Derek - Thanks for the help.  I was trying to compile manually, but I took
your advice and went the dkms route.  It compiles fine, and when I
blacklist mceusb as mentioned, lirc_mod_mce loads fine, too, as shown in
dmesg.  Unfortunately, irw shows nothing, and I'm grasping at straws.  I
am using the default lirc.conf for the mceusb remote.  I also made the
REMOTE_MODULES="lirc_mod_mce" change to /etc/sysconfig/lirc and tried with
and without the flag, both to no avail.  Lircd starts at bootup as usual
and can be restarted without any errors.  One thing I have noticed is that
mceusb will create a /sys/class/rc0 directory whereas lirc_mod_mce will
not. I hate to be the guy to post to the list saying, "Please Help"
without any concrete info, but I don't know where else to check or if
there's a log to look at.  Are there any other configurations that need to
be modified that you know of?  Does the "default" lirc driver have to be
explicitly defined somewhere?  Thanks for your time.
