    I, too, believe that there are no free "development or
    educational use" VIDs set aside by the USBIF.

    ... or with any VID/PID combination that happens to be included
    with the default Windows installation.  Do a search on your
    computer for *.ini files containing the text "VID" and you'll see
    that the default Windows installation contains support for
    HUNDREDS of devices.  If you pick an arbitrary VID, it must not
    conflict with ANY of those.

    John Hyde, author of "USB Design By Example", gives permission
    in his book for readers to use his own VID during development of
    their products.  Since no one but John can sell devices which
    use his VID -- and he's not in the business of selling USB
    devices --  the devices in your lab are guaranteed not to
    conflict with any others if you use his VID.

    Presumably, John's generous offer applies only to purchasers of
    his book: "USB Design By Example", published by Intel Press,
    ISBN 0-9702846-5-9.
