lirc_options.conf.  In my Fedora system, it's located at
/etc/lirc/lirc_options.conf

It could be that your driver line says "driver = default" (or possibly
something else?) instead of "driver = devinput".  If that's the case, lircd
won't listen to devinput.

Test with irw as well.  Also make sure that the name of your remote
(mceusb, myremote or similar) is correct.  In my system, the remote
configuration files are in /etc/lirc/lircd.conf.d  I thought there was a
reference to it in ~/.lircrc (or wherever your file is) but I don't see it
there.  LIRC confuses me a lot and I haven't tweaked my setttings in over a
year.  Still, that might be important also.

I may be wrong but it's worth a try.  A few upgrades ago, that driver
setting was flipped on me (in the other direction).  It could be that a
package upgrade changed that setting for you.

Hopefully a LIRC guru will chime in and give your some proper help.
