@bb-qq how can i debug this issue?

[bb-qq]

When the dongle is connected to a PC, does it work correctly as expected? I would like to confirm this is not auto-negotiation or other issues of ethernet connectivity.

Using on my macbook, due to the mac driver problem, it can be detected and work as a 1G NIC, and connect to the switch.

When used on the NAS, I tried the different ports, such as a fixed 1G, a fixed 100M, an auto-nego 10/5/2.5G port, and get the same problem.

[bb-qq]

I have no idea what is causing the problem. Perhaps the device is underpowered and a self-powered USB hub to which an AC adapter can be connected might help, but I do not have confidence.

[bb-qq]

The latest driver might improve the situation since it includes some minor changes.
