I have a USB cable with wires that have these colors:

  • white
  • light-grey
  • blue
  • green

I need to attach it to a USB cable with these colors:

  • red
  • black
  • green
  • white

What is the combination?

  • you don't have another end of secondary cable so you can't get pinout out from connector?

  • This is like the TV shows where somebody defuses a bomb by clipping certain color wires (because bomb makers always consult the bomb-makers' color code reference manual, and anyone else can just look up what standard colors they used). If standard colors have been defined for a cable and you find a cable that doesn't match the standard, I wouldn't trust the colors.

This page on USBMan® seems to have the information you require, but the first set of colours do not make up a set of the four different wires, you seem to be missing at least a ground.

When there are non-standard colours floating about I would be very wary of connecting them up without finding out from the manufacturer what colour they are using for what.

  • Colour: RED, ORANGE -> Connects to: POWER, VCC, SVCC, +5V
  • Colour: WHITE, YELLOW -> Connects to: P-, DATA-, SBD-
  • Colour: GREEN, GREY -> Connects to: P+, DATA+, SBD+
  • Colour: BLACK, BLUE, BROWN -> Connects to: GROUND, GRND, GND

  • Now I made some mistakes in wiring wrongly. Then I attached my xbox controller s, and I wanted to know if I can broke it if I mix the wires?

There is no "always right" answer. They have to be checked. If you don't know what a multimeter is, you probably need help from someone more knowledgeable.
