Mhl + usb otg - Galaxy S II Q&A, Help & Troubleshooting

I have searched for a while and am wondering if there is a dock and or cable that will allow you to use USB host, access it, and play it through HDMI; while charging?
I can't find a cable that can do this... but what about a dock?
Thanks for your help.

Not possible. The SGS2's connector doesn't allow for simultaneous USB & MHL. When the MHL-to-HDMI adapter is plugged in, the SGS2 detects it (by measuring a specific resistance value across the two data pins) and switches to MHL mode, in which the three available pins are used for audio & video info, and are thus not available for USB data.

[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.

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.

[Q] S2+USBhub+hdmi+charging-what I need?

I want to have S2 with usb keyboard, mouse, (probably a pendrive/hdd also), and a hdmi screen connected while charging the battery. My question is, what cables/adapter and usb hubs would I need to achieve the desired configuration?
As far as I know, what you want isn't possible. The MHL/HDMI and USB are mutually exclusive -- they share a connector, and when the MHL/HDMI adapter is plugged in, the connector switches into MHL mode, and the USB data pins are re-purposed.
you can't, maybe a bluetooth mouse/keyboard will solve part of the problem. And maybe you can use a powered hub to use them together, but not with HDMI
The phone differentiate MHL, USB,USB jig, and charging mode (AC vs dc) via resistance between two of the connector pins on the cable. So one mode at a time.

[Q]USB On-The-Go passthrough for MHL?

In preparation for getting my Verizon Galaxy S3, I have went through all the features I need for a phone, and realized that the most important one features is not documented anywhere. MobileFun's "Mobile Fun Connection Kit," has connects via MicroUSB and uses USB on the go to process attached USB devices on the USB port. Is it possible to use the MicroUSB in the adapter with Samsungs official MHL adapter, or Adapter Tip (Meaning I plugin the the Connection Kit via microUSB, then attach a device(Keyboard, mouse, etc.) via USB port, then use the connectors microUSB port to attach the MHL adapter, transmit the video signal to the TV, and then use the MHL's microUSB adapter to power the device)to the Connector. If not, (Do to bandwidth issues, or generally insanity of the question), are their any alternative implantation's I can use? Are their any other on-the-go adapter with MHL and a USB port?

Specifically, MHL through USB on-the-go, or the galaxy S3's proprietary MHL implantation prevents it from working?

[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.

Micro USB to USB female adapter

I bought a micro USB (M) to USB (F) adapter so I could plug in my XBOX PC wireless game receiver into my LTEVO, which is intended to allow me to use my Xbox 360 wireless controller with my phone. However, the wireless receiver will not power up when I plug it into my phone. It works when I plug it into my PC, so I know the receiver is not the issue.
Is there a setting that I need change on my phone in order for the receiver to get power? Or do I need a different adapter in order for this to work? I've seen them work on the Youtube videos, so I know this is possible. I appreciate your assistance!
I don't think the microusb port supplies power to external devices??? Or if it does it may not provide enough to power the adapter. I believe that is why if you buy the MHL adapter for HDMI it only works if you plug your charger into it to supply power.

Valid point, however, check out all these Youtube videos showing the adapter/receiver working without external power:

I think for that to work the device needs to have USB-host capability (and have that capability enabled.) I don't know if the LTEVO has this, but I kinda suspect that it doesn't.
