Thanks PAT,
the problem is that I am a normal “deadly guy”, just a simple MAC user, not sure I understand what you teaching me :-)
Can you please, line by line explain ? Also, will it may work as the upgrade Yosemite ? is it of temporary nature or for ever ?

I too went from Lion to Yosemite on my 2011 Macbook Pro. Biggest mistake I have made with any computer ever. I do not have an answer for you. When anybody finds an answer, it deserves a page of its own on Miklor.com. I have tried everything, I though I had it with this technique, it seemed to work for a while and then it just stopped working as well. But you can try it, good luck and let us know how it works for you:
Here is what I found. The driver is the issue with Yosemite. The built-in FTDI driver prevents the osx-pl2303 driver from loading. The fix (not for the faint of heart) is to do some black magic at the command line.
In Terminal, enter:
sudo nvram boot-args="kext-dev-mode=1" This allows other (unsigned) drivers to load. The driver that works for me is the Lion driver from miklor.com http://miklor.com/.
Then manually load the driver (first time only, it will load automatically after that) with this command in Terminal:
sudo kextload /System/Library/Extensions/osx-pl2303.kext This creates the device cu.PL2303-000012FD, be sure that is what you select in the CHIRP Radio dialog in the Port drop-down. Again in the Terminal, do "cd /dev", and then "ls" (without the quotes) to see that the cu.PL2303-000012FD driver is actually loaded.
