USB interface

I am new to stamps so I am sorry if this is a dumb question.
Can I get a stamp to connect to a PC via the USB port?
I want to send data back to the PC but can I write a program that
allows the stamp to communicate on the USB port?

thank you for your time and have a good day

    I bought my USB to Serial from Parallax. It works like a charm.

    sorry, I think I mis represented what I was trying to do.

    I did not want to buy another product I was trying to use the stamps
    I/O pins to interface with the USB port. a USB to serial adapter is
    not what I am trying to achieve.

    I have been looking at the dlp product but it looked like they used a
    pic controller to do the interface USB245

    Is there a Mac OS X driver for this bad-boy? Is one needed?

    I use a keyspan USB to serial converter on Mac OS X it comes with
    drivers, it really works well.

    Has anyone had any luck geting a basic stamp to ommunicate with a PC,
    or anything else for that matter, over USB? What controller did you
    use. How did you interface it?

    Yes, many people have. The device we've had the most success with (though
    there are others) is made by Bafo. See the link below.

    FTDI chip make two very easy to use solutions for integrating
    USB right in to your projects.

    www.ftdichip.com

    I have some pointers on my web site on how to get these going
    with a Stamp.

    This can be a tough question.
    1. You can very easily buy a USB to serial adapter
    (I like the KeySpan 19W), load the driver, and
    use this to talk to the Stamp's serial port.
    Thus, "it is easy to interface Stamp with USB".

    2. If you want your Stamp to be a 'native' USB
    slave device, an earlier post had a web-site
    which has interface I/C's, along with free
    drivers which make them look, again, like
    Serial Ports, but really high speed ports.
    They have a couple of interfaces out to the
    Stamp (SPI and parallel, I believe).

    3. If you want your Stamp to be a USB 'master',
    and connect USB slave devices to it, I don't
    know of a way to do this. I'm sure there
    are websites having 'Stampish' solutions.

    The point is, if you want a good answer, you
    must specify if you want your Stamp to be a
    'slave' or 'Master', is 232 emulation enough,
    and be aware that some USB driver code is
    needed on the PC even if your Stamp IS a
    'slave'.
