The USB is not recognized. The SoC is iMX8Mini(MIMX8MM6CVTKZAA). Please tell me the cause by referring to the device tree settings below.

&usbotg2 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usbotg2>;
power-active-high;
disable-over-current;

dr_mode = "peripheral";
status = "okay";
phy_type = "utmi";
phys = <&usbphynop2_alt>;
phy-names = "usb";

port {
typea_hs: endpoint {
remote-endpoint = <&typea_con_hs>;
};
};
};


&soc {
usbphynop2_alt: usbphynop@381f0040 {
compatible = "usb-nop-xceiv";
reg = <0x381f0040 0x40>;
#phy-cells = <0>;
status = "okay";
};
};
