Hi,
Here is a example of device tree:
USB not working in Jetson TX2 - R32.2 - #2 by DaneLLL

If the lanes are set to USB3, please remove them from:

			pcie {
				status = "okay";

				lanes {
					pcie-0 {
						status = "okay";
						nvidia,function = "pcie-x4";
					};
					pcie-1 {
						status = "disabled";
						nvidia,function = "pcie-x1";
					};
					pcie-2 {
						status = "disabled";
						nvidia,function = "pcie-x1";
					};
					pcie-3 {
						status = "okay";
						nvidia,function = "xusb";
					};
					pcie-4 {
						status = "okay";
						nvidia,function = "pcie-x1";
					};
					pcie-5 {
						status = "okay";
						nvidia,function = "xusb";
					};
					pcie-6 {
						status = "okay";
						nvidia,function = "xusb";
					};
				};
			};

			sata {
				status = "okay";

				lanes {
					sata-0 {
						status = "okay";
						nvidia,function = "sata";
					};
				};
			};

			hsic {
				status = "okay";

				lanes {
					hsic-0 {
						status = "okay";
						nvidia,function = "xusb";
					};
				};
			};

You should have setting like:

        usb3 {
            lanes {
                usb3-0 {
                    nvidia,function = "xusb";
                    status = "okay";
                };
                usb3-1 {
                    nvidia,function = "xusb";
                    status = "okay";
                };
            };

And on r32 releases, it is not required to set fake port. Please modify this:

		ports {
			usb2-0 {
				status = "okay";
				mode = "otg";
				nvidia,usb3-port-fake = <3>;
			};

And please set vbus-supply for each port.
