[Q] Questions About MHL Adapter & OTG Cable Working Simultaneously - Galaxy S III Q&A, Help & Troubleshooting

Hi everyone,
I have an unrooted Samsung Galaxy S3 GT-i9300 on T-Mobile (UK). Running firmware 4.3.
I have an MHL adapter that works perfectly. I also have an OTG cable that also works perfectly.
I wanted to be able to connect my PS3 controller and display the game on my TV, so I bought an adapter from eBay and after plugging it into the phone and connecting the power cable, it simply charged the phone and the phone didn't recognise that the HDMI cable was plugged in or the PS3 controller either. So I got a refund and purchased the official
Samsung Multimedia Smart Dock(also from eBay)which is compatible with the S3 and it was exactly the same result as the cheap adapter I bought. The Smart Dock didn't recognise that the HDMI or the controller, it just charged the phone and nothing else.
Does anyone know why this is happening? For me, it doesn't make sense because the MHL and OTG cable work fine separately with their own individual adapters, so I can't see why they can't be connected simultaneously. Does it have something to do with the 4.3 update?
Can anyone please shed some light on this issue?
Thank in advance

Pair the controller to your phone via SixaxisTool so that it can connect wirelessly, and then connect it (your phone) to your TV via MHL. It works for me.

TV Out - how to enable?

Hi,
Noob question...
I bought myself the MHL USB Adapter. I want to output my SGSII to my TV. I tried the obvious and plugged in the adapter into the phone along with the HDMI but nothing happened.
Is there something I need to enable (i.e. when connecting a laptop to a project, you have to press Alt+F4 to change output)??
BTW I am running the latest Cyanogen Mod (update-cm-9-20120606-NIGHTLY-galaxys2-signed).
Only stock Samsung roms will work.
Cm9 official problem list stated same, you should have seen that first.
I bought the cheapest mhl adapter of eBay. The adapter is powered and came with a mains power supply ( a micro USB supply like the GS2 itself) and a vradle . I have to power up the mhl before connecting to the HDMI socket on the TV. Otherwise there is nothing to set up or switch on the phone, it just works, you get the beep and the connection icon in the status bar at the top, like when connecting to a pc by a cable.
I use it to watch rented films from the play store. It gives a very good picture on the TV.

New MHL and USB OTG issue

I've got a new MHL cable and a USB OTG cable in the hope I could plug my MHL into the SGS3, use a powered USB hub connected to the Micro USB(as this requires independent power) on the MHL and then connect a keyboard and mouse into the USB hub, then connect the HDMI to the TV.
For me it doesn't work. I thought this was the whole reason they changed the MHL cable to the new type. Can anyone else confirm?

I dont think Hub will work on the phone, I am not sure....
Anyway GS2 MHL no longer will work on SGS3, Samsung has released seperate MHL for SGS3, which are available in the Market,
I bought it and tested, working fine for me...

i am planning to get the MHL for S3, if i connect it to the TV, are usb drivers needed in order for it to function properly?
thanks in advance

Afaik the S3's MHL-Adapter is self-powered and does no longer rely on an external power source to operate. (Hooray!)

No, that's a pure HDMI adapter and thus Plug&Pray
Make sure to get a MHL adapter for the S3, the adapters for the S2 and other devices are not compatible to the new pin layout.

[Q] 11 Pin MHL + USB OTG

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:

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!

Connecting S3 to TV and using USB OTG simultaneously

Is it possible to connect an unrooted S3 to a TV via MHL and also plug in a PS3 gamepad via a USB OTG cable at the same time?
Maybe there's a cable on the market which allows this?
There is docking station made by Samsung, EDD-S20EWEGSTD that allows HDMI and OTG and charging simultaneously

Thanks, that looks pretty smart. It is pricey though!

USB hubs...any good recommendations?

I would like to buy a cheap USB hub to host my mouse, wireless Xbox 360 controller receiver, and MHL cable. I know it probably needs to be powered to function. Anyone have this setup yet?
On that note, I already have the MHL cable, and it seems random whether I need to power it or not...what's the deal with that
Thanks for the assistance:good:
Anyone?

I just bought this one which seemed to be a good deal.

As for MHL is this the black (1.0) or white (2.0) adapter. The genuine one's don't need to be powered when connected to the N3 but there are an alarming number of fakes out there.
