Hi,
We had a previous discussion here:
It took us a while to extract valuable logs from the serial interface, and here it is attached.
jetson_log_b12.txt (593.2 KB)
I’d appreciate any help with that.
Kind regards,
Moti.
Hi moti4,
Are you using the devkit or custom board for Xavier NX?

From the log you shared, it seems caused from USB device.
Do you connect multiple USB devices on your setup?
[2025-02-09 18:38:53]-[282029.403972] usb 2-3.2: usbfs: process 12471 (.NET ThreadPool) did not claim interface 0 before use
[282029.422093] usb 2-3.2: usbfs: process 20132 (0-1) did not claim interface 1 before use
It indicates that the .NET ThreadPool process does not claim USB interface before use. Or it may be caused from multiple process request for the same USB port.
Could you share the steps how do you reproduce the issue?
Hi,
I am Moti4’s teammate.
Regarding your questions:
We are using DevKit and connecting multiple USB devices.
We have not been able to reproduce the issue because we do not know what leads to the system hanging. This occurs every few days without a clear pattern.
Kind regards,
Tehila
Would you hit the issue if you remove all USB devices?
If not, please help to clarify which USB device causes this error and let us know what you are running.
