Ah- thanks! I know the port is blue and the label says “3.0”, but it’s nice to be sure.
And, now I know why 2.5GBit (and only a 1GBit) adaptors are supported in Beta8, and some are not- notice that’s the CDC-NCM driver, and not the RealTek driver. Now I wonder if I’m connected in Full-Duplex mode (many RealTek devices don’t connect in FDX when connected via CDC-NCM).
