Warnings
This USB hub is cheap and has backfeeding issue. We should not buy it a second time. The power wiring was cut in the regular power source cable to prevent this backfeeding effect. We kept only the data bus (2 remaining wires). That means that the hub power comes from Traco Power TMA 2405S only. See General power/wiring concept, consumptions and temperatures for description.
