What Each Colored Wire Inside a USB Cord Means

Hi Mark

My nephew is a whiz with computers. He takes care of all of the issues I have with mine. He taught me about USB cords although I admit I really know very little about them. I just know when I need them and where to plug them. This is a topic that many will find very interesting as you have a number of hubs on it and you elaborate. Thanks for sharing. Sending angels to you :) ps

my USB has three wires and i want to know that i want to make a lamp using USB cable and i am conffused in which wire that the current flows

sir please send the answer related to my problem in my E- mail address my Email address is MALUKSINGH0786@gmail.com

im trying to make usb Y with two male ends for additional power supply, should i just connect the other male with its + and - wire and the data wires as dead?

I am not sure if this is the right forum,but I will try anyway.

I would like to connect an AV plug to one end of the USB, but I don't know how .My wires are BLK RED WHITE and GREEN.

Thanks

I have a USB cord but the colors inside are white, yellow, green, and blue. How do I tell what they are.

I'm curious about the iphone ;) How is it there? I checked it out myself but am yet to understand what all the wires are for... There are like 8 wires with different sizes, I have no clue what is what and can also not find a site so far that could help me. Whould very much appreciate if you could help thanks.

Hi Mark, the wire colors of my blackwidow keyboard are white, yellow, pink and purple. Which of it connects to a certain color in a standard usb plug? Thanks in advance :)

im cutting out a wire from my mouse. turns out it's got red, green, white and blue. i wonder if this blue wire works like that of the black one in the first example. cheers!

Hi Mark, thanks for the response.

I' ve made the rewiring but it just says "usb device not recognized". Another thing is, There is a current flowing through the keyboard but it doesn't light up. I also did some trial and error one the wirings but none worked. What do you think is going on?

Hi mark please help me in my work that I have a webcam which is not in the usb mode so I just want to cut the wire of the webcam and connect to the webcam, the webcam is integrated with a microphone too, and which has a color code of red,yellow,white and black. from the cam the wire came out in a single and about 3 inch from the cam the wire wire is divided into three phases of three connector like that of the video, audio output cable of the DVD player the color of the wire are yellow, red and white. I think the black color is divided and flow with each of the three color, So I would like to connect the webcam with a usb which has a color code of red, green,black and white, will it be able to function the webcam. Will it need a driver for my PC but I don't have any driver. please help me to convert it.....

Hoping your good response.

Good day Mark. I have an ASUS Eee tf201 tranformer tablet that uses a USB for its power source. The power supply states that it is a switching power source of 5v 2amp - 15 volt 1.2 amp. I want to use a portable battery source, but I am told it will not supply 15 v from the USB. I would like to use this portable power's 14 to 16 ( adjustable power) port, but it is round, not a USB. Can I just use a suitable round connector and solder + & - power to a female USB. eliminating the data wires?

hi, I have already tried to use a standard USB 2 amp portable power source, and it did not seem to work ( charging light did not appear). I purchased an extra power supply from a vendor (not ASUS) and it says 15 v 1500 milliamp, so I figure the tablet does need 15 volt. if I try to plug into a computer it does not charge, nor does it charge on any USB port except the one that came with the ASUS tablet. i talked to a portable power vendor, and he is changing the power from a 12volt serial to 15 volt USB for me. I can also use this same power supply for my Toshiba as it has 20 volt adjustable serial port as well as the USB 5v and 15 v ports. Being in China has its advantages as the vendor is making the USB port for me; no extra charge.

Nice work here, Mark. I've never really inspected the wires inside any of my USB cords but was delighted to find this source of expertise on the subject. Who knows when I might need it?

After all, I've been learning more things in the last few years than I did fifty years ago in school.

Voted Up and More.

Hi Mark, any thoughts on my white, red, purple and orange configuration. No example online seems to show this. Micro USB cable. I would love to know which is which.

Hello,

I have blue, gray, white and green - would you please advise me on which are the power/data wires?

Thank you! :)

Thanks for the reply!

The green and blue wires seem to be insultaed by fuzzy/shiny material that feels like fabric - they're on the leftmost and rightmost sides of my cable which is flat. The white and gray cables, in between the green and blue, are very tiny and insulated with rubber.

I've tried testing both green/blue and white/gray cables a LED (output voltage accounted for) with no luck.

Appreciate the help! :)

Please indicate what is the use of "usb cable AM to -A ( RoH8 ) " Is it to link two computers for transfer data ?

Uuuhhh i want to rewire an internal card reader I found to a usb cable, but the cable has: black,red,green,blue,orange. :P Is this not possible, or am I missing something?? :/

This is a very informative hub. I don't know anything about computer inner parts because i am not a computer savvy so it is my first time to know about the USB wires. You explained them very well just like a good teacher and I'm sure anyone who will read it will understand what you have explained. Thank you for sharing.

Thanks Mark. I do write fast when I find time to write. Keep hubbing because your hubs are very helpful.

Hi can anyone help. I purchased a smart TV and my Wii will not hook up to it. The Wii has 3 color coded wires, white, red and yellow however the tv has only two entries with a smaller imput like a headphone. I purchased a wire from a store and they told me that if I buy a coupling to join my wii wires to the new one I purchased it would work. The new one I purchases has three color coded wires that are Red Green and blue and at the other end is one wire that looks just like a headphone wire and it did fit into the tv however I am not sure how to join the new ones to the WII because the colors are different. I did manage to get it up on the tv screen however the picture is really bad and coming and going. Can anyone help or have any advise on how I can get this to work. The TV is a LG 55 inch Smart TV and the Wii is an older model thanks

Hi Mark, I have a broken Ipad Mini Lightning cable wire, I've checked it inside and I could see a black, white, green and red wires. can you help me on how to connect it to the main board of the plug please?? thanks

I have a fun one! :)

I have an apple lightning to USB cable. The usb end is bad. I want to try to splice the cable with a USB cable I have sitting around.

The lightning cable has pink, white, green and then 3 pieces of unshielded cable.

The USB cable I want to use has the traditional black, white, red, green.

So, I'm wondering what to do with the black wire in the USB repair cable?

Are the 3 unshielded wires in the lightning cable a ground and could I just put those together and connect to the black wire in my USB repair cable?

Hi Mark,

I have found that in the case of the wires Black, Red, Green, White, the coding is thus:

Black = ground

Red = +Ve

Green = +data

White = -data

where the data wires are the opposite way around to how they are in your pictures.

Not sure if this is just in some cases or not - perhaps further research will prove to be useful.

I spliced the red, green and white wires in the USB cable to the red, green and white wires in the lightning cable.

So I have the black wire left in my USB cable

But...

The lightning cable doesn't have a black wire. But there are 3 thin unshielded wires. Are they ground wires? Can I put them together and splice them to the black wire in the USB cable?

Hello, I am making a solar panel phone charger and I have 2 wires (the red + and black -) wires that need to be attached to my phone charger that I have cut. However, I noticed that there are 4 wires. I just attached the red to the red and black to the black because I assumed that those are the ones that help carry the electricity. What do I with the green and white data wires. Do data wire carry electricity that help charge things? By not connecting them to anything is the phone not receiving all of the electricity? Also I don'r really understand what ground wire means; does it just mean the negative end of the wire that carries electricity? Thank you

My "other" proplem

Is that after 2-3 months of modered use, my caple starts charging slower and slower... soon yes i end up with

(Not detected - Detected - Not detected -Detected and so on) and always ends with Not detected

I think the proplem is just whering down the copper by use.

I think it's cutting corners on prize by manifactural proses..

Maybe they need a better metal or metal mix or maybe use just a little more copper in the tupes... they know chargers and most Usb with mini usb end will move around alot more now day's

*Hope u understood this, dont have time 4 spellcheck now

cheers from Iceland

Hello mark, I'm looking for a temporary solution to my phone charging problem until i get it fixed. It's a Galaxy Note 3 and it seems that one of the pins inside the charging port has been bent/pushed back i think. I can see it near the back of the port when I look. Anyways, it currently charges if i use a wall charger and even charges when plugged into my PC as well as transfers files, but it charges significantly slower than it use to and it will not recognize most external power banks. They charge other phones but nothing happens when plugged into mine and the power banks eventually just turn off because they arent being used.

In short, I'm wondering if I can modify one of my cables by removing a wire or rerouting the wire in order to either fix the external power bank issue or to increase the speed my phone charges back to it's normal speed. 2 questions in 1 but I've searched for days and asked in other places. this hub seems very informed and even if It my problem cannot be fixed, any insight would help alot, and I've already bookmarked this to read other articles. Thanks in advance

(side note - some power banks work on the phone and some do not, even ones from the same brand.)

Hello Mark,

Hello Mark,

Hi is it applicable to charger... my charger has 2ampere the wires are red and black only, but the charging pin is broken so i decided to change to other pin but the pin i was have are 4 color which is red black green and white ... how can i connect it

None of this is right.. Blue is usually ground, not data-, green is always data+ in any color scheme, and white is data-..

The correct scheme if you want to connect these 2 different colored wires together would be this:

Red or orange = 5 V

White or gold = Data−

Green = Data+

Black or blue = Ground

So in other words, orange to red, white to white, green to green and blue to black

Hi Mr Mark.

Hope you're doing well.

I have a small problem. Having read this post I thought you might help me.

I have a laptop table below which are fixed two 5-volt fans that receive power from the USB port in the laptop.

The problem is that the metallic piece of that USB cable that is inserted in the laptop is corroded. So I cut that corroded USB cable metallic piece and tried to attach another one. But I have failed in doing so when though I have connected the right type cords. i-e green with black and red with white and tried to test it with a battery as well. But that didn't work.
