Take note the latest release version of libftdi 0.x is 0.20.
I've put the Windows binary download here.

That directory is for 64bit dll. You need to put the dll in
C:/Windows/SysWow64/

So you are using 32bit Python under 64bit Windows, in
that case, this is one way to get Python to work with
libftdi dll. The other way is to put it to the syswow64 directory
and in that case, it is usable by all 32bit applications.
