    Hi friends,

    Does anyone know what USB 2.0 symbol represents?? You know, the symbol
    looks like a fork with 3 legs: 1.Circle on the left, 2.Arrow at the
    middle, 3.Square on the right. What do they represent individually. I
    guess they would mean something like data, supply voltage and ground.
    But which represents which??

    Interesting question, right?!

    Any comment would be very appreciated.

    Way too deep I think.

    It's an symbol for end-users to identify with.

    It iconifies a bus with different devices connected to it. For what it's
    worth the symbol you refer to is USB 1.1, a USB 2 trident symbol should have
    a '+' sign next to the circle.

    Aside from being the USB logo/identifier, it has no meaning - It's a
    made-up graphic that's reasonably visually-appealing, even when
    displayed as a molded-in impression on a cable, and is distinctive
    enough to stick in a consumer's mind. Also, if it's a 2.0 item, it ought
    to have the little "+" next to (stops and thinks - Is it the arrow, or
    the circle? And none of mine are easily reachable/visible at the
    moment... Grrr...) one of the legs, where the 1.1 version has no "+".

    That's all it's supposed to be, and all the <TM> owners license it to be
    used for. (yes, you have to buy a license and meet their standards
    before you can paint, draw, stamp, print, mold, or otherwise use the
    symbol on something that's for sale)

    You know, the symbol
    None represents any - See above. If there's any "public, secret,
    official, or otherwise" meaning beyond "Something with this mark can
    have something else with this mark plugged into it, or perhaps it can be
    plugged into the other something - or both", it must be pretty obscure,
    since yours is the first mention of any such thing I've encountered
    since USB jumped into the public eye with the debut of the original iMac.
    I guess... If you're "easily interested"... :)

    Seriously, though, I'd be more inclined to say you're thinking *WAY* too
    hard about something that doesn't merit much, if anything, more than
    about 5 seconds of consideration.
