Same device, but they changed at least part of the protocol.

Further down in that thread, someone got it to work and posted the
patches, but I'm not having any luck with them.

But since you've at least got the previous version working
successfully, perhaps you can help me. I think the part I'm stuck on
is getting the lirc part working right. My understanding is that after
you get lirc patched, built and installed, and you modprobe the
lirc_imon device, that you should be able to at least use the IR part
of it. Do you know if that's correct? Is there any other modules that
need loading or settings that need to be done? If I try to run
irrecord, it aborts with:

irrecord: could not open /dev/lirc

That makes me think somehow the lirc_imon module isn't loading
properly (though it generates no errors in the logs). The /dev/lirc
device is created by the installer, but it's not there after reboot.
It's getting removed by udev. But even when it's there before
rebooting, its still not working. Did you have to setup any special
udev rule to make sure it gets recreated? I've tried creating one on
my own, but so far it hasn't worked.

ATTRS{idVendor}=="15c2", ATTRS{idProduct}=="0038", SYMLINK+="lirc"

That successfully creates a /dev/lirc on reboot, but it appears to be
the wrong device, because when I run irrecord, I get

irrecord: could not get hardware features
irrecord: this device driver does not support the new LIRC interface
irrecord: major number of /dev/lirc is 13
irrecord: LIRC major number is 61
irrecord: check if /dev/lirc is a LIRC device


I checked, and /dev/lirc was actually pointing to /dev/input/event1.
There are other things under /dev/input, such as event0 through
event4, a  few mouse options, and some by-path and by-id entries. I
tried pointing at all of them, but they all give the same complaint.


Perhaps this is all a side issue from getting the LCD working, but I'm
just suspecting that the LCD is failing for the same reason lirc
is....though I have no idea what that reason may be.
