Details:

I am using AVRDUDE 6.3 on Windows 10.
When i try to program a AVR processor using the FTDI Bitbang methode, windows
reports missing FTDI drivers.
All the driver files are present, but to get this working AVRDUDE must be
recompiled, with the FTDI Direct D2xx drivers.
I don't have the knowledge how to do this.

As an alternative you can use the normal serial bitbang driver, but this is
very slow and, only suitable to program a small program (Bootloader).

I also found an older patched version that will work, but this is not a good
solution, because it doesn't support new devices.
