You're right it's a brand new socket as it's a USB C-Type. But the shape of the connection does really make a difference? In the garage they just put an adaptor to the classic USB and it works with their software...
Or maybe you're right and the laptop doesn't match the USB type? I mean my laptop, quite new, has Only C-Type USBs. So I connect direct USB C-type to C-type. But again, I'm not a specialist in informatics but I don't believe the cable the problem...
In fact, my laptp says there is a ECU unit, but that he doesn't have the proper driver. So, it communicates / detects the ECU which to my limited knowledge means the cable is not the issue.
I guess I'll contact S&S tomorrow and see if they can / want help me out…
Keep trying is the only way!
