Hello, I've an interesting hardware question for you, xda community
My HTC HD2 falled down from the table while it was in charghing (so with usb cable connected).
The usb port broke, so I improvised a teardown to check the micro USB port pins on the motherboard.
I reach to reconnect power pins, so the phone charges correctly, but i'm not been able to find alternative points for data pins becouse of broken electric paths on the MB.
Now I'm searching for alternative points to restore totally the usb functionality.
Anyone (with a broken HD2 MB) can check where electric paths go UNDER the usb connector on the MB? ..or suggest me where I can find alternative points like factory usb testpoints on the MB?
many thanks in advance and sorry for my bad english...

Hi all,
I have a CHT 9000, and the mini usb charge cable just wont charge it.
After inspection, I determined the source of the problem - damaged mini usb port pins, bent and loose, that cable wont even touch the pins to charge...
I need to know how to replace that mini usb charge port connector...
Thanks

Thankfully that is a part which is relatively easy to solder. Armed with a fine point soldering iron it's not too difficult at all. If I remember it has either 2 or 4 soldered anchor points and then of course the fine connections at the back end.
You may find a new port online or buy up a device that is being parted out.
For full functionality you need the 11 pin type (Not the 4 or 5 pin). See here:

I have Hima with broken connector. Now i want replace them with usb mini connector.
Pinout is on http://forum.xda-developers.com/wiki/index.php?title=Connectors
I want to join pins 13*14*15 and 16-17-18GND with USB 1-3-2-4pins
But I still have one question... May I also connect three pins 20,21,22 to pin 13(+5v) if I want to recharge batteries directly from usb?
No need to connect all that pins: http://forum.xda-developers.com/showpost.php?p=10453499&postcount=71 and: http://forum.xda-developers.com/showpost.php?p=10467485&postcount=73
Thank you very much. I was looking for it here,but my English is´nt good.
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.

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"?
USB connection problem
No change in device manager happened even in fastboot mod, it's only changing, I test a lot of way for solving but no ways help me, if there is a solution, tell me. Thanks
Sounds like the USB port needs to be replaced on the phone.

can u explain more
I'm sorry Guy's, but I have to go for a monthly, but thread is open for your comment and solution!
There is an internal ribbon cable that connects the USB port to the motherboard.
I believe this internal cable needs to be replaced if trying different computers, USB cables, and USB 2.0 ports doesn't solve the problem.
I fix my phone problem, a repairman change my micro USB socket.
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.
