I had already tried that driver, and no cigar, but I will try again for sure.

Is there a hardware solution for this problem?  Is there a different cable I can buy?  I have tried to fix this problem on Windows, Linux, and Mac and I just cant get it to work.

Pat - there was a post on this group last month regarding this and the solution:

===============================================================
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 drivers to load.  The driver that works for me is the Lion driver from miklor.com.
