after searching a little bit about 11 pin port in galaxy s3 and take apart an 11pin to 5 pin adapter i am thinking about make DIY smart dock for galaxy s3

i ordered mhl adapter and waiting for it mean while i tried to connect usb otg and extra micro usb connector together so i can use otg and charge the phone at the same time. but the problem is when i short ground and seance pin for otg ; charging doesn't work.
so any suggestion about the project?

i attached a plan of my project here

edited:after failing my 1st attempt i succeeded to make it work on my 2nd try!
this time i opened a 11 pin to 5 pin adapter. it has a small resistor which is connected ground to sense pin for hdmi out put. i removed that resistor and i connected 5 extra wire in the adapter 1. vcc 2. data+ 3. data - 4. sense 5. ground ( i showed in picture) . then i connected sense and ground with a 40.2k resistor.
then the 4 wire, which i i connected in 11 to 5 pin adapter (vcc, data+,data-, and ground) , goes to a femele usb where you will connect usb devices or usb hub.
and thats it!! hope you can try it too. if if have any other question just ask me

AW: diy smardock for galaxy s3
You forgot the vcc at the otg side, but anyway it can't work.
While charging you send 5v through the micro usb to the phone.
But in otg mode the phone will send 5v to the usb connector to supply power for the connected device.

I think your only chance is to use the inductive connectors to charge your phone while in otg mode.

There seems no way like you want it. I told you the problem.
You have to use the Pins for the wireless charger (QI-charger) under the battery cover.

charging via the back pins while in OTG mode with throw a message popup that says over current protection and shuts down the S3

at least it does on mine.

I have the smart dock and after opening, it does contain quite a bit of electronics

I have a suspicion that the IC to the left of the Realtek one is the brains of the board. The RT chip does the hdmi out conversion and the other two longer IC's are usb host and usb audio. Can't make out the printed data on the unknown chip, but my best bet is if we can get a dump of whats on there then we might have a good chance of DIY hdmi/otg capabilities. i'm no expert by far, but just throwing ideas out there.
