Request: mini USB pin layout

Hi I'd like to know whats the USB pin layout on the O2 Atom as my mini USB plug fell off and I'm trying to solder it back to gather.
So far i manage to get it charging again but I cant get data through it.
Also I wonder if anyone can tell me how to make a USB charging cable so that i can plug it into the PC and charge without activesync(without using WM5storage, just plug and charge) or I can charge via car charger(I know this can be done with a special adaptor but I'd like to make my own)
Help is very much appreciated Thx.

well i suppose that no one really know about it so if possible for those who already have thier Atoms opened up, take a high ress pic of the USB plug showing the pins and post it for me.
thx

actually i have a cable(which came with a universal battery pack) that allows me to do what i want but its in a bad shape hence I'd like to make another.

usb is pretty much usb htc's carry audio too but people report that normal miniusb in 1 end and usb in the other works just fine
and any device connected to usb's 5volt and ground get power even if the pc dont see it as a usb device it still provide 5volt and 0.5amps to them
thats how usb cup wamers and plastic dogs humping the usb port works

See here @ Wikipedia for details on pin-outs

Make a Video Out cable from your ear plugs.

If anyone is keen , or if you are like me and have a spare headset from another phone you can use the following diagram and cable colour code to make your own video out cable.
I have used the Raphael cable for this excercise as I like my old Hermes one better.
You will need:
One Red White and Yellow RCA Cable
Step One. Remove pin four from the extUSB plug. *note this can be tricky but is necessary to allow the device to recognise the cable as a TV out cable as opposed to a Headset cable. I used a needle to bend into the middle of the plug and then used a tiny micro screwdriver to bend backwards and forwards until it broke. Be careful not to damage any of the other contacts. Please see post 20 for an easier option that doesnot involve removing pin 4
Step Two. Cut cable as close to mic piece as possible and remove outside cover.
Step Three. Solder the following pairs of cables together using the following codes:
Video positive (Yellow RCA end) --> White pvc coated cable (extUSB end).
Video sheild (Yellow RCA end), --> blue copper cable (extUSB end).
Audio Left (White or Black RCA end) --> green copper cable (extUSB end).
Audio Right (Red RCA end) --> red copper cable (extUSB end).
Audio Sheild ( both Red and White or Black RCA end --> copper cable (extUSB end), * note the copper cable is the sheild wire that surounds all the coloured wires.
The last two colored copper wires
Step Four. wrap electrical tape around the solderd wires so that they do not touch any of the other contacts.
Step Five. Plug in and play.

I am unaware if this works with all devices as I only have a Raphael to test this on. If anyone does find that their device works with this cable let me know and I will post it with this post.
I think the device must have the TV out function cooked into the Rom or maybe there is a registry hack?

This is awesome. I was just going to buy one to. I think this should def be a sticky.

Thanks for sharing this! I I will try to make one from a 3.5mm adapter.

Thanks man, that's very useful

Let me know how that works cause i was going to do the same.

i found a similar post on ppcgeeks a while back. Took me about 30 min to remove the 4th pin...i used a safety pin- someone at ppcgeeks offered that advice. Works like charm. But f you have no patience, buy it on ebay.

Please note that the mini USB must have contacts on the inside of both the bottom and top. the average mini USB sync cable does not have the necessary contacts.

this is such an awsome mod, im going to try this out. lol

i removed the pin 4 as stated in the picture but the cable is not recognized as a TV Out cable and no longer is recognized as a headser, i made sure i didnt damage any other pins besides the number 4.
another thing is that i only want video i dont care about audio does the TP sense that is conected or can i just solder the two wires required to get video?
excelente post BTW
EDIT:
Does the TV out only outputs certain content or can any content can be shown on the TV
i have a 7" monitor in my car and i wanted to use this monitor to display GARMIN as its bigger screen.

im gonna answer myself
any content can be seen on the TV.
yes it does have to be conected to the TV and the TV has to be ON in order to detect the signal.
also make sure the pin is completlly removed all the way to the bottom.
IT WORKS !!!!!!
thanks one again, excellent post.

Aanyone know if this cable works with HTC Touch HD?

sorry, but I am curious on this unanswered question...

Works great! Finally some use for the old, spare headphones and a/v cables I had laying around.
i imagine it would work on all htc devices that support tv out, but that is just a wild guess.

It is work on HTC Touch Cruise (Polaris)???

Hey i found my old vogue headphones,would this also work with the vogue headphones?

This will work with any mini USB plug that has internal contacts on both the bottom and the top (see Step One.JPG in first post). The colour of the wires may vary but I would imagine that there would be a standard colour code for all earplug cables made by HTC, however these may vary between companies.
Hope this helps.

thanks dude. Could it be done with an ordinary mini usb cable?

I tryed this and it did not work for me so I went to Amozon.com and got the Ipod RCA jack didnt cost much at all. Clean look and dont wast the nice HTC ear plugs but I guess you guys are happy with it but now I need new ear plugs...

I didn't use HTC plugs at all, bought Creative ones + 1 pound adaptor and they are way better than stocks, so yes I'm happy about that mode I've done like.. 10 mins ago?
Had some problems with all operation couse it was quite difficult to find right cables on photo that author attached (of course I really appreciate audible_paradigm work, all that mess was about different colors of my cables).
Anyway, it works veeery good and I'm one step closer to get this phone liked
Ps. You don't have to remove 4 pin in usb cable guys, just install one of the .cabs attached in THIS topic - much easier x]
Big thanks!

D.i.y usb otg adapter/cable

Hi,
I made my own usb otg adapter from a plain usb a to micro b adapter. You have to connect pin 4 /which is not connected/ to ground to fire up host mode.
Edit: It is not easy to dismantle a usb connector or adapter and it requires soldering. So I guess anybody with the necessary skills will find the pin on his own. I will not post photos because my solution is far from being pretty.
For everybody else: the nokia USB OTG cable is wired the same way so it is very likely that it will work. (on Hungarian forums I saw references that it works, but I can not guaratee it.)
Tommorow I will go buy one and report.
USB Host mode will allow to connect USB pendrive, mouse, keyboard etc. to the SGS II.

this is very useful for people like me who knows how to solder things, but for the people who have absolutly no Idea what you are talking about, you should add more details/pictures to the OP so the people who doesen't know much about electronics know what you are talking about, and what benefits it brings for them.
I myself will probably make one or more, so I don't have to always take my USB OTG with me all the time.

OTG Cable USB (B) to Micro USB (A) Powered with AAA batteries
As one knows, Samsung has promised a HMI Cable
You noticed it is not only a cable but a box out of which you may plug in an extra power supply.
The obvious reason is if the passive monitor does not furnish 5V, the phone will rapidly be out of power.
Now you know that to obtain video rather than anything less, Pin 4 (sense) and 5 (Ground) of micro USB (male A) must be connected with a 365K resistance.
I suppose the dock Samsung is selling for I9100 (yes, I have it) is grounded at 1000K as it provides audio with remote, and yes, the dock provides power supply via extra micro USB as well.
I come to my point: If I want to access any USB data On the Go, I need a cable OTG with 2 ports: USB 2.0/3.0 (female, B sided) to a micro USB (male, A sided, grounded but with no resistance = 0K). Many of them exist on the market out there.
But it is quite impossible to use because of lack of power supply in the passive device (let’s say a handy 1T HDD usually powered via Host connexion !
Would it be possible to insert some sort of receptacle for AAA battery in the middle of such a cable to provide for power while you are for a long time out of access to an electric plug ? Does such a cable exist somewhere to buy ? What would be the sheme to mount this ? HELP !

Instead of shorting pin 4 and 5 from within the cable head, would it also be viable to short them from within the device itself? Say if I disassembled the phone to access the back of the female usb micro connector and soldered the pins. Would there be any damage caused if the permanently shorted pins 4 and 5 (within the device) is connected to a charging adapter/PC?

USB - Wiring for ADB?

Hi folks!
I want to connect an android device (it has usb slots... i can plug there 3g dongles, keyboards, wifi etc) with my computer to try to establish an adb session.
Is that possible like that (usb male - male)? Do i have to solder a custom cable - and how would he wiring be to force the android into "client mode"?
Any help is highly appreciated!

to wiring an usb cable is not so hard. normally you only need to solder the same coloured wire together, red to red, white to white, green to green and black to black. but there are already male to male cable to buy.
www.dx.com/p/ult-unite-ult-1234-usb...lated-data-connection-cable-white-60cm-269067
what does your android device have for an usb? is it micro usb or standard (type a)?
if you have a micro usb port so use an usb data cable, most of the charging cable does have data transfer support.
your computer even needs a driver for your android device to get working the adb.
good luck!
ps. on ytube there a lot vids how to... only search and destroy ( your android)

Hi! Thanks for your help! Its a type A jack on that device just like on the computer. Adbd daemon is on the device running but my windows machine cannot detect an usb device with direct soldered pins (or a bought cable which seems to have the same wiring)
I read about possible collitions when both devices of an usb connection are in host mode and that maybe pullup resistors on the data lines are needed - but i didnt fully understand that part. (Its different to the pin shortening of an usb otg wiring which can be found thousand times on google *G*)

can u describe exactly which cable u have used? and sometime the colors of the cable are not correct e.g. red is not +. those are build by chinese manufactures for cheaps goods. so u have even to measure the cable with a voltmeter.
and describe what happen when u plug the cable in the pc. normally windows is always running as main and android as slave.
as you describe u have an usb a type so i guess your android version is minimum 4.x and is already automatically on host status because you said u can put in a 3g dongle...so u have to go to the android command change from inside. i dont know much about linux programming so have to ask a developer. i only do developing hardwares not softwares, sorry for that.
what is your android device? with a datasheet is it better to solve your problem.

Hi KindsKoPP!
Thanks for your help and interest!
Basically I tested with a 1 to 1 wired cable I soldered by cutting 2 usb cables. I double checked colors (measured their output when connected to the computer) and found them ok. Then I connected them 1 to 1 (red-red, black-black, green-green, white-white).
But no usb device showing up or asking for drivers...
I know that adbd is running on the target device.
I pulled up some info here: http://www.valki.com/2014/12/04/analyse-av7/
I am still hoping that those usb devices who are in a double role (like our phones too with their usb otg host mode and client mode for mtp, adb...) are triggerable externally by using special soldered cables (resistors?) ... like "when resistor xy is on D+ -> go to client mode"?

12 pin usb connection

Hi,
I recently purchased a usb cable for my android head unit and the lead doesn't work. I didn't buy the unit so I don't know the brand etc. The unit was in the car when I bought the car.
I'm guessing the wires that plug into the usb connection are in the wrong order. I have no way of finding out the correct order. Does anyone on the forum know the correct order or even show me a picture of their usb cable.
I've bought 2 cables so far, neither of them have worked and they cost close the £100. It's very frustrating that I can't get them to work
Thanks in advance

What does the seller suggest and what happened when you tried that.
Also, with no information and detailed screenshots, how did you want help

When I plug in the usb cable and try any basic usb connections like phone chargers usb sticks etc. Nothing happens at all.
I've attached a screenshot from a product guide I found online if that helps.
If anyone knew which pins were for data transfer or voltage, that could help me loads.
Thanks

Measuring is the magic word. 8 pins will be connected in the original cable. (VBUS)+5V 2 times and 2x GND
...then you only have to find out what is D- and what is D+ for the data lines.
If you don´t want to measure: Open the magic box and have a look at the pins from the connector inside.
Just with your picture no one can tell anything. Each supplier does it´s own magic.
By the way... Connecting that wrong, may damage the internal USB-Hub and you can buy a new mainboard... just to mention. Trying around is not a good idea.
