USBs are not working on custom carrier card for L4T28.2 and TX2i

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX2

We have custom carrier cards and had to change vbus-3-supply in dtb to have USB3 working for L4T 28.1.
With L4T 28.2, however, neither USB2 nor USB3 are working, the light of mouse turns on, but there is no cursor. USBs worked for the same TX2i on Nvidia TX2 carrier card.
The following are part of kernel logs:

Thanks in advance for suggestions to troubleshoot.

You should make same change to vbus-3-supply for r28.2 Jetson/TX2 USB - eLinux.org

Wrong ‘vbus-3-supply’ triggers below error

[    4.403045] xhci-tegra 3530000.xhci: can't get usb3-0 phy (-517)

I changed

vbus-0-supply = <0x9a>;
		vbus-1-supply = <0x9b>;
		vbus-2-supply = <0x9c>;
		vbus-3-supply = <0x19>;
		vddio-hsic-supply = <0x19>;

to

vbus-0-supply = <0x9a>;
		vbus-1-supply = <0x9b>;
		vbus-2-supply = <0x19>;
		vbus-3-supply = <0x19>;
		vddio-hsic-supply = <0x19>;

and it worked.
Thanks

Hi,

I also faced the same problem.
I made the following change:
Edited file:
hardware/nvidia/platform/t18x/common/kernel-dts/t18x-common-platforms/tegra186-quill-power-tree-p3489-1000-a00-00.dtsi

pinctrl@3520000 {
                vbus-0-supply = <&vdd_usb0_5v>;
                vbus-1-supply = <&vdd_usb1_5v>;
                /*vbus-2-supply = <&vdd_usb2_5v>;  Orig line*/
                vbus-2-supply = <&battery_reg>; /*fix USB issue*/
                vbus-3-supply = <&battery_reg>;
                vddio-hsic-supply = <&battery_reg>;
                avdd_usb-supply = <&spmic_sd3>;
                vclamp_usb-supply = <&spmic_sd2>;
                avdd_pll_erefeut-supply = <&spmic_sd2>;
        };

created DTB file:

make O=$TEGRA_KERNEL_OUT dtbs

copied the tegra186-quill-p3489-1000-a00-00-ucm1.dtb file to
kernel/dtb

burn new dtb:

sudo ./flash.sh -r -k kernel-dtb jetson-tx2i mmcblk0p1

As a result I have a working USB.
But I noticed 1 thing I didn’t saw before:
When I run ifconfig I got too much interfaces)

Can you help me to understand what all those devices are doing here?
I mean: docker0 , l4tbr0, usb0 and usb1.

I’m also attaching some dmesg here
