Jetpack 7.2.1 SSH connection issue with macOS

Hello,

I am using a Jetson Orin Nano (Jetpack 7.2.1) and trying to connect to it from a Macbook Air (m5) over the default USB virtual Ethernet interface (192.168.55.1) for SSH.

With Jetpack 7.2.1, the Jetson side appears to be configured correctly:
l4tbr0: 192.168.55.1
usb0: UP / LOWER_UP
usb0 is attached to l4tbr0
nv-l4t-usb-device-mode.service: active
UDC: 3550000.usb
UDC state: configured
sshd is listening on port 22

On both Ubuntu and Window hosts, the same Jetson and USB connection work correctly.

On macOS, the device is detected as:
Hardware Port: Linux for Tegra
Device: en5

But the interface remains:
status: inactive

and ping 192.168.55.1 , ssh -p 22 ``user@192.168.55.1 fails.

I then downgraded the same board to Jetpack 6.2.1. After the downgrade, SSH over 192.168.55.1 work normally on the same Macbook Air.

Has anyone seen a similar issue with Jetpack 7.2.1 and macOS USB Ethernet?

Hi,
For information, do you use Orin Nano developer kit? Or a custom board?

Hi,
For connecting to host through USB virtual Ethernet, we would suggest have host in Linux Ubuntu OS, and connect through type-A to type-C cable. Type-C to type-C cable or other OSs may not work properly.
