OpenGD77

Thank you for your answer, I have read perhaps all topics with this issue and I tried everything. I dont know why, but now its working. The last system changes i tried: - uninstall all GD77 (original, open GD77, comunity) software and drivers - install and switch to US english language on Windows - ...

Does anyone have any new information on this issue?

I tried it on two machines with the same result. CPS always says "Device not found" during Read / Write and "Failed to open comm port" via OpenGD77 support.
