I've done some tidying up of pylibftdi, fixing a few bugs, refactored the pylibftdi package to contain several modules instead of everything dumped in a __init__.py file, and generally made it a bit cleaner. It even has docstrings for most things now, and a test or two!
pylibftdi is a simple interface to libftdi, which in turn allows accessing FTDI's range of USB parallel and serial chips. See here for more details, but very briefly, serial access is provided by a file-like (read/write) interface with a baudrate property, and parallel access is provided by a pair of properties - direction (data direction register) and port (data IO register).
I haven't yet added any more examples, hopefully I'll get round to that in the next week or so. I have been using it as a MIDI interface though, which is fun - I'll get an appropriate example of that out in the next version, together with some diagrams / photos etc.
