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.

Hello I got a USB gender change: A-Female to A-Female so that i could connect a self powered USB Hub to my Archos.
So far i have connected a self power Hard Disk directly into my Archos 70.
Didn't pick it up.
A mouse in the USB Hub.
Didn't pick it up.
A pen drive directly.
Didn't pick it up.
Is the Archos 70 locked down or does the USB Micro B connector they have on the Archos 70 work different?
I thought USB was a universal connector!
... one thing you have to realize is the device needs drivers to work those devices. you just cannot flip flop the connector and expect everything to work. tipically unless the device has a INPUT port which is a standard usb port not a micro or mini 5 or an old 1.1 usb connector it wont work.
Alot of those hongkong micro a to b converters are rubbish.
The nokia has been reported to work.
You need a USB "HOST" Cable, it contains a chip that puts your devices on "master" mode.
The Nokia and Archos one work, for the others don't expect them to work at all if they do not mention to be USB "HOST" cables !
BTW, the feedback is not very good, seems that it can deliver only 200mA, so if you want to plug an external disk drive, make sure you have a power supply on it before
Also some USB keys need more than 200mA so they won't mount at all :/
I found this: http://www.kjell.com/content/templa...9&path=97000000,119000000,149500000,151500000
Translation: Used by for example mobile phones with USB host (it's own built in USB controller).
Is the USB "HOST" Cable the same as this? http://en.wikipedia.org/wiki/USB_On-The-Go

That cable doesn't look correct.
[correction - that cable at kjell looks correct for hooking two USB On-The-Go devices together. So if you wanted to hook your Archos to another Archos or to a blackberry.]
Look for a micro usb Nokia n810 host cable. Or "Micro USB Host OTG". They seem widely available in the us on eBay
Usually they have the micro USB male connector and a full size female connector on the other. Be careful because some are mini USB, you want micro USB
Look on the us eBay for a picture.
Here is a pretty good picture also - http://www.dealextreme.com/details.dx/sku.51045 several people have confirmed this one works.
Yeah, the connector is obviously wrong on that one. I was mostly curios about whether this USB HOST cable was the same as an OTG.
That's the only cable of OTG type that I've seen in any retail store in Sweden (although I haven't been looking for it until now), so I was thinking of maybe getting it in the store and then get an adapter for the connector. But since there's a special pinning on these cables (as I understand from the Wikipedia article) maybe that doesn't work?
I'll probably go for the Nokia cable anyway, just to be sure, should be able to find it in a retail store somewhere...

this works fine on my 32IT. I can use my microSD adapter, camera, powered hard drive, multi-card reader with SD cards and USB mouse. Other people have said they can't get USB host to work at all, even with this cable, but it works for me.
USB mouse works ok.
But it`s not enought power for 3G USB dongles.... Печалька.
Nokia ones works ok

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.

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!

Has anyone made an OTG cable for the TFP? I don't like the chunky USB OTG connector and thought an OTG cable would be much better.
Not quite sure what you mean.
The only proper usb connector is a standard type A connector located on the keyboard, it has insufficient pins to implement OTG. The only other usb connectors are the propriety asus ones, one on the tablet and one on the keyboard, the other small connector on the tablet is HDMI output
I have the "chunky" USB OTG connector as well.. I don't think there's a cable though... I looked everywhere on the net
I don't have a dock therefore the only way I can plug a USB flash drive, Keyboard/mouse into the TFT is via the ASUS USB OTG Host adapter View attachment 1384503
I was after something a little slimmer and believe a OTG cable would be ideal - Refer to picture for an example of what I'm referring to View attachment 1384504
Micro USB OTG cables can be used with many phones and tablets sporting a micro USB connector. The TFP obviously doesn't have a micro USB connector therefore I was hoping someone knew how to make an ASUS 40 pin to female Type-A plug which replicates the ASUS USB OTG Host adapter.
Has anyone pulled apart the ASUS USB OTG host apapter? What's inside it?
Hey guys. There are several articles and videos around on how to make your own OTG cable. It essentially involves shorting a single pin. I have no idea if it'll work with a TFP, but I'm going to give it a shot today or tomorrow if I get some time. My plan is to use the normal TFP USB cable, but plug it into a female/female USB gender changer that has been modified to short the pin. I'm almost positive that it'll work on my SGS3, and I don't see why it wouldn't also work for my TFP. I'll report back.
Nevermind. I now see that the TFP USB end has five pins, so they won't match up with the 4-pin female USB port. Oh well...
TFP and OTG
Does anyone know if the OTG will support a USB hub?

The TFP doesn't have OTG, it's a regular USB host.
So yea, it will support a hub because it's a standard USB device class, with its driver already part of the kernel.
