Recently a new type of USB dongle from SigmaTel has appeared on the market 
which is _not_ compliant with the IrDA-USB specification, and therefore 
doesn't work with this driver. On the other hand, SigmaTel has made available 
the full technical specification  , so writing a driver for it is possible.

BUT Vendor says than this dongle is linux-compatible:

VFIR/IR: STIR4210/4220/4116
USB 2.0 Hi-Speed to IrDA Bridge
...
* Supports MAC OS, Linux, WinME, Win2000, Win XP and later Windows OSs

So I haven't chance to get a valid module for SigmaTel USB dongle?
