    USB color coding question


    Can someone tell me what the color code is for the "key" wire for a usb connector? For example.......

    J1

    Pin #
    1= +5v(red)
    2= P0-(white)
    3= P0+(green)
    4= GND(black)
    5= N/a

    J2

    1= +5v(red)
    2= P0-(white)
    3= P0+(green)
    4= GND(black)
    5= Key(this is the one I don't know what the color code is)

    I think you'll find that "key" means that you use that to tell you which way round the plug/socket goes.

    When you see the word KEY, think of something that locks something else in position, rather than something you type with.


    My mobo has a 10pin in line header (ie. there are two rows of 5 pins). The colour and meaning are as you have stated. There is nothing (ie. empty) at the end of the first row, and a spare "key" pin at the end of the second.

    My USB works just fine.

    have fun

    Use Suse 10.1 and occasionally play with Kubuntu
    Also have Windows 98SE and BeOS
