If you are not 100% sure of the cable, try connecting to some other (any other) device to verify the cable supports communication, and if successful, try the Prime again.

I have tried several cables... tomorrow I am going to try with windows PC. If it will not work the problem will be the calculator itself. If I reset HP Prime is there a possibility to solve my problem?
