Kind of important information, yes. Answer: not sure. I can see it
receiving something but none of the keys I pressed caused any reaction

When I try to enable the nec protocol I get this:
# ir-keytable -d /dev/input/event15 -p nec -t -r
Invalid protocols selected
Couldn't change the IR protocols
Hopefully all this stumbling in the dark is somewhat informative...
