Hello,

We have to connect 2~3 eth port to AGX Orin Developer Kit.
So, we are using ‘usb to eth’ cable.

There is a issue when we use multipe ‘usb to eth’ port.

  1. usb c (x1) => no issue
  2. usb c (x2) => only 1 port has established and another doesn’t recognized.
  3. usb c (x1) + usa a (x1) => no issue

I wonder no.2 case, what is the problem??

Hi,

For this case, which type-C port do you use on Orin developer kit? And you connect to a USB hub and then to two USB to Ethernet dongles? Would like to get more information to understand the error case.

1. USB A (x1) and USB C (x1)
