Config all looks perfect.

Hm. Can you isolate exactly which keys are generating these? The issue
here is that these scancodes aren't mapped to any keycodes in the
driver, as I/we haven't ever seen them before.

Note no 'unknown keypress' after this one, as that scancode maps to KEY_DOWN.

Yes. If we fail to find a scancode, then we are unable to send a
keycode, and lircd in devinput mode relies upon keycodes.

Not a hal problem. We just need to add some more scancode->keycode
mappings to the driver. If you can figure out which button each of
those unknown scancodes maps to, I can get them added to the driver.
It *should* be possible to upload new mappings into the driver using
ir-keytable from v4l-utils, but I've been having issues with it myself
lately...
