thx for the link , yah i saw this one and the pic show round tip so i am confused. i will PM the seller, btw id rather have the cable itself without charger. cheers
If you just need one of the USB plugs to power something, you can splice another (power only) miniUSB into a normal lead. Just connect the Red to Red and the Black to Black, tape it up (or use heat shrink).
To double head a cable would require a hub to be built in, which would require a chip to do the data separation and sequencing.

[Q] Broken connecor - charging through USBCable

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.

[Q] USB alt points on HD2 motherboard to recovery USB functions

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...

Put SSD inside SATV and connect through USB

Hello,
I'm thinking on buying an SSD or mSATA SSD to use as adoptive storage, putting it inside my SATV 16GB and somehow pass an USB cable from the inside to the outside to connect it through USB, this way the SSD would stay inside the SATV and I don't have to worry about carrying it around.
Anyone have any ideas on how to pass the USB cable from the inside to the outside of the Shield without drilling any holes in the chassis? The idea would be to site the SSD on the place the PRO have the HDD and connect it through USB.
Did someone attempt this? Smile
Thanks!
You could do that, but I think the only viable solution would be to strip down the connecting usb cable, and solder wire directly in the usb plugs on the SATV.
You could probably do it from the inside. You can finde some teardown pictures of the SATV here:

I don't know the points to solder the cable and I'm afraid I can damage the port.

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.
