Jetson Nano USB Ports Not Working - Unable to Connect Peripherals or Access Internet

[rifathoshen]

Hello NVIDIA Community,

I am experiencing a recurring issue with my Jetson Nano where the USB ports suddenly stop working, preventing me from connecting peripherals like a keyboard, mouse, and WiFi module. This issue persists despite several troubleshooting attempts, and I’m seeking assistance to resolve it.

Device Details:

• NVIDIA Jetson Nano (4GB)
• Operating System: Ubuntu (Latest jetpack for jetson nano)
• Power Supply: (5V 4A)

Issue Description:

• Initially, the USB ports function normally, but they stop working after some time.
• When the issue occurs, connected devices like the keyboard, mouse, and WiFi module are not recognized and do not function.
• The problem persists even after re-flashing the SD card with a fresh OS installation.

Troubleshooting Steps Taken:

1. Re-flashed the SD card with a new installation of the OS.
2. Checked and confirmed the power supply is adequate (5V/4A).
3. Connected to the Jetson Nano via a serial port from a Windows host for command-line access.

Current Challenge:

• Without functional USB ports, I cannot connect to the internet as the WiFi module is not recognized. Running sudo apt-get update fails due to the lack of internet connectivity.
• The serial connection is my only means of interfacing with the Jetson Nano at this point.

I would greatly appreciate any insights, suggestions, or solutions that could help me resolve this issue. Has anyone else encountered similar problems with their Jetson Nano? Any advice on additional troubleshooting steps or potential fixes would be immensely helpful.

Thank you in advance for your assistance!

Please share me the dmesg after you boot up with serial console.

and another picture if I connect via serial port 4 on my windows host via putty

Hi,

I need you to enter command “dmesg” in that putty and copy and paste every log as a file and attach it here.

Please attach it as a file instead of directly copy and paste…

Looks like the hub on the board is dead. This board needs RMA.

Should I buy a new carrier board ?
Is my jetson nano processor is good ?
Or both of these are unable to be used (broken).
Please suggest to me what I should do now.

I guess the nano module is still working. You could get a new module for cross check.
