/*
 * Puts a Hitachi-LG Xbox 360 DVD drive into modeB.
 * In modeB, the drive responds to standard ATAPI
 * commands that it otherwise wouldn't (for example:
 * Read(12), Inquiry, Mode Sense(10)). ModeB also
 * changes, among other things, the behaviour of the
 * drive's eject input and tray_status output.
