Hello, we have a problem with the eval board. We use Win7, USB driver is installed, device manager reports ADE7880 Evaluation Board (COM6) under Ports (COM & LPT), USB normally registers within the PC but communication by using ADE7880_eval_software.exe is not possible. If I hit Find COM port I always get XXXXX. If I explicitly select COM6 (which is listed) in the red box, nothing happens either. We tried 2 different notebooks (one with Win7 the other Win8.1, without success).
