A603 with Orin NX, usb A ports not working


I have an Orin NX that I’m using with an A603 carrier board. I just flashed it with Jetpack 5.1.1 and L4T 35.3.1 to NVMe SSD memory according to this wiki A603 Carrier Board | Seeed Studio Wiki.

Now the system boots, but only the micro-usb port is functional. The system doesnt recognize usb devices plugged into the other ports (i.e., the result of “lsusb” doesnt change).

Can you help me with that? Am I missing drivers or something?


I’ve had a similar Problem. I’ve falshed the Jetson with L4T35.4.1 and it worked for me.
