IrDA is a specific type of IR hardware. Unlike IR remotes, it uses a
fundamental frequency that does not allow it to travel reliably over
more than about a meter. That's why it's generally used for things
like sending data from a laptop to a printer that is only a foot or
From my brief look at the USB-IR-Boy page, it doesn't look like it is
IrDA at all, which is why it can work with LIRC. It seems to support
the same IR protocols understood by LIRC.
