RouterOS 7.23rc1 – USB Ethernet (DUB-E250) missing link info + incorrect link state on hAP ax3

Hi,

I’m testing RouterOS 7.23rc1 on a hAP ax3 and ran into a couple of issues with a USB Ethernet adapter.

Setup:

  • Device: hAP ax3

  • RouterOS: 7.23rc1

  • USB NIC: D-Link DUB-E250 (USB 3.0)

  • Interface: ether6 (USB)


Issue 1 – Missing link parameters

On the USB interface (ether6):

  • Rate is empty

  • Full Duplex is empty

  • Auto Negotiation shows "incomplete"

The interface does not report link characteristics at all, even when connected.


Issue 2 – Wrong link state behavior

I connected:

  • ether1 (2.5Gbps port) ↔ ether6 (USB adapter)

When I disable ether6, I would expect ether1 to lose link.

However:

  • ether1 still shows "running" with "link ok"

This suggests link state is not properly propagated or detected when using the USB Ethernet driver.


Additional info

  • USB device is correctly detected under /system resource usb

  • No relevant errors in logs

  • Issue is reproducible


If needed, I can provide supout.rif or run additional tests.

Has anyone else seen similar behavior with USB NICs on RouterOS 7.23rc1?
