Thanks to you both for your answer. It wasn't clear to me that usb
receivers for remotes aren't actually the same USB/IrDA dongles. Those
IrDA dongles aren't supported by LIRC, as its FAQ says. But LIRC does
support USB receivers (http://lirc.org/html/table.html#@hw-irda), MCE
being one of them.
I'll just have to buy that kind of dongle errr... usb receiver ;-)
