libftdxx is a closed source library from the manufacturer that has *windows* 
equivalent calls; it's used to make porting windows programs to other platforms 
a little easier.

It is far better to follow the advice below and use the open source support 
already in the kernel, rather than use a closed source lib to provide windows 
functions (that your linux programs can't even use).

If you are writing new software under linux, use the POSIX serial port API 
calls.  If you are porting a windows program, you'll have a little more work to 
do, but when you are done you can use any serial USB device supported by linux 
and not be restricted to one vendor or one chipset.
