USB0识别不了U盘。

设备树如下：

&usb {
status = "okay";
};

&usb_ctrl_mod {
status = "okay";
};

&usb0_phy {
status = "okay";
};

&usb1_phy {
status = "okay";
};

&usb0 {
status = "okay";
dr_mode = "host";
};

&usb1 {
status = "okay";
//dr_mode = "host";
dr_mode = "otg";
};

&cppi41dma {
status = "okay";
};

启动打印log：
