usbdrd_dwc3_0配置更改为otg模式。

    arch/arm64/boot/dts/rockchip/rk3399-box.dtsi&usbdrd_dwc3_0 {dr_mode = "otg";status = "okay";};

查看中断信号，发现usb中断触发时，显示仍是host模式，再次检查发现在rk3399-android.dtsi中有对&usbdrd_dwc3_0的覆盖配置，删除rk3399-android.dtsi中的&usbdrd_dwc3_0配置

arch/arm64/boot/dts/rockchip/rk3399-android.dtsi-&usbdrd_dwc3_0 {-       dr_mode = "host";-    phys = <&u2phy0_otg>;-    phy-names = "usb2-phy";-    maximum-speed = "high-speed";-    status = "okay";-};
