    I have a problem with matching the colors of the wires to the USB type A plug.
    Here they are (non-standard): red, blue, yellow and white.

    Oh yeah, but it's red, blue, yellow and white. Is this a standard or is the manufacturer able to give such a cable somehow and connect these cables? I turned it on, checked it and it came out:

    Red V
    White D-
    Yellow D +
    Blue GND

    They obviously don't care about the colors anyway, the rest is correct.
    And with yellow is green and blue is black is another story.

    I have a similar problem, I have a track for the motherboard on USB and there are pins, but there is no plug, I do not know how to arrange them because I do not write anything on the colored wires.
    I have the colors: 2xblack, white, red, orange, yellow, green, brown, blue

    can anyone help?

    Gifter - Black, White, Red and Green - you had previously given ..
    As for the other colors - it's the best meter to hand, a diagram / list of the connector layout in the usb socket (even from Wiki) and checking the transitions (although I would check all the cables).

    I guess I pulled them out in that order

    up and down
    yellow- orange
    red- green
    brown - blue
    violet- black

    Could it be like that? because I'm afraid that now, when I hook it up, I'll take it out :( (

    As I wrote before: the best meter to hand, check with the description of the pins / signals (even Wikipedia) - unfortunately there is a lot of freedom in the colors ...

    Hello. And I have this question because I have 5 black, red, white and green wires in the USB cable. One black is ground and one is connected to the housing, but in addition to the black one, it looks like white is also connected to the housing and my question is whether if I plug something in this way (white is the signal wire), I will not damage the device.

    A colleague visited Wikipedia or THIS side? - there are usb connections written there (with the indication of the usually used colors) ..
    Ps
    I doubt that "White" is connected to the casing, it looks like the "usual" color scheme ... But it's best to check with a meter ...

    Hello ;)
    I have a problem with the connection of 2 USB cables, namely my mouse broke (the cables broke at the USB plug). I decided to take the plug from a different wire and solder it to the mouse. And here there was a small problem, namely the mouse cable has 4 color conductors:

    RED
    DARK BLUE
    GREEN
    and COLORLESS (copper color)

    and the USB extension cable has color wires:

    Red
    black
    green
    White
    and one with no isolation around the others.

    is it possible to somehow combine it?

    I have already soldered like this:
    red - RED
    green - GREEN
    black - DARK BLUE
    white - COLORLESS
    and the one without insulation I left it nowhere without soldering it, and after connecting to the computer, a message popped up saying that the USB device was not recognized.

    Please help :) if nothing can be done, there is nothing else for me to do than go to the store for a new mouse :)

    Greetings !

    1. Maybe the mouse did not stand the test of time, and neither did the cable.

    2. Maybe this mouse is some noname made by a color blind person with small Chinese hands and the colors do not match the specifications. It remains to measure the cut-off plug - you will find out which wire is responsible for which pin. You will do the same with the new cable. If it doesn't work, something has burnt.

    Personally, I bet on 1.

    hmm, I can not measure this plug with the mouse because it got fucked up at the very end and even a millimeter of the wire does not stick out of it and I do not know where what color was connected; (

    Maybe something is described on the mouse's PCB?

    he writes on the disc:
    with the green wire - R7
    at the red wire - R6
    with a colorless (copper) wire - C9
    for dark blue - C7

Topic summary

The discussion revolves around the non-standard color coding of USB Type A plug wires, specifically red, blue, yellow, and white. Users share their experiences and solutions for matching these colors to the correct USB signals. The standard color arrangement typically includes red for VBUS (+5V), white for D-, green for D+, and black for GND. However, users report variations, with some identifying red as V, white as D-, yellow as D+, and blue as GND. The conversation highlights the inconsistency in wire color coding among manufacturers and emphasizes the importance of using a multimeter to verify connections. Additional queries about other wire color combinations and troubleshooting USB connections are also addressed.
