    What does the green (D+) and white (D-) do in a a power cable? Only Red (+) and black (-) are live... Why you connect the green to the switch? What's the purpose?
    Instructables, I am really trying very hard to be nice, here...

    Instructables should remove this nonsense article...
    It is miss leading and insult for the rest of the people that write useful things here.

    Hi,

    I was just wondering why does D+ need to be switched as well. Only switching ID to ground will not work?

    I wonder if it would be possible to do this with a small timer circuit instead of a manual switch....

    In short:

    1. Make cable as per schematic in Step 4: Wiring.

    2. Switch to 'Charge'.

    3. Connect everything: Phone charges.

    4. Switch to 'OTG': USB device is connected to phone, and phone is still charging.

    (I haven't made it yet though.)

    I've been needing this for a project! Thanks man :D
