Say Y here if you want to build support for the SigmaTel STIr4200
USB IrDA FIR bridge device driver.
USB bridge based on the SigmaTel STIr4200 don't conform to the
IrDA-USB device class specification, and therefore need their
own specific driver. Those dongles support SIR and FIR (4Mbps)
speeds.
To compile it as a module, choose M here: the module will be called
stir4200.
