Hi folks,
I'm having exactly the same problem. I've had the Link for 5 years and everything works fine on the old desktop that I retrieved from my loft (with serial connector) but the modern laptop with USB only is a non-starter. I've established today that not all adapters are created equal and that there may be a compatibility problem between the adapter and ECU. Hopefully, I will receive another adapter next week that will cure the problem. Fingers crossed. I hope it does, desktops are not a great tool for datalogging. I probably won't have an answer before 16/10 but will let you know if the cable change helped.
Tony
