Schematic PDF for the audio and USB daughterboard used with the Sony MBX-165 platform in its MS90 version. It covers the small sub-board circuitry rather than the main logic board. That makes it handy when ports are dead, the headphone jack or speakers fail, or you need to trace the connector that links to the mainboard. Use it to check USB power switches, fuses and codec lines, and to measure continuity across the interconnect cable. Match the board revision before trusting individual component values.
