The Xbox DVD Movie Playback Kit is a USB dongle with an IR remote for the Original Xbox. Historically it has been supported by the out-of-tree lirc_xbox driver, but this one has fallen out of favour and was just dropped from popular Kodi (formerly XBMC) distributions. This driver is heavily based on the ati_remote driver where all the boilerplate was taken from - I was mostly just removing code.
