Apple iPod shuffle secret revealed: inspection shows five extra contacts on USB plug

“Close inspection of the [Apple iPod shuffle’s] USB plug reveals that there is something going on here… A normal USB plug has 4 contacts (5 counting the shield), but this one seems to have 5 extra,” Chipmunk International reports on a page they have posted that shows an iPod shuffle’s dissection. “There seems so be a secret extra something built into the iPod shuffle that can interface via the extra contacts hidden in the USB plug… This iPod shuffle is brand new and has not been plugged into anything since leaving the factory. Yet the middle of the 5 extra contacts has clearly been used. So whatever it is, the manufacturer is using the middle pin in the factory.”

  1. After checking my USB inputs (female connectors) none of them have a middle pin that would connect to this mysterious fifth pin in the shuffle anyway. Maybe it’s for a Grifin iLCDScreen, or some mysterious connection yet to be reveiled.

  2. I know, I know!!!! Steve has inserted a secret harware/spyware that will call Apple everytime you plug in the shuffle and tell him what you have been listening to and how many time the shuffle has been jolted, allowing him to tell if you have been doing the horizontal bop while listening to your fav tunes, thus allowing Apple to target the appropriate market for the new (and yet unannounced) iPod iNteruptus. The new device will play your favorite love tunes throughout the deed until the point of, well, climax, then it will shuffle to a Dave Matthews tune and you will immediately loose the urge. Brilliant!!!!

    iSteve for Surgeon General.

    Magic word = “planning”, get it?

  3. The fifth pin is probably a testing interface to an LCD to check the unit prior to shipping. The others are for possible 3rd party divices yet to be produced (iRadio, memory expansion, vehicle ports, etc)…
