Could you share your full dmesg?

[Seven0]

thank you reply,
this is full dmesg
usb.log (328.9 KB)

[WayneWWW]

This log is not from jetpack5.1.2… Jetpack5.1.2 kernel version is not 5.10.104.

[Seven0]

yes，because I first found this error on 5.0.2, saved the log, and then tried to find the same issue on 5.1.2, but I did not connect the serial port and did not print the log in 5.1.2

[WayneWWW]

This issue shall already be resolved on jp5.1.2. Please dump full log from 5.1.2.

Hello,WayneWWW
This is my first time using usb wifi. Connect to wifi after login, error log:
usb_wifi2.log (517.5 KB)

If usb wifi is not removed,orin cannot be turned on. Error log:
usb_wifi.log (500.9 KB)

[WayneWWW]

Could you share what kind of device you are using here? any website that can buy such card?

And is this on devkit or custom board or you don’t know what I am talking about?

[Seven0]

usb wifi is Sagem XG-76NA model，I’m not sure where to buy at the moment, please let me check.
I use devkit.
