[mythtv-users] Harmony 550

I have a serial IRman (One of the older ones).

If i remember correctly I needed libirman or something for lirc to
use, and then the irman driver for lirc. I imagine it would still be
the same as I suspect the USB irman is either using a serial->usb
bridge chip, or is programmed to act as a USB serial device.

if you run irw at the command prompt it will dump any ir codes coming
through, good test util.

Something else of note, I noticed that with my 550 i usually get two
codes per press. So in your rc's if your having issues with stuff
happening twice, set Repeat to 1 or higher. Myth seemed fine, but I
had to tweak my mplayerrc.
