Thank you very much for your response!
I have same problem with CCStudio ver.10. same type of error, I belive EZ-FET is the problem!
With win7 everything is ok. but in win 10 nothing work; I install latest driver from TI, I change the port, name it.. but nothing work , I believe, win10 don't work with Exp430G2 older version(Rev1.5) anymore ; I have only a supposition!
Thank You again!
