The most Micro USB to USB converters are not work if you want to use it for OTG converter, because the 4. pin of the micro usb plug is not connected!
The most ebay and computer shop's converters like this!
If you want to use it for working OTG adapter you have to connect the micro usb connector 4. pin to GND (5. pin).
Like this:
I made this mod on my adapter and it works!
First you have to open up the outter cover and carve the plastic around the micro usb pins. You can use multimeter to check the pinout.
After that solder the 4. pin to 5. pin with a piece of wire.
And finally glue back the outter cover.
Video:
So if you have not working adapter you can mod it, if you have suffice experience with electronic and proper tools.
Only do with your own risk!
I have this Usb converter!
With your mod works perfectly!!
just tried it it works perf, thank you!
Weird I got one off eBay from Hong Kong and it works without Modding. Can open files off a USB stick. Got it for £1

I buy a pair in Dealextreme.com
SKU 50774 o search OTG
It may have a resistor between pin 4 and 5, kind of like a jig,
I remember there was a fun with resistors thread for the sgs1.
I may attack tge free dock I,got from optus.

OTG Cable USB (B) to Micro USB (A) Powered with AAA batteries ?
As one knows, Samsung has promised a MHL Cable
You noticed it is not only a cable but a box out of which you may plug in an extra power supply.
The obvious reason is if the passive monitor does not furnish 5V, the phone will rapidly be out of power.
Now you know that to obtain video rather than anything less, Pin 4 (sense) and 5 (Ground) of micro USB (male A) must be connected with a 365K resistance.
I suppose the dock Samsung is selling for I9100 (yes, I have it) is grounded at 1000K as it provides audio with remote, and yes, the dock provides power supply via extra micro USB as well.
I come to my point: If I want to access any USB data On the Go, I need a cable OTG with 2 ports: USB 2.0/3.0 (female, B sided) to a micro USB (male, A sided, grounded but with no resistance = 0K). Many of them exist on the market out there.
But it is quite impossible to use because of lack of power supply in the passive device (let’s say a handy 1T HDD usually powered via Host connexion !
Would it be possible to insert some sort of receptacle for AAA battery in the middle of such a cable to provide for power while you are for a long time out of access to an electric plug ? Does such a cable exist somewhere to buy ? What would be the sheme to mount this ? HELP !
Is it possible to add USB charging cable to USB-host cable? I want to use mouse\keyboard\flash and charge device in the same time.
I also interested how to add power to USB-host cable for devices "High-power device connected".
OTG and Power
thats excactly my question:
is it possible to use otg cable with a trackball or mouse and at same time charge the S2?
give power to usb mouse and charge S2 over a charger!?
Is it possible to use a game controller over usb otg? Would be pretty nice.
Wanna have a S2Play ;-)

i do have same problem..is there any suggestions to make sgs2 can read the high-power USB flashdisk via otg??
An USB hub with external power maybe ? I didn't tried this kind of setup, but it should work. I have a hub, but I don't have a OTG cable yet.

I've been try this, but still doesn't work for me..I'm also used electrical multi-tester, and the usb flash already has 5V voltage but in my sgs2 still nothing happen (my usb flashdisk doesn't mounted to sgs2)..
Is there any driver/apps do I need to install first before using OTG?? or, is there two kind of sgs2, the one which support OTG and the other one not??
please someone help me...One point I choose this SGS2 is the OTG feature..
PS: sorry for my english
Has anyone found a MHL cable that also includes a USB OTG port? Samsung reportedly changed from a 5-pin configuration to an 11-pin configuration to allow MHL with USB Host mode simultaneously. Perhaps for a future Desktop Mode?
Has anyone been able to find one of these cables?
Just wanted to update, I believe I found the type of connector that I was looking for, but it is missing HDMI and it is sold out. This essentially could give you PC type connectivity on the S3.
http://www.mobilefun.com/35462-mobile-fun-connection-kit-for-samsung-galaxy-s3.htm
I think we still have a bit of a wait. What you found is essentially a USB OTG hub with some card readers built in. I seriously doubt this will pass through the pins for HDMI to work out of the usb port. We'll see something when this phone finally launches everywhere. It's not even out in the US officially yet
EDIT: Sorry, didn't see the article in the link in the OP. Man.. I might have to get me a GS3 now. I'm quite satisfied with the reasoning for a pin change. =)
Samsung sells 11 pin MHL adapters and USB female to Micro USB male adapters on their accessories page, but I'm not sure if you could piggy back the USB input into the charging port of the MHL cable. I don't see any all in one cables on their site, and the desktop dock is just micro usb/audio. I tried.. =(
Here's what I was looking at.
Old and mostly unrelated. See edit.
I happened to buy what looks exactly like that adapter today earlier at Micro Center. Now, I do have a Galaxy Nexus, but the USB OTG works great with keyboards/usb/mice/hubs; however, I cannot get it to simultaneously work with my MHL adapter. I understand the GS3 has a different pin layout though for MHL - my phone works with my MHL adapter correctly, but I didn't think it would have any change on the USB OTG. I'll most likely be breaking these apart and start tinkering. My goal is to show people how much of a full desktop-like experience I can provide from my phone, since so many people somehow think a GNex or GS3 are inferior to tablets, just because they're smaller... lol
Good luck finding information out on some kind of MHL/USB OTG setup. I'm just trying to provide any information I can from how my situation works with MHL/OTG, since I'm currently on the quest to achieve this myself.

I'm not really sure why people think they NEED MHL and USB OTG simultaneously to get a "desktop-like experience". You can already accomplish this with just a plain MHL cable and a bluetooth keyboard and mouse as was demonstrated in the Connectivity Demo video on youtube.
Edit: Actually I just remembered about portable hard drives. If you want to hook up a mouse, keyboard AND hard drive I wonder if you can plug all three into a powered USB hub connected to a bluetooth dongle. Hmm...
I'm looking for a dock with USB OTG, charging and MHL. Maybe some day.
I believe this is already capable. Everything I say here is purely speculative, but what I see is that Samsung moved to a 11-pin connector for MHL and the standard 5-pin is no longer functioning. To call it MHL, they probably have to use the same standards for data encoding... but they simply "moved" the pins.
I put "moved" in quotes because of the way in which a standard 4 pin USB cable works (or 5 pin for our case)... you have a +5V, Ground, Data + and Data - (one data to phone, one data from phone, carrying ALL data). Since our phones still sync via 5-pin cables, this means the 5 pins are still "hot" for data like all other phones. I am presuming, that for the 11-pin connector, Samsung simply added a few more data+ and data- connectors (much like having two or three USB ports on a normal computer) but consolidated the ground/5V reference. I could be wrong, but it would make sense.
Lets call the stock 5 pin data connectors (2 wires) USB1. This is where MHL is conventionally sent through and all sycing can be completed through, 5 pin cable or 11 pin cable. If samsung added two additional USB ports to the single connector, lets say MHL is now over USB2 (wires inaccessible to 5 pin connectors). This frees up bandwidth and COM ports on USB1 and USB3 to use for accessories like a USB hard drive and keyboard/mouse. On a 5 pin connector, however, only USB1 is accessible. The Samsung 11pin to 5pin MHL adapter simply moves the data+/- from USB2 to USB1 (standard 5 pin location), so with the adapter you are syncing/exporting video over USB2 on the phone with a standard 5pin cable.
My thinking is such: If you plug in the OEM 11pin MHL adapter, it will also have access to the standard 5pin USB1 connection. Since USB2 is used for MHL, you can then plug any OTG device into the micro USB connector on the MHL adapter to make use of it. The only problem here is power (or lack thereof). By plugging in a USB hub with a discrete power source, plugging this into the MHL adapter, and plugging in the USB device of choice into the HUB, you *SHOULD* be able to get simultaneous data and HDMI. This assumes they put the standard 5 pins to the connector on the side of the MHL adapter and only wired the HDMI to the USB2 area.
Alternatively, you *SHOULD* be able to plug the micro USB cable from the MHL adapter into a computer, and simultaneously be able to sync files while outputting HDMI video. It sort of just comes down to being able to provide power to the MHL adapter on the +5V pin while using the data pins to access the phone. As soon as I have my MHL I'll figure it out, but that could be a bit. If anybody has access to a pinout from a Samsung 11 pin micro USB that would be helpful too.
Again, just dreaming here. I don't know anything about this, but if I was the engineer at Samsung I would choose this over analog outputs like Apple used for their giant connector.

for me at least i already have several keyboards and mice ... none are bluetooth.
I'm looking for the cheapest option available.
I'm just hoping someone releases a cable with 4 plugs:
Male MHL - To Phone Obviously
Female MicroUSB: To plug in charger
Female HDMI - To Display
Female USB - To USB Device
That's all I want... should cost less than $2 to make, just sell it for $20 and I'd be happy.

hi v8bait, are you able to get data thru the micro usb port at the side of the 11-pin mhl adapter? i was thinking of using the motorola lapdock with my s3 thru the mhl adaptor (other then a micro hdmi male connector, the lapdock also has a micro usb male connector that apparently send out power as well as push keyboard/trackpad data upstream) - if it works, we can have an inexpensive "clambook"
Just to recap,
Will this we possible:
Official MHL adapter -> hdmi to monitor.
|
>OTG cable> Powered USB hub> USB keyboard & mouse.
In other words, the PC Experience with a keyboard and mouse.
Dont really want to spend the money to buy a Bluetooth keyboard and mouse when the USB ones can work just fine (theoretically).

I am also very interested in this exact thing. Using USB devices (multiple ones, e.g. plugging a powered USB hub into S III and then plugging them in) but also putting out S III video to HDMI.
However the other workaround is using AllShare Cast. In fact that is the route I'll likely go, because of the other unique advantages of AllShare Cast (i.e. using it for presentations to screens, etc.)
So: has anyone plugged a powered USB hub into S III and used multiple devices? Such as a keyboard and mouse?
I also want to use this S III more as a computer. the other perfect thing I wish I could buy would be a keyboard case, like the one available for iphone, so I can prop the S III up on a kickstand and use a real mini-QWERTY physical keyboard.

We're in the same boat; i want to use the s3 like a mini computer too. I think it'd be great for business travel, when i dont really need a laptop during the day but want something when i'm back in hotel room. I'd much rather use hotel TV instead of a laptop because that's what i am used to at home... pc hooked to TV.
I've been planning to use the allshare cast dongle too, but they dont seem to be available yet. I was thinking HDMI out with the allshare.. charging with the wireless charging kit and then keyboard and mouse with USB OTG. My logitech unifying receiver for keyboard/mouse works perfectly i just need the wireless charging and allshare dongle to be released.
For what it's worth I tried a powered USB hub and could not get it to work with the s3.

Wait so your saying you tried a (a) powered USB hub with a OTG cable connected to the phone or you tried a (b) powered USB hub connected with a OTG cable to the MHL adapter and then to the phone?
If it was (a) then there are some vids out there of ppl using powered USB hubs.

Very interested in this.,,
I'm puzzled that there aren't any more postings about this kind of stuff. I was expecting the GS3 to be easy to use as a "PC" replacement but it seems no one besides us few wanted to do that ? A simple cable should have done it but I'd even be willing to shell out 40-50$ for a decent dock that would do just that

You are not reading it right.
they want to use the MHL adapter, too.
As far as i can tell, the MHL adapter needs to be in the phone, not a hub. it is all dictated (the output being OTG, or MHL) by the impedance of what is plugged in. It is an either or situation.
Perhaps with a firmware update they MIGHT be able to run both signals and split it.. but i doubt it.
I use USB OTG pretty often and I want to be able to charge my device while using it for other things. Is there any type of splitter from microUSB (Male) to USB 2.0 female + microUSB female OR from microUSB male to 2x microUSB female?
