skeptic: the i386 build of the usbuirt.so currently has a bug.. you need to plug an ir dongle in the back, because it doesn't transmit on the on-board ir blasters.
get a xantech 286 double ir emitter (you are supposed to do this anyway), attach the emitters to your gear, and the problem will go away.
Ah, that would explain it. Any idea if/when the bug would be fixed? I don't really need the transmitter at the moment, more of a nice to have.
