    Hi all,

    I want to control a breadboard-based circuit via USB,
    but I am wondering about the prospects for doing that.

    1. Where do I find USB devices will give me
    digital outputs, e.g. 8 lines and a few inputs?

    2. I'm using Windows, which is no RTOS.
    What kind of frequency could I achieve if,
    for instance, I controlled the USB device using
    a C++ program?

    FTDI do a little module UM245R for about £11 / $20
    It has USB at one end and 8 data bits in/out at the other.
    Looks like a com port to Windows.
