Re: Ironically the FTDI clones actually work better than the originals
I sympathise with FTDI regarding "clones", but you're right about their "bit bang" mode and reluctance to admit it. The erratum (version 1.0) which you mention is dated November 2010, but they admitted the fault in an email to us in November 2008: The uneven pulse width is due to a flaw in the clock synchronization (sic) between the usb and output stage. Knowing that the device didn't work as described would have saved my designing to use it in that way and several more hours investigation to discover that it was their fault, not mine.
