Did some testing on my Creative wall charger after wondering why my MicroPhoto would not charge off of a “standard” car USB charger. Found that mystery pin X carries +3.3 VDC, likely as a trigger for the player to charge if it is not seeing PC USB data on pins 2 and 3. Awaiting parts to try building my own cable for further testing.
