I have googled for quite a while, and have not found the pinout on the microUSB port. I really want to know if there is any way to get analog output from that port like my old G1. It would be nice to have one port for charging and audio (for cars, docks, and boomboxes).

Thanks for that. But I wonder how that port will provide audio with something like this?

ok, I am just curious, but you dont want to use the audio output on the top of the phone just to have an all in one solution, correct? Because I have no clue what would happen hooking that adapter up, curious though.
It has to be built into the port as well as the software to control it. I've got my money on it not working, since it's not supported by the phone. HTC ditched the USB headphones a while back because everyone complained about having to use special headphones and adapters, hence why they all have standard headphone jacks now.

Exactly. Having a dock or boombox that would be plug and play would be nice. I'm actually considering something for the car that would replace a head unit. Maybe there would be a way to snag the digital audio from the HDMI port? Digging continues.
Worse case scenario, I use the USB port for power and bluetooth the audio.
I dont think it is possible through hdmi without a digital to analog converter, which are rather expensive. The hdmi out is pure digital goodness.

Lol, I guess for me 50 bucks is rather expensive to free up a wire. But to each his own

Have you seen what Apple charges for white cables? LOL! I think $50 works.
Lol, fair enough
HTC ExtUSB Micro?
I am looking for the same info.
Is the micro usb port on the evo just a standard 5 pin only?
The mini usb on the hero was the non-standard HTC ExtUSB with 11 pins. I loved this because I could make my own docks that included power and audio with only one plug.
Maybe the HTC micro b is analogous? HTC ExtUSB Micro?
I dont think so, it's only 5 pins. And I think the only reason HTC had the 11 pin was to provide the proper support for audio out. Since the evo has a 3.5 mm I dont think it is even possible to do that.

And how exactly do you intend to convert the HDMI to a digital RCA or TOSLINKi nterface as that box requires? Oh, another $50+ box? Yeah, that's what I thought. So, $100 or a cable that looks "silly". I know where my money would go...
The Samsung Fascinate has this audio/usb option. Their docking station has a micro-usb plug and then a USB (power) jack and a standard audio jack out. So it doesn't require any special decoder, there must be audio out pins just like in the iPhone/iTouch?
Take a peek at this photo of an Evo's circuit board. Specifically, the solder points for the microUSB port (including the ground/anchor points):
http://guide-images.ifixit.net/igi/22dlA5ZuptWCyvTX.huge (from http://www.ifixit.com/Teardown/HTC-Evo-4G-Teardown/2979/1 )
Count 'em. Eleven, just like extUSB on the Hero & other HTC phones. Looks like the Evo has what could legitimately be called a "HTC micro-extUSB" port, and not merely a standard "micro-USB" port.
Now... good luck trying to find a CABLE with all 11 contacts and wires on it. If it exists, Digikey probably has them... but god only knows where that needle might be in their million-part haystack (anyone who's ever tried finding a specific connector, even a common one, at digikey.com if you don't know its exact OEM part number knows the joy I'm describing...)
Chances are, there's a (~2.7v) serial UART sitting on two of those pins, too.
(update: found a few references to "Micro extUSB" with regard to the Desire, including http://windowsmobilesmartphone.forumcommunity.net/?t=39522724 )

Nope. It's definitely the Micro USB connector. I know this is an old thread, but I've been trying to do some research on this port in hopes of hacking my own car dock.
I've found some additional information on this Micro ExtUSB™ port. The HTC Incredible uses it for its TV Out port. See this Thread on AndroidForums. There's even a special cable for the Incredible at HTCPedia. I'm very tempted to buy the cable to use it as a sort of breakout box to experiment with this port.

I believe your looking at the micro hdmi port, the usb is indeed 5 pins.
I'm pretty certain it's just a standard 5-pin MicroUSB port. Just shining a flashlight into the port, I only see 5 pins.
It would be really nice if there was a standard connector that supported power, USB, audio, and some sort of control bus. The Apple dock connector is a bit big, but it allows for a lot more than microUSB can do. Though I guess it could be done over USB if there was a standard for it.
Hey There,
I've seen the pinout for the original Galaxy Tab, does anyone know if this one is the same?
Or if not, anyone know where I could find a pinout for the thing? I might try calling Samsung but I have no idea how much time that will take or if its worth it.
Also, anybody know where to source the raw connectors?
Thanks!
Pinout should be the same since cables and accessories for the 7" work with the 10.1 as well
Here is the thread that has the Tab pinout
Cool, thanks. Now I just need to source that connector...
I would assume some pins are the same but expect many have changed. Since our device has HDMI and USB hosting, there are probably some differences. I would love to be able to make or buy a breakout cable that had everything possible out of it. Right now all the official accessories look to do only one thing at a time.
And I have beef with any accessory that calls themselves a media dock and then doesn't have multimedia outputs. Had to get that out there
Well,
I finally found a source for some connectors:
http://www.kineteka.com/galaxy-tab-connector.aspx
and they have a breakout board:
http://shop.kineteka.com/products/200-samsung-tabbreakout.aspx
I've ordered one of each and will report back.
They clearly say "Galaxy Tab" and not Galaxy Tab 10.1, but if its the same connector, it should be fine.
Though I agree that our unit most likely has more outputs. It would be really nice to figure out what those are! I have a thread at the Samsung Innovator website about it:
http://innovator.samsungmobile.com/...ate=&endDate=&searchTypeForm=&searchTextForm=
But I feel like they won't tell us. I may have to buy the USB host adapter and the HDMI adapters and crack them open.
Anyway, I'll try to figure this out. If anyone else knows, please fill me in!
-Taylor
In the kernel, drivers/accessory/30pin_con.c:
if (acc_adc != false) {
if ((2600 < acc_adc) && (2800 > acc_adc)) {
env_ptr = "ACCESSORY=OTG";
acc->current_accessory = ACCESSORY_OTG;
The acc_adc is the arbitrarily scaled resistor value on the ID pin. I think there might be a place in sysfs to read this out, so you could wire up a potentiometer and work out the real resistor value for this range (2600-2800). You can use ADBWireless to get a shell while you are messing with the connector.
Once in OTG mode, the USB D+/D- pins used by the sync cable should become USB host.
Ah, I was afraid of that, I know plenty of mobile devices work that way. I was really hoping it had two separate ports like some other tablets, so I can use my accessory and the USB host port at the same time. I may have to do some juggling then, grr.
Thanks for getting that info though! I'll try that with my breakout board when it comes in (if they ever ship the damn thing...).
In another post, a guy put 20K ohms between Pin 13 and Pin 15 and got the Tab to go into host mode. Then the following for the other pins
Pin 1 (GND)> Black
Pin 3 (D+) > Green
Pin 4 (D-) > White
Pin 6 (+5v)> Red
If anyone figures out how to get HDMI out, please share.
Does no1 else see the need in someone producing a 1male -2female splitter for our phone considering we do not have a seperate hdmi connection. It would be great to use the otg cable along with hdmi. So we can use keyboard and mouse hookup to the tv etc.... Ive looked all over the internet for one and have not come across one yet. So if anyone is capable of making one i will be your first customer. lol
if you notice, on those MHL to HDMI connectors, they all provide a spare microUSB port in the adapter, so that you can continue to hook up more stuff to your phone, and charger your phone
the spare port is for a micro USB power input. the video out display will not work if it isnt plugged in, at least mine won't. Bluetooth controller maybe?
thanks for the replies
I guess i will have either pay someone to make one or wait to see if there will be a demand for it. Thanks again for the replies
so, anyone taken apart an MHL adapter yet?
i have a sneaking suspicion, that the move to an 11 pin is what will allow BOTH OTG, and MHL at the same time, but i could be wrong.
look inside your USB port on the bottom of the S3...
whatya see?
the normal 5 pins on the USB part.. but what is that in back wall? THE OTHER 6 PINS!
yep, that is why you cannot plug the MHL adapter into a hub or anything.. there is 6 pins are missing.
Now, i am wondering:
has anyone taken it apart to see if the 6 pins are used alone, or if it uses the the USB also?
if it uses only the 6 pins for MHL-ness, then it should more than possible to make an OTG/MHL adapter/dock.
more thought says, if my theory is right, an 11 pin to 5 pin conveter may be the key.. and an otg can be spliced in to give 2 outputs: MHL in one (using an s2 MHL adapter) and OTG in the other.....
anyone wanna tear their adapter up? or are you guys gonna make me spend some money?
I ran across this post looking to see if anyone has done this yet. I am going to try to grab the 5 to 11 tomorrow and tear it apart (since it's the cheaper adapter). My plan was to rip it apart and if the original 5 pins are available, splice just as you mentioned.
I can't find a decent picture of the microUSB plug to see if all pins are there.
Also I found this:
http://homixtech.en.alibaba.com/pro...Galaxy_S3_11pin_To_Micro_USB_5pin_Gender.html
Which makes me think 11 pin microUSB plugs that work are available out there somewhere.

So, did you do this experiment? Has anybody found a way to get access to all of the pins and make OTG work with MHL?
I've been waiting for two months for an answer about this. I'm glad someone started a thread. I kind of have this hesitation to start new threads.
I would love it if this could be integrated with the seidio active dock.

meh, I think that is wrong. many people have done exactly what it says you can do, and it doesn't work.
Makes me wonder if the boys at Samsung made a press mistake. If indeed you can't use both with the correct cable, then why make a port with 11 pins? Seems a waste of resources to me.

I have never seen anything from samsung saying that MHL and OTG was possible.. just speculation in websites.
It better be possible because if not all Samsung's managed to do is make us buy hugely overpriced new MHL cables when they could have kept the old type, but I guess Samsung's made some decent money giving people no option but to buy £30 MHL cables.
I hope Monoprice really is working on a cable. 35-40 USD is more than I want to pay, especially if I get a couple and/or an HDMI dock.

Both the oem adapters are missing 2 data pins within the plug needed for simultaneous usb connectivity with mhl,I've ordered a Chinese alternative that I'm hoping will have all 11 pins,I'll report back If I have any success

Someone needs to find the resistor values first so the phone can use both simultaneously if it's even possible that is.

that would be key. I have sent out messages to people that may know, or may be able to find out, but i have not had success.
heck, If it can be done in the terminal (turning on items) i can make a shortcut that would do it.. but i have had no success with that either.
It's not possible I think.
You can use an MHL enabled tv wich powers MHL, (so you don't need the adapter) but how do you want to split that?
You can split the cables from the samsung adapter, so you have the MHL ones(6) and the usb ones(5).
But what then?
You need to connect the MHL ones to an hdmi cable, and connect it with an MHL enabled tv. And the usb ones to an usb port for OTG.
But will that even work with this S3?, because it is designed to get power from your charger via the extra usb port on the adapter.
Maybe it only works with the adapter, and not even with an MHl enabled tv...
I think somebody needs to connect the S3 to an MHL enabled tv, if that works you can modify the adapter and use the usb as OTG.

I found (and shared) the MHL value, and we already know the OTG value.. but it only seems logical there is ANOTHER value to activate both at the same time. we are postulating, the the reasoning behind the 11 pin, is to allow both. If adding just an OTG cable turned on MHL too, it would cause issues without an MHL connection. and the same with MHL activating OTG, without an OTG device connected. like i said, this is postulation at the moment, but there SHOULD be a thrid value to enable both at the same time. that value would be used by a future peice of hardware that does a whole "PC MODE".
and if it does not exist, it CAN be done, we just need more "stuff" a way to enable a special switch if you will.
some people are saying you can connect straight to an MHL enabled TV, but that has not been done yet (and since there are no 11 pin MHL cables, that are not adapters, it seem unlikell that anyone will until said cable exists. the S3 cannot send MHL signal over the usb part, it has to be either the extra 6 pins, or with the 11 to 5 pin adapter.)
essentially, the pins are there, and with some special software, or a hidden resistor value as to yet, unfound, and some custom hardware (as of now NOTHING 11 pin, has 11 pins in it) it SHOULD be possible.
but there is nothing that has been found (hardware wise) that is even modifyable to work.... yet.
What I don't understand, why does MHL only work with the power connected?
They could easily make an MHL cable with the 11 pin, and hdmi. That should work for only MHL.
Only no go I can think is that MHL drains your battery because of always having your screen on, and the MHL output.
So they decided to use the adapter with power, otherwise you can't use MHL feature very long before your battery is empty
I think inside the adapter they only use the pins for giving power, and not the full 5 pin support for OTG, and therefore OTG doesn't work when you want to connect something.
Inside the ROM they have maybe build in something that MHL will only work when power is connected.
Maybe the solution is very simple,modify the adapter so full 5 pins are connected.
Hi All,
Long time listener but first time poster. I recently installed a Eonon ga6163f into a Mazda 3 and have a customer ROM image running after a load of reading and trial and error. All seems reasonably good considering the hardware isn't new nor that capable by todays standards. I am going for it and looking to include a DAB+ USB adapter. I do not have any HA to USB cables and aren't able to find a source for these. I will need to roll my own.
Would anyone be kind enough to share the USB pinout - maybe a close up photo of the cable on the HA side that plugs into the 'H' port of the ga6163f?
Any details of where each pin goes, such as if it is for USB1 or USB2.
I have only been able to find snippets of details but not enough to clearly figure out which port is USB1 or USB2 and the corresponding VCC, GND or data pins for each USB port. There also looks to be an RCAish looking lead in that cable bundle also. No idea what that one is for either but I don't think I'll be needing it.
Any help greatly appreciated.
Many thanks,
