    I wonder what this “Higher Power Consumption” means and why that is. Higher than USB-4 or higher than other USB-A slots? I would except a USB-A slot to not use more power than a USB-4 slot.

      IIRC There’s an issue with the retiming chips that retransmit the USB4 signals over to the A style and how they’re able to interact with the rest of the system. It causes the chips to stay awake and waste energy. The same issue is present on the AMD 13 framework; something to do with the AMD USB4 implementation. The 3.2 ports don’t have the same issue.

      Basically the port will still work in that configuration but the battery life will suffer.
