Mythbuntu comes with lirc 0.8.7, but I'm wondering if its been patched for the devinput stuff?   The Mythtv devinput wiki page seems to say *buntu should be ok.

The 'echo lirc' business is only for raw IR receivers, when you want to do the
raw IR decode in userspace. The problem manifests as both lirc userspace and
the kernel decoding the same IR signal and passing along a resulting key (either
an lirc keypress or a native linux input layer keypress). That's not what's
going on in your case though, since this is not raw IR hardware. I don't have an
answer for why you're seeing double keypresses here. What does ir-keytable run
without any parameters say?
