You've got infrared light coming from somewhere in the room.

Pretty sure its the mce device.

That's a hardware feature. When it sees infrared, it lights up.

Dunno what's going wrong there. Possibly too much interference.

You have lirc_mceusb's debug param set. Unset it. But your real problem is all the stray infrared that its picking up.

There might be something slightly off with the config, but its hard to tell at the moment.

Figure out the source of infrared light driving the receiver crazy, then try testing some more w/the remote.
