Not sure if there's a menu item you can select for that thing or not.
But basically, its a receiver that ties into the linux kernel's input
subsystem, and creates a device /dev/input/eventX for the remote, and
delivers keypresses to the system as if they were keyboard keys a la a
multimedia keyboard, more or less. You can use such devices with lirc
by telling lircd to use the devinput userspace driver instead of the
default driver (lirc kernel driver), and for device, pointing lircd at
/dev/input/eventX for the device (or more appropriately, as X may
change, at the symlink to /dev/input/eventX that should land in
/dev/input/by-id/<some-string-that-identifies-your-receiver>).

Separate issues. Definitely repair your db, but yeah, its not related.

See above. :) There is no /dev/lirc0 for this device type.
