[Q] 11 Pin MHL + USB OTG - Galaxy S III Q&A, Help & Troubleshooting

Hey there, i have tried gathering information about this subject and it seems all threads always lead to this announcement:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
Short: Samsung have changed to an 11 Pin-out to enable USB OTG and MHL Hdmi out at the same time. I purchased an original HDTV Adapter (EPL-3FHUBEGSTD) which as far as i can reliably count indeed has about 11 connectors inside the USB connector that goes into the phone.
Now, i can get HDMI out just fine, but ONLY when i also connect the MHL adapter to a power source (a PC USB Port will do fine), however i have also read, that the phone is able to power the MHL adapter itself but obviously would not be charged then (no surprises there). This does not work however.
Further, connecting a USB OTG cable to the micro usb port on the MHL adapter does nothing. No notification and no devices connecting. No power either, since the LED on my USB Hub does not light up as it should. Connecting any devices to the hub does nothing to change that situation. If i leave out the MHL adapter and connect the USB OTG cable directly to the phone, everything works perfectly. I have tried this with 2 different OTG cables so they are not the problem.
This is an original genuine HDTV Adapter for our phones, which according to that post should be working fine with USB OTG.
AFAIK, this topic --does-- come up more frequently now as i can find a few more discussions about it, albeit none really helpful:

http://forum.xda-developers.com/showthread.php?t=1811435
That wiki entry is the most interesting link as it definitely states that using MHL and USB OTG simultaneously is possible and is also the reason why the 5 pin layout was changed to an 11 Pin layout.
Looking forward to reading your replies!

the ability to use MHL and OTG simultaneously would give the S3 so much more purpose. It is powerful enough to replace a desktop computer used only for light stuff like browsing and watching videos, and even simple gaming. If samsung made a dock like the one for the motorola atrix I'm convinced they will broaden their target group. The atrix got everything right with this but is inferior hardware wise. I love the idea of a one device for everything concept. Unfortunately it doesn't rhyme very well with the growth society.

Love the MHL and the OTG is even better only after I got the correct cables as the cables changed on S3 to the S2 version, unlimited space for watching films on my phone is now awesome and even better connecting it to to the TV just need a good dock,

is there perhaps any expert advise on this? According to multiple sources it should work but really doesnt. Did i buy the wrong mhl adapter?

I think they will only both work together when being used with an MHL enabled tv. That way the power comes from the tv and the usb on the adapter can be used for the usb-otg cable.

But if i connected the MHL with the s3. Would sound come out of my phone AND my TV or just my TV. If it justs comes out of my TV, then can i hook up my bluetooth headphones and listen to my video or it would not allow me?
Thanks

Ah ok sorry! Afaik you should be able to choose your headphones as primary audio source in the bluetooth settings. I know I can choose what I want to be output to my bluetooth headset, but I don't own an MHL adapter so I don't know about that. Someone with one should be able to try it, and if they don't own a bluetooth headset/pair of headphones they could try with wired ones and see what happens.

I have recently received an MHL connector (5 pin type) and the samsung 11 to 5 pin adapter for it. I can confirm that if I plug my OTG cable into it, and then into my powered USB hub, I can get the MHL to work just fine, both video and audio. The OTG cable powers it just fine, but does NOT allow me to use other devices attached to the USB hub.
I am still researching. I suspect you need to bring all 11 pins off the phone with a splitter of some sort, or possibly wire data lines through the MHL. Probably not with the 5 pin MHL connector and 11 to 5 pin adapter, but with the full 11 pin MHL adapter. I am not up to that level of hardware hacking. I suspect whoever does it first can sell a BUNCH of them!
Oh, and I have a Moto Lapdock for my Raspberry Pi, and would love to hook my S3 to it too!

MHL with HDMI and Power?

I've searched around the Forums for a bit and I cant seem to find an answer - so I thought I would just ask.
I found an MHL Adapter that does HDMI and Power, but I can only seem to f t for sale in EU : http://www.mobilefun.co.uk/bizlink-mhl-to-hdmi-adapter-black-p29839.htm
Has anyone seem a cable like this for sale either in the US or somewhere that will ship worldwide?
During lunch I watch movies/etc with my wife on an LCD in my dash, so I need the HDMI and Power to keep the phone going.
Thanks!
I thought all MHL adapters did HDMI and power. I thought that was the point of it over two separate ports. I might be wrong, though.

Yes, MHL standards dictate they do both.
MHL will ONLY charge if your TV is MHL compatible... Which it isn't. MHL ready TV's don't exist yet (AFAIK) MHL adapters are what he linked in the first post, which have a standard HDMI out with a Micro USB in, to charge the phone. That's what you need until you get a MHL TV.
I think the link the OP posted shows a dongle that plugs into the EVO 3D's port, and has two plugs, one HDMI, that would go to the tv, and a second plug to plug in a charger.
I really hope this phone supports full mirroring. I can't wait to get this adapter so I can test it out, hopefully before the 30 day period in case it doesn't work.
If anyone finds one for sale, let us know!
Thanks!

Yeah, I need a cable that will let me charge the phone and use the HDMI - So my total setup is actually going to be :
3D Evo -> HDMI cable to Composite converter for my Avid LCD in my car. So the avic doesnt provide HDMI power, thats why I need an adapter like my original post.

[Q] Dual micro USB?

Hi together,
ive asked me if it is possible to use an adapter for 1x micro usb (plug) -> 2x micro usb (jack).
Could the phone handle 2 USB devices at the same time?
Maybe then it is possible to use the HDMI output and the USB host parallel?
For example to use an TV as screen and an HDD as the source for a movie.
This would be nice.
Thanks in advance.
macc
When the connector is used for HDMI I doubt it can be used as USB at the same time, I'n sorry.
Maybe in a few months cyanogenmod provides a hack, if there will be an dual adapter soon.
We will see. Thank you.
macc
The hardware needs to allow this if it'd become possible. You need a really smart USB dongle that knows how to split the HDMI output from the USB output.
Sounds a little too difficult to ever happen.
Hmm thats right. I think i still dream xD
But thank you.
Sent from my GT-I9100 using Tapatalk
it is not possible. because as stated on this forum many times before, the type of usb connection is determined by the resistor between pin 4 and 5 of the micro usb connector. the strength can tell the phone, that there is either a charger, a pc connection, car kit, jig, usb otg or mhl connection present.
and i believe, this is an important thing to keep in mind for so many things:
for instance, why the original car kit triggers car mode and generic car charging cables don't or why not just any micro usb male to usb a female will work as a otg cable or why flashing should be done with the original usb cable...
so if you were to buy or build a micro usb hub, since it has no resistor in the very plug that connects to the phone, it cannot be used for anything but charging and quite frankly, i wouldn't connect more than one charger to the phone.
however, if you want to use your phone for presentations or watching movies and still be able to use it, get a bluetooth keyboard and mouse or a bluetooth presenter or do it the other way around and use a usb input device and transfer your media using allshare. everything else is physically impossible, so neither CM nor XDA can do anything about it. the only device that can do what you want is the new motorola. it has a separate micro usb and micro hdmi port and a docking station, so you can use it as a full notebook.
Thats obvious. Thank you.

[Q] HDMI Adapter in Box?

Did anyone receive the HDMI adapter in the box for the AT&T Galaxy S II ? I read that it should be included but did not receive it.
Nope. Not in the AT&T box
10 char xxxx
Nope. It doesn't come with AT&T version. AT&T version, all you get is the phone, battery, ac charger, usb cable, $25 media hub (tv shows only), manuals.
The infuse comes with one. The galaxy doesn't included one.

curoius, do most newer tv's have MHL built in? or probably not?
all i can find when i type my tv's model number and MHL into google is.. my tv with some hockey info (NHL) hehe..
google is too smart for its own good sometimes.
Based upon what I've seen, you need a MHL adapter for the phone. Its just a little box that plugs into USB, and had a USB port on it for power input and an HDMI port. There's cheap out there, like this one.
I have an MHL adapter and it does work but you need to plug the power into the thing in order for it to do anything. My receiver has usb and hdmi on the front so that works for me. It would be nice to have 1 cable, but this works.
Unfortunately I believe that's the case with any MHL device. There's a chip inside that box that transcribes the MHL signal (coming over the 5 pin USB connector) to a full HDMI signal, and it requires power. It's not all that bad though, as you would probably want to be charging your phone while playing a video anyways.
Exactly it is nice it does have power. Unlike the ipad to vga dongle lol.
Eventually most of the high end TVs will have the MHL. You will still need the adapter but you will not need to power it. The TV will not only power your phone but charge it.
I pocketed the HDMI MHL adapter from my infuse when I returned it under the 30 day ATT trial... The screen was pixelated in my infuse in the top left hand corner so they were more concerned with my device being defective than me just not liking it and only asked me if the charger was in the box.

NO.
Atrix has two different output ports. Micro USB for charging and data transfer, and micro-HDMI for TV-out. The laptop dock specific (I stress specific) for the Atrix uses BOTH of these ports in conjuction.
Galaxy S2 has ONE output port, a micro USB port that doubles for charging/data transfer, and connection to the optional MHL adapter accessory.
In NO WAY would you be able to MacGyver the Galaxy S2 to use the Atrix laptop dock.

You know... it just might work. The atrix lapdock does feed 5v power up the usb port which you could adapt from micro usb to whichever varient you need on your MHL cable. This would provide the power necessary to drive the hdmi circuitry that you had feeding into the micro hdmi input of the lapdock. Obviously you wouldnt have a true 'dock' but it sounds like you understand that. As long as your phone detected the mouse and keyboard as input devices it should work. Not sure how that operates with an MHL cable. It might require USB OTG, and im not sure if that is available over the USB connectivity provided by MHL. You could try with a standard usb keyboard If that works, then the lapdocks should too.
I know for certain that you can use the lapdock as the screen by just connecting the video out of the MHL adapter to the lapdock, and a usb power only cable (for the MHL adapter) to the lapdocks normal USB charge ports.

That thread is from the Atrix forum. What bearing does that have on the argument on getting this working on an S2??
Have you even looked at the connections involved here?
The Atrix's micro USB and micro HDMI port are side by side, and the dock plugs into both of them.
The MHL cable plugs into the ONLY port on the S2.
So I'm certainly not an expert on the inner workings of MHL, USB, and HDMI, but from what I can gather, you would have to splice an MHL cable to separate out the USB leads from the HDMI leads, then try to run the HDMI leads into a micro HDMI female port, and run the USB leads to a female micro USB port. I don't even know if that would work with MHL in the equation. I'm fairly certain the phone detects what is plugged in and decides how to use the port, which shoots this down idea down altogether... unless more hacking is involved into the OS. Which is way above my head, and I'm not fool enough to try.
See this thread, which is admittedly for the Galaxy Nexus, but is WAY more relevant than the Atrix thread you linked, as the GNex is also manufactured by Samsung, and also uses MHL technology.

No - the micro USB port on the side of the MHL adapter is for power. If the HDMI port you plug into is NOT MHL compliant (and not many are, yet), you need to plug an AC adapter in to power the phone while HDMI is in use.

Sure, there are a lot of MHL cables, but they are all essentially third party versions of the OEM Samsung MHL cable. (or whatever phone manufacturer you have that uses MHL - HTC, whatever)
I have high doubts ANY MHL cable will support it, since as I said, the phone will detect what type of connection is attached to decide how to send/receive signals from the port - if it sees the MHL adapter, it will do charge/HDMI; if it sees a regular USB cable, it will do charge/data transfer/OTG; if it sees an AC adapter, it does strictly charging. Notice how it can tell the difference when you have it plugged into your computer as opposed to when you have it plugged into the wall?
But if you want to go for it, good luck.
EDIT: yet another piece of info shooting this idea down.

i pretty much thought the usb and hdmi wouldnt work from the beginning, il have to look into modding the dock to allow bluetooth. ive have just looked at the specifications of a mhl even though they can in theory support usb and hdmi at the same time. the sg2 wont. and i cant see any software mod that would allow this. il see what sort of bluetooth mods are available. maybe incorporate stuff i have done in the past. but the dock is too good to pass by.
i think we can close this thread as its been answered.

Not to nitpick, but it's MHL 1.0 that won't support it. The GS2 just uses MHL. Who knows if there's a possibility to update it to whatever MHL 2.0 is, whenever it comes out.

actually the other thread is perfectly relevant, if you read it, you would understand the point of the thread is a howto on interfacing the lapdock with devices OTHER than the atrix, how could it be more relevant?

Sure, relevant. But not, at the same time. Look at post 10 of that thread. It says "The lapdock keyboard and touchpad work just like a normal USB keyboard and mouse."
Now, clearly I read the thread you linked. Did YOU read anything I linked, or watch the video featuring a spokesman from the frigging MHL consortium??? How he said HDMI out and USB will NOT work at the same time on any phone that utilizes MHL, not just the Galaxy S2? And goes on to explain why?

good luck m8 id love to see if you can pull this off!
you can always solder in a usb-Bluetooth tx so that the keypad and keyboard will work via bluetooth and hdmi via MHL. thats the only way

sounds like it's a possible solution, i'm trying to find a way to use the lapdock with my galaxy s3. any idea where we can get a usb-bluetooth tx? pair this setup with allshare dongle for wireless transmission to hdmi, we'll hv a total wireless solution to connect any phone to the lapdock?!

[Q] MHL cable and OTG cable

If you connect the MHL cable to the device and the OTG cable to the MHL cable the device can't detect the OTG cable.
How can I make this work? I've seen videos in youtube that they connect their device to the TV at the same they have USB bluetooth mouse and keyboard connected.
Anyone tried using MHL cable and OTG cable at the same time?

According to some of wikipedia entries it should be possible to use mhl and usb otg at the same time with a 11-pin mhl-hdmi adapter.
Wikipedia said:
11-pin MHL-USB Connector
The Samsung Galaxy S III uses a connector that is similar to the original 5-pin MHL-USB connector, but it uses 11-pins in order to achieve a few functional improvements over the 5-pin design.
It supports the use of USB and MHL simultaneously (note that the new Samsung 11-pin MHL-HDMI adapter also has a USB-OTG port).
Samsung’s Galaxy S III can power the MHL-HDMI adapter. Although this can theoretically also be done with the standard 5-pin micro-USB connector, the Galaxy S III's 11-pin connector is believed to be the first smartphone that supports this functionality.

Here you go.
So, it should work. But I couldnt make it work at the moment
I also got one of these 11-pin connectors and like it seems only the S3 has these adapters, so why the **** doesnt it work?? :/
I already asked sammy on facebook, just wondering what they will answer^^
Hopefully we will have some pos. results, dude.
cheers

How would that work since the micro USB connection on the mhl cable is for power / charger?
In those YouTube videos is it possible that they have the mhl cable connected to the TV and power source, and the keyboard and mouse connected wirelessly via Bluetooth?
Confused because you said USB Bluetooth mouse and keyboard. From what I know they aren't USB.

Samsung should eventually release a dock to use both so unless someone figures it out first you'll just have to wait, because if it just took an 11 pin USB cable someone would have got it working already and we'd know about it, so I reckon it might have some extra circuitry to make it recognised by the phone.
Guys, as I already posted, the connector has 11 pins, so it should be possible to use OTG and MHL features at the same time. thats the only reason sammy brought out this connector and also cause of incompability with the 5-pin connector.
So they should bring the f*ck out somethin for the phone that activates this feature.
And a big problem I have with my mhl-connector is that I cant configure the output
on my 2 TVs at home I get 1080i, (both only 1080i capable), but the picture is kinda oversized so I cant see 100% percent of the picture, only 90% or smt like this.
But the funny part is, that I get on my 1680x1050p PC monitor only 576p screen, what actually sucks So it would be awesome if I could choose the resolution I want to have. But I guess its a thing of the connector (maybe it choose the resolutions iself).
cheers
so the one in the videos using keyboard and mouse are bluetooth thru phone?

I am SO HARD waiting for THAT "DOCK" hopefully will came out any day soon.
They should do iut fast. I'm waiting so hard for everything get connected with my Phone. It will be awsome if I don't need my Pc anymore.
To use the MHL cable you must have power connected to the adapter.

That's damn funny because I have wanted to know whether that would work as well, lol.
Did seriously consider trying but as I was on holiday if they broke, I wouldn't be able to get replacement so didn't try it.
In theory I would think it could work, but only if you could somehow wire in power to the hdmi adapter as it appears to need that to run the hdmi aswell as provide power to the phone, at least enough that once the usb adapter tries to demand power to run it isn't enough for the phone to output.
As to whether this is just a a stupid guess and assumption of how the devices and being a noob, I don't know.
If you can get a micro female to male adapter with a usb splitter for power then technically I can't see why it wouldn't work if the limitations are physical as oppose to software based (whole other issue I have no clue about).
EDIT: Wow, when I started that post no one had replied, err, seems a little redundant now, lol. My bad. Also, this 5 minute wait to point this out, have seemed really long...
guess we'll have to wait for that dock.
