Morning Roberto,
Thank you because I saw TERMINAL and copied theses in it : sudo cp -R TIVCPSerial.kext and so on.After rebooting when I connect the tusb3410,this message appears: the system extension can't be use.the extension < SYSTEM/LIBRARY/EXTENSION/TIVCPSerial.kext doesn't corectly installed.
Please can you help again.
Regards
BEN.
