    Hello,

    the problem is, that most (all?) USB-to-LPT adapters don't emulate legacy LPT port, only support printer device. Ponyprog serial ISP adapter can be expected to work with common USB-to-RS232 adapters, but probably rather slow. For optimal performance, FTDI FT2232 could be turned into an ISP programmer using the bit-bang protocol. This would require writing a programming driver, either standalone or as Ponyprog extension.

    FTDI has example code for SPI or JTAG interface, it's rather easy to my opinion.

    Regards,
    Frank

    I think, http://www.sunrom.com has a solution for it and they sell boards also for the same. They even sell bare PCBs and firmware programmed controller chip for that board.
