I have tested it with another FTDI chip that I just bought as well as via a linux VM. All results in the same behaviour.

I have found a FT2232HL which should definitively be a genuine part and it shows nearly exactly the same behaviour as above. Just with fixed 25kHz output clock instead of 77kHz,

Sadly not so much. The signals I get look fine but the number of clock cycles is odd. I am not sure whether some at the beginning or end are missing or whether more clocks are output than should be.
At the moment I am trying to setup an Eclipse project to compile this code myself as the hints in the readme do not seem to work anymore (or I am not competent enough to get them to work ;) )

I also measure the clock frequency at 80KHz, even if the output says 20kHz

Nothing from my side. I sadly never got it working...
