Hello,
I own hdmi out reduction and usb otg cable. I wondering if it is somehow possible to work simultaneosly with connected hdd and tv over hdmi to make small media centre?
I tried, but not succeeded, because lack of power in one of these connections probably. Anyone have some advice ?

Nope, not possible. There is a USB switch behind the port that switches between USB and TV-Out depending on what is connected to the port. It will never do both simultaneously. See this post, and the links contained within. There's a video linked where a spokesman from the MHL consortium talks about it.

Has anyone figured out if its possible to use the ExtUSB (sync) port as a USB host port? I'm guessing the communication lines could be controlled with software, but that you would have to use an externally powered USB hub (or devices that are externally powered) unless the +/- charge lines are 2-way.

I don'ty know the answer, but... what for? The X7500 has the cable to allow USB devices connect to the USB host... so? And for sure you will need a cable to convert mini USB to female regular USB... so is not a matter of money or carring a cable I guess.
Mostly techie curiosity. I figured since someone already figured out how to reroute internet sharing to make a wifi host, someone else must have looked at that normal-looking usb port and thought about making it work like a usb host. I'm a programmer but I don't have time to work on that...

unfortunatly the chip that does that feature is not capable of that.
if you look at the schematics of a root hub it has 1 main chip that is the hub controller, and slave chips for each of the ports. a device interface has a diffrent type of chip that's intended to be connected to a root hub connection port. thusly no software fix could be made too convert a port intended to be a connection point into a root hub port
mind you the 4-in 1 cabloe is cheap enough and i saw at least 1 site via google that had a usb port only cable for the sepcial connector
so is worth looking at that.
Hey - do you have the details of the company selling this 'usb only' cable?
Thanks for the input. Just curious if it could be done, I hadn't tried to look up the schematics. I second the request for the info on the usb-only cable, that would be perfect since they already gave us a vga cable...
Would this "USB cable" allow me to use a 149GB externally HDD caddy like I managed on my Dell x51v Axim's CF to USB slot, as the 4 in 1 cable isn't cutting it?
Thankz
There are lots of posts related to external HD and X7500... in general most of them (99'99%) don't work properly. In the webpages from HTC said that the 4-in-1 cable only admit mouse, keyboard and pen-drives.
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.

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.

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.

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.

Could this phone potentially be able to charge, be HDMI out and be connected to a keyboard and mouse all at the same time? Or can you only do some of these features? I Saw the video of the phone being connected to multiple devices but how about everything all at once?

It cannot be connected to MHL and USB OTG at the same time, but you can do everything you mention with an MHL adapter (which has, and requires, a charging input in order to be able to use it), and a bluetooth keyboard and mouse.

So you're telling me that it can only do Video out or read/write to USB devices but can't do both at the same time?
The reason I ask is because I'm thinking of designing a board with its own power source so that it only requires to read information from the 11 pins to accomplish everything.
I want to charge the phone, have a few USB ports and a HDMI port and have the phone interact with all. I just don't know the specs of the board or what is going on. Maybe I need to get in touch with superico.
However, is there any way possible to charge your phone WHILE using the OTG adapter? They both use the 1 micro port on my phone, but I need to find a way to charge the phone while using the OTG adapter.....perhaps a micro USB splitter-type adapter?????
I was actually wondering about this myself, though I don't think a splitter-type cable would work. I'm wondering if the power connection is on separate pins than the data, though...if they don't share space then I'd think it would be possible in some fashion.

A similar problem is showing up regarding using the mhl port to output to hdmi. Though the original information indicated that the power cable was supposed to charge the phone it seems it does not on the first version (super DUMB).
I have read though that the newer version of the mhl port is 10 (I think) pins rather than the 5 of the original. The newer port DOES allow charging while output is in operation.
I suspect this will also allow an OTG cable that charges while in use.
I am not so sure about the mhl idea anymore. Only one port for everything is ok if it has enough pins/bandwidth to have a breakout box that would allow an external usb drive to be read while hdmi is being output to a screen and power is supplied to the phone. As it is now with only one-at-a-time it isn't very inspiring as the phones get closer to the power of laptops.
What would be really neat would be a box with wi-fi, and the output to hdmi and usb ports as well. A wireless breakout box. Then the charger could be over by the phone which is near the user.

I think this thread could solve your problem.
Oh... I found a useful diagram here.
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!
