* 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 ;-)
