Media Center - IR hardware

> Has anyone had luck with Media Center finding their IR hardware? I have a
> USB-UIRT and it reports that it can't find it. So, I can only tune to
> channel 3 (I have a set top box), and then use the remote from the box to
> tune. Vista found the driver for it and installed it. I also have the
> driver myself. I've tried it both ways.
