Hi,

actually I wrote an updated driver for this NSC chip, but my latest
developments are some time ago... Meanwhile the IrDA module maintainer
sent me an update of my update; maybe support improved. My latest status
was a working FIR driver, but I did not make it working faster than 115kB/s
with my IrDA printer. Might be a problem of interoperability between the
devices but more likely the driver is still not working correctly.
