    I believe the Flex will only recognize FTDI chipset USB/Serial (or bit- parallel) devices.

    Thank you Ted, I have been beating myself up over my lack of understanding of what FTDI was. I was thinking that it was something in the cable itself as far as controlling the relay board was concerned. Your use of the word "chipset" put me in the right direction. I didnt think to search FTDI - daaaa . Now i understand. thank you very much. I had my head stuck in a special cable configuration. Again Thank you.
