    Subject[PATCH] USB: Gadget: g_multi: added INF file for gadget with multiple configurations
    When a mutlifunctional gadget has more than 1 configuration, Windows does not
    use its generic driver for multifunctional USB devices.

    This commit adds an INF file that will load the required Windows driver
    as well as a short description in gadget_multi.txt

    Signed-off-by: Dries Van Puymbroeck <>
    I based the INF file on linux.inf. I tested it and it works, but perhaps
    the style could be improved. Comments/suggestions welcome!
