Yeah, CM has issues with (at least) MHL con S2/S3, dunno if it has them with S4 as well.

I don't even know if OTG works with CM

Can't you use the mhl adapter and then connect a Bluetooth air fly mouse/keyboard to the phone itself for navigation / typing? I am asking because I am interested in this. I can't seem to find info on a good Bluetooth keyboard mouse combo.
[Galaxy S III Accessories] romulusram:
Yes, I'm saying to use a USB Keyboard/Mouse + HUB + MHL all at the same time.

And No, im not saying to to connect the MHL to the HUB first, of course that wouldn't work.

Right, there is no Female USB port but from my understanding the official adapter (EPL-3FHUBEGSTD) has a MicroUSB Female input that needs to plug into power correct?

Well why not connect the MicroUSB-OTG cable to this port, and then connect a Powered USB hub with a Keyboard and Mouse on the other end.
[Galaxy S III Accessories] harryville:
That should work. Anyone tried it yet? Need a micro usb otg cable.
[Galaxy S III Accessories] jellydroid13:
Can the S3 charge through an OTG cable?
[Galaxy S III Accessories] DarkManX4lf:
So basically what you want to do is like the Motorola desktop dock where you can plug the phone into a monitor or tv and use a keyboard and mouse.

This would be great.
[Galaxy S III Accessories] mertzi:
some people ask "why not use bluetooth keyboard/mouse" and i'm with the OT on this, I already have a good wireless logitech keyboard and mouse for my win 7 desktop that connects to one receiver with logitechs unifying technology and I have one spare, so it would be much easier to be able to use them both for my computer and for my S3. I've heard that the unifying receiver works via OTG, so you'd only need one usb port, so a dock or adapter of any kind that gives the ability to use MHL and OTG simultaneously would kick ass!

And the possibility to output a higher res than 1280x720 other than when showing 1080 videos would also be nice

Magic Connector

Hi, I guess we won't be able to get the right solution until something like a "splitter" gets in the market (or "gets" done) AND it would still be a mistery if S3 would support that config:

S3 - { Splitter -11 pins }-PWR'dMHL-HDMIScreen

{ |-5 pins }-OTG-PWR'dHUB(to support devices)-Mouse&KB&Disk&etc

{ |_PWR?}-PWR(To charge S3)

Note the "Connection kit" is just OTG+PWDHUB+CardReader implementation (Ie, No possibility to connect MHL)

HDMI Dock = Bulkier Samsung HDMI. No possibility to connect OTG.

Aweee thats too bad... I guess your the first one that tried this.. So why did Samsung change the Pin connection then? I thought it was to enable USB OTG?

I have tried hooking up a USB OTG cable to the official EPL-3FHUBEGSTD adaptor on Jelly Bean and ICS Stock roms but could never get it to work. Separately the cables work perfectly fine, but simultaneously i cannot get them to work at all.

If anyone has a solution or an idea please let me know. I have already contacted Ghokanmoral on this since he is a kernel dev and coul look into the driver for us (im hoping).
[Galaxy S III Accessories] TheBlackCat13:
Is it the official samsung OTG cable? Normally the USB port on the MHL adapter is for power, but normal OTG cables draw power. Maybe the official adapter would be different. I am not sure about that, it is just the only thing I can think of. However, it will likely suck power like there is no tomorrow.
[Galaxy S III Accessories] dennisfisch:
a USB OTG cable is really only a USB cable with a 5th connector shorted to ground, and there is absolutely no reason whatsoever for samsung to introduce another proprietary cable...

However, i cannot test for this since I do not have an official samsung USB OTG cable
[Galaxy S III Accessories] Tularis:
The only thing that remains a possibility under my point of view is to get the 5 to 11 pins official adapter and check the pin layout to know which are the MHL pins, then "open" the adapter and try to split the microUSB into two different ports, the one for MHL and one extra for OTG, after that test it and then get angry because of wasting 10 bucks for breaking the adapter...
[Galaxy S III Accessories] scarrmrcc:
I have ordered one last week, for just such an experiment, and it should be here this week. I figure 10 bucks is worth the gamble... because it is highly unlikely that it will go back together with any sort of prettiness....I make things work, I do not make things pretty.

EIA2UHUNBE, EPL-3FHU, or EPL-FU10BEBSTD?

From my research...

The EIA2UHUNBE cable is a 5 pin Samsung OEM cable, or adapter, (adapts the phone's 5 pin micro USB output to a TV's HDMI input) that allows all Samsung MHL phones (Except the Galaxy S III) to mirror their screen on an HD TV. It costs $30 to $35.

The Galaxy S III has an upgraded 11 pin micro USB connection that DOES allow for use of USB OTG accessories while simultaneously outputting a mirrored screen on an HD TV. The ONE AND ONLY cable, or adapter, that will accomplish this is the 11 pin EPL-3FHU cable adapter (adapts the phone's 11 pin micro USB output to a TV's HDMI input AND a USB OTG connection). It costs around $40.

The EPL-FU10BEBSTD is an 11 pin to 5 pin adapter (but not a cable) that downgrades your Galaxy S III connection so that it will work with the older EIA2UHUNBE cable adapter. It costs $10 to $15. When used, the phone now no longer uses all 11 pins in it's connector, only 5 are used. Therefore, only mirroring will work, or USB OTG will work, but not both at the same time.

Can someone verify?
[Galaxy S III Accessories] alexx910:
Got the 11-Pin MHL- Cable mentioned in the post above. And I think, I got the answer, finally.

One question to you guys, do you have a tv with MHL-Support???? No? me neither, so if you dont have a new samsung, sony, lg or whatever tv with mhl-support, you cannot use this feature, cause the phone doesnt get charged over mhl and need the additional micro-usb-port for charging instead of using other stuff.

I'm gonna tell more, asap I got my new mhl-enabled 46 inch tv :D
[Galaxy S III Accessories] Tularis:
I agree with you in all but that the MHL EPL-3FHU cable adapter does allow USB-OTG, I have not seen it yet working simultaneously...

Alexx910 I hope using an MHL TV will not be the matter...I'm not going to change my TV... waiting for your information :)
[Galaxy S III Accessories] scarrmrcc:
it has been tested and tried repeatedly, and the EPL-3FHU does not allow for OTG.
[Galaxy S III Accessories] dennisfisch:
I have the exact EPL-3FHU(BEGSTD) cable you mention, alas with no USB OTG working. I intentionelly went with official Samsung parts on this to rule out any 3rd party incompatibilities. It's the exact cable said to work with the Galaxy S III.

Hey there, from my research it has been suggested that the 11 Pin connector is in fact 2 USB ports in one, where one would be used for MHL and the other for USB OTG, though there is no authoritative source for this information. Anyhow, if this is true, then your statement would no matter, as 2 separate channels are used.

As for your cable, did you modify it in any way to workaround the issue you mentioned or is it a standard OTG cable? Those can be had for a mere $1 or $2 anywhere...

I'm happy we're having this active live disucssion, it seems this might finally get the attention it deserves. Just imagine how much more our phones will be capable of. People suggested earlier to just ignore this issue and go for bluetooth keyboards and mice to get a "desktop like experience", but this wouldnt allow the use of external storage or other devices (cameras, gamepads, joysticks, you name it).

I'm using my phone to play N64 games with >2 people simultaneously on a HDTV (using WiiMotes) but would love to be able to additionally connect other gamepads or even browse the internet, youtube, whatever and using the phone like a laptop kind of.

Not wishing for pony's here, since this feature is supported and should work...

Hi,

I thought one thing,

Search on amazon

USB A Female a USB A Female

I can't put the link.

This adapter can transform the standard cable to OTG.

It 'correct what I say? Anyone has ever tried it?
[Galaxy S III Accessories] scarrmrcc:
no. that is not how it works. you need to have pin 4 connected to pin 5 on the miniusb side of the cable.

and since otg cables are UNDER $1 shipped from amazon, and ebay.. i do not see why everyone is desparate to find an alternate way to get one. just spend the couple of cents and buy an OTG cable.
[Galaxy S III Accessories] NuclearEMP:
this feature is not possible until the TV itself supports MHL.

as of now you can only use one at a time.
[Galaxy S III Accessories] bradleyw801:
I did a ton of searching, and couldn't find if anyone who had successfully tried a wireless USB hub, but theoretically that should work right? I am thinking something like this = http://www.shopiogear.com/store/iogear/en_US/pd/productID.234235600

I didn't go price shopping, I just took the first item that was what I was looking for. What I don't know is what software would be required on the android end to connect to something like this. But, if Android could find it, then you could have all your USB devices connected, and still use the microUSB port for the MHL cable.
[Galaxy S III Accessories] woody1:
Has anybody actually tested to confirm that connecting the S3 adapter to a TV that supports MHL will also allow you to use the micro-usb port on the adapter to connect to OTG devices? If so, I haven't heard of it.

If it's true that using the adapter with an MHL-enabled TV will allow OTG support, then I would guess that somebody could rig up an adapter that would go between the Samsung MHL/HDMI adapter and a regular TV to supply the power that would normally be supplied by the MHL interface by the TV. If there's a way to make this work, I believe somebody will engineer a way to do it.
[Galaxy S III Accessories] strange1712:
Has anybody got an S3 Schematic yet? So we know for once and all if we've got MHL-USB on 6(why 6?) additional pins at the back or just some kind of standards-trolling-SAMSUNG?

It cannot be 2 equal USB ports, as then standard MHL's would work, so even in that case S3 has a way to differentiate each one (That would explain an additional pin).
[Galaxy S III Accessories] TheBlackCat13:
Is that really necessary? I am no expert, but I would think looking at the standard Samsung 11-5 pin MHL adapter would be enough. Stick an ohmmeter on each pin on one side and see which pin on the other side it is connected to.

If the pins on the male side that would be needed to run USB OTG are not be connected to anything on the female side then we are in good shape, it should be possible to run the two in parallel. On the other hand there may be some specific pins that are connected to both (like the ID pin), which means there is probably something in the USB controller that detects whether USB, MHL, OTG, or some combination is being used, which means it might be harder without having an official Samsung version to reverse-engineer.
[Galaxy S III Accessories] scarrmrcc:
I just got my 11pin to 5 pin converter... and have gotten it open.. bad news. there is a resistor from pin 4 to pin 5 in the USB plug part. That means that it may be hard to nearly impossible to get this to work.

anyway, there is some interesting info:

on the usb it uses:

pin1=+5 volts

pin5=ground

pin4=resistor to ground (need to test to see what it is)

on the 6 upper pins, it uses (starting from the right, if looking down at it) pins 2, 3 and 4. It looks like pins 1,5, and 6 are not doing anything.

oddly, on the usb socket side, there seems to be 7 pins going into the connector.. i must research more.
[Galaxy S III Accessories] Tularis:
Could you post some pictures or a diagram?

Thank you!!

[Galaxy S III Accessories] scarrmrcc:
how's that?

I am going to talk to some ROM devopers and see if it might be possible to make a special ROM mod, that would see this resistor, and turn on both.. because as you can see, the data lines (2 and 3 on the usb) are not connected to anything.

if they can make the software play nice, i can make the hardware work too.

EDIT:

I just realized.. this is a kernel thing.

(i am basing this on the fact that -Imoseyons Lean Kernel DOES NOT actually have fast charge autoswitching, and need a command line entered.)
[Galaxy S III Accessories] Tularis:
Thank you for the pictures. Ok, I'll give my opinion:

1- I'm a bit confused, the female microUSB I see here has 7 pins... should have 5+cover

2- On the side of the phone, pin 4 is used to check what is connected varying the resistor value :

-Open means nothing, used to sync data or charge

-Short means USB OTG

-365k means dock

-619k means car mode

-R? means MHL adapter

In all cases this resistor is connected to pin 5, GND.

3- So, the pinout would be on the 11 pin male microUSB:

-USB 5 pins

1)5V connected

2)Data - not connected

3)Data+ not connected

4)ID. R connected to 5)GND

5)GND. connected to GND

-Extra 6 pins: I cannot say where do they go until I know the pinout of the 5pin side, I can only say that point b/a is 1, 5V (can you provide it checking continuity? I still see 7 pins...)

6) not connected

7) connected to ?

8) connected to ?

9) connected to ?

10) not connected

11) not connected

We must remember this is the adapter, not the official MHL cable. Until now, the diagram would remain like this:

Would be nice to know the valur of the resistor as well.
[Galaxy S III Accessories] scarrmrcc:
close, but i can explain point 1:

1. The female usb has 7: the normal 5 + cover (i guess), and (drumroll) there is a blade pin right on the lower end of the plastic part that sticks out. the galaxy s2 has that, and a quick google search shows that they are in fact 7 pin (still looking for the pinout.)

2. yep, as soon as i find a multimeter, i will find that value

bonus: i have found that one of the USB cords i too apart recently has compatible pins to get all 5 in the USB side...

i would prefer to find a place selling 11 pin plugs though... especially on a board for mocking up a super dock.
[Galaxy S III Accessories] Tularis:
Sorry, I can not find the pinout for female microUSB 7-pins.

I think that would be almost impossible to find the 11 pins micro USB male, I wish I'm wrong... indeed,I'm also very interested

Has someone inside pictures of a typical 5 pins MHL adapter cable (the one that is not suitable for S3), it would be very interesting to check if it also has the resistor and if it is the same value.
[Galaxy S III Accessories] scarrmrcc:
The 11 pin plugs exist.. someone posted a link once... (I do not remember where)

and there are a couple of aftermarket 11 to 5 pin adapter, and even full out 11 pin MHL adapter now. it is a matter of time... a matter of time.
[Galaxy S III Accessories] Tularis:
Its true that Samsung's phones use the microUSB 7 pin but the only information I've found is that it have 2 GND (guess the typical one and the cover maybe) and 2 powers, one for battery and one for charging but I do not know the pinout or if this is even true... need a multimeter hahaha

I found that the FSA9280A chip is the one behind checking what is connected in the USB for galaxy S/S2, here since we have more pins I guess it would be another one or it would have some mod. Maybe taking a look in this video we can see which one it is:

[Galaxy S III Accessories] jmarkoa:
dennisfisch,

Did you actually mean to say you DO have USB OTG working, but just not in conjunction with the HDMI output? I thought the only issue here was BOTH working together?

Also, does your "original" cable adapter have the EPL-3FHUBEGSTD model info stamped on it? The reason I ask, I purchased an "original" on Amazon but instead was sent the 5 pin cable with the additional small adapter. WHY did I try to save a few bucks... I hope to have the 11 pin EPL-3FHUBE sent from Samsung next week. I still wonder if others are just confusing these adapter cables...

Anyway, if you know you have the real deal 11 pin cable adapter, have you tried it with an MHL compliant HDTV? A trip to Best Buy could be a quick answer... First thing to find out is if the proper MHL TV will provide power without the use of an independent power supply.
[Galaxy S III Accessories] :
If I were you, I'd send it back to Amazon for the product not being as described. Even if it wasn't shipped/sold directly from Amazon LLC, they still pay shipping charges and refund the whole thing for you.
[Galaxy S III Accessories] scarrmrcc:
it HAS been tried, and was not successful. it is due to a lack of thae data pins being connected, and the fact that the trigger to turn OTG is shorting out the 4th pin, and the trigger to turn on MHL is 1.005k resistor on the 4th pin. we need some custom Kernel work for this to happen.
[Galaxy S III Accessories] jmarkoa:
Will do, Monday.

For those of you that have achieved USB OTG success, what was the setup? Just that special OTG adapter straight out of the phone to a regular full size USB device? Or, has anyone been successful going through the 11 pin adapter cable, then hooking up that special OTG cable?
[Galaxy S III Accessories] scarrmrcc:
NO, as has been stated in this thread:

it is not possible with the current hardware and software on the phone. change pins, and a custom Kernel and it is possible... or find the magical resistor value that turns both on (if it exists.)

ATM you can have MHL, OR OTG, not both.
[Galaxy S III Accessories] Tularis:
Did you check the pinout with a multimeter?

I'm getting a cheap 5 pin MHL adapter. I will try to split it up and check if it also uses a resistor. If so the 5-to-11 adapter's resistor and the one inside cheap MHL would be in parallel leading to another actual MHL value. I will try to check ASAP.

I'm also trying to build my onw custom dock, trying to include (Obviously NOT at same time):

- Stereo audio out

- HDMI out

- USB OTG out

- microUSB (charge/data sync...)

It would be controlled using a slider switch at the back which will select the operation mode.
[Galaxy S III Accessories] harryville:
This would work as the phone gets power via the MHL port on the tv, this would then free up the usb on the adapter for OTG
[Galaxy S III Accessories] scarrmrcc:
no it wouldn't.

read the whole thread. there are missing connections, and switching issues.
[Galaxy S III Accessories] jmarkoa:
I don't think harryville is talking about the same 5 pin adapter that you still keep referring to. There are no missing connections, and therefore no need for switching, in the correct 11 pin cable. Upgrade your cable and re-try your tests.

---------- Post added at 10:29 PM ---------- Previous post was at 10:08 PM ----------

Yes, finally someone else who can see why this should work! Please help to solve this issue...

Just to clarify, using an 11 pin cable, half the connections should be dedicated to the HDMI output, and the other half should be dedicated to using USB OTG. I suspect the reason no one has gotten this to work is because no one has tested the correct setup using an MHL compliant HDMI port. These special ports provide power to the adapter and the phone, and so most likely, also the USB OTG port. So, once that is tested and established, it should be easy to figure out which HDMI port pin provides the power. We can then simply splice an HDMI cable to provide that power, thereby making this setup possible for a non-MHL-compliant HDTV.

Surely there are more of you out there that see how this could work. My cable is on the way, so we shall see soon enough if this is a viable solution.
[Galaxy S III Accessories] Tularis:
The setup where the female micro usb is used for OTG is not working. I don't have any MHL screen to test but honestly, I hope Samsung is not waiting for us to buy a new tv just to use Usb/OTG at the same time...

I first just want to know the pinouts to understand how mhl works on the usb side.

Enviado desde mi GT-I9300 usando Tapatalk 2
[Galaxy S III Accessories] scarrmrcc:
that is the "switching" part I spoke of.

pin4 of the USB is used to "turn on" MHL, and it is ALSO used to "turn on" OTG.

that pin is the key, and the firmware is set to do different things depending on what it "sees" on that pin. as of now, no-one has found a resistance on that pin, that gives OTG and MHL. and that is why we need firmware/kernel guys in on this. the hardware is easy enough. I do think i might get an 11 pin, full fledged s3 MHL adapter, to tear apart next...

I must take my cables and visit the local electrical store to see if they will let me play with an MHL enabled tv :)
