TX2 Custom Board USB Problem

r1ch13r1ch · April 13, 2018, 2:09pm

Hi,

I’m using a custom carrier board, which has a TUSB8041 USB hub. My L4T version is 28.1 and i flash module using Jetpack 3.1. Configuration in use is #2(Default CB). Unfortunately, I cant use any USB device on this custom board. “lsusb” command shows nothing. This is the output of “dmesg | grep usb”.

This is the full output of “dmesg”,
https://pastebin.com/6p5y2tYc

I tried modifying DTB, using this guide:
https://elinux.org/Jetson/TX2_USB
After this modification, module was not able to boot. Nothing appears when powered on.

Referring to this post,
https://devtalk.nvidia.com/default/topic/1028223/jetson-tx2/tx2-usb-not-work/post/5232118/#5232118
I dont make any changes on BCT/*.cfg files.

How can i fix this issue? Any help would be highly appreciated.

Kind regards.

Hi,

Thank you for your response.

I followed the instructions on the link you gave. This is what i changed:

tegra186-quill-power-tree-p3310-1000-a00-00.dtsi → vbus-2-supply = <&battery_reg>;

Since the configuration number is 2, i didnt changed any other files.

Now, lsusb command gives the following output,

Bus 002 Device 002: ID 0451:8140 Texas Instruments, Inc. 
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

This is the output of dmesg when i plug an usb device,

Usb hub is connected to USB_SS0.

Do you have any suggestion about this?

Thanks.

Still stuck on this. I would be very pleased if someone can help me asap. Thanks.

r1ch13r1ch · April 18, 2018, 12:28pm

Now my USB ports only work with USB3.0 capable devices. USB 2.0 devices gives the “device descriptor read/64, error -32”, which seems like a broken pipe error. Also, USB3.0 devices may not be recognized in first plug or after booting plugged. And after replugging the device, it connects succesfully. What can cause these issues?

hi r1ch13r1ch,
What is your HW design for VBUS pins? Do you pull the pins up after booting to kernel?

r1ch13r1ch · April 20, 2018, 1:17pm

Hi,

Thank you for your reply.

Type C VBUS pins connected to power through regulator. And the regulator is controlled by usb hub. I am not pulling the pins up manually.

Hi r1ch13r1ch, you use Type C connector? Not Type A?

r1ch13r1ch · May 3, 2018, 6:56am

Yes, i am using Type C connectors.

DaneLLL · May 3, 2018, 7:51am

Hi,
For USB Type C connector, we suggest HW design as shown at
