Usb usb2-port 3 cannot enable. maybe the usb cable is bad?

Hi @WayneWWW ,
No its not that AGX.
Today I was working on a different AGX.
I was using UART but I wasn’t able to send or recieve any data so I reboted the AGX and this happened?
these are the commands I used

$ systemctl stop nvgetty
$ systemctl disable nvgetty
$ udevadm trigger 

Please Help to fix this Xavier.
Can you please also let me know how to fix the other two AGX which I mentioned yesterday in this thread

If possible Can we have a call through Google meet?
