I bought a new electrician on bricklink.com (bb0961c01, bb0959c01, bb0960c01) and I can’t connect the hub to the lego control+. The hub establishes only two connections (as I understand it) out of four, after which it disconnects. Brickcontroller 2 establishes a connection with the hub, I can control the engines, but then only those that are connected to the C and D ports, and any engines in them work, even my old M-motors. The motors that are connected to ports A and B cannot be controlled; nothing happens when the sliders are moved.
Did anyone have this? Software problems or hub broken? Can I connect incorrectly? Here is the unboxing video.
