You may be right. Some people reported that they couldn't setup
lirc_mceusb2 to wake their system, I figured that that's probably the only
piece missing. It's possible that it wasn't necessary, but it definitely
didn't hurt - I have a Home Theatre box using the driver with this patch. I
spent some time trying to make mceusb2 to wakeup the box, when I did this,
it started working, but, on the other hand, I changed a few other things at
the same time too.
