USB color coding question

[Richard_The_Lionhearted]

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
