    +/*
    + * Belkin is selling a dongle called the SmartBeam.
    + * In fact, there is two hardware version of this dongle, of course with
    + * the same name and looking the exactly same (grrr...).
    + * I guess that I've got the old one, because inside I don't have
    + * a jumper for IrDA/ASK...
    + *
    + * As far as I can make it from info on their web site, the old dongle
    + * support only 9600 b/s, which make our life much simpler as far as
    + * the driver is concerned, but you might not like it very much ;-)
    + * The new SmartBeam does 115 kb/s, and I've not tested it...
    + *
    + * Belkin claim that the correct driver for the old dongle (in Windows)
    + * is the generic Parallax 9500a driver, but the Linux LiteLink driver
    + * fails for me (probably because Linux-IrDA doesn't rate fallback),
    + * so I created this really dumb driver...
    + *
    + * In fact, this driver doesn't do much. The only thing it does is to
    + * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
    + * driver is called "old_belkin" so that when the new SmartBeam is supported
    + * its driver can be called "belkin" instead of "new_belkin".
    + *
    + * Note : this driver was written without any info/help from Belkin,
    + * so a lot of info here might be totally wrong. Blame me ;-)
