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

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.

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 ;-)

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
I want to attach two usb devices to my Note.
One will be the MHL adapter and one will be the 2.4ghz wireless unit for a keyboard like this http://www.ebay.co.uk/itm/250996855143.
I need a Micro USB male to 1x Micro USB female and 1x USB female adapter.
These for some strange reason don't exist
I was just wondering if anyone has done anything similar.
I know I could get a Bluetooth keyboard, but I don't have one. I do however have the above keyboard
Oh wow! I'm interested into this keyboard! Does Lenovo Mini Wireless keyboard work perfectly with the Note? All buttons are recognized and trackball mouse is usable?
Its really good, i use it on my Note and my Libretto W100. The mouse and keyboard work perfectly.

You cannot attach 2 or more devices to the same usb port. You need an usb hub for that, but I don't know if the MHL would work with the hub. I will try later today to attach an usb hub and connect more devices, and will report my findings.

Edit:
--------------------------------------------
I have successfully connected a self powered usb hub to the galaxy Note, and connected 2 thumb drives, a combo card reader, and a mouse. The Note mounted both of my thumb drives, as /usbstorage/sda and /usbstorage/sdb respectively. Then I inserted a mikroSD card into the card reader and the phone mounted it as sdc. I then inserted an sony memory stick into the card reader and it was mounted as sdd. All mounts were usable, and I could watch movies from them, and watch pictures, copy files from one to the other, etc... But, when I connected the mouse to the usb hub it didn't recognize it. Whatever combination I tried the Note would not recognize my mouse, when plugged into the usb hub. When plugged directly to the OTG cable it works perfectly, but won't work when connected to the hub (maybe cables are to long).
Using rooted stock xxla6 firmware.
Edit2:
---------------------------------------
Just found out, that usb otg and mhl cannot work simultaneously. When the MHL cable is plugged in, the GNote's microusb port will become an MHL port, and from that point it will not act as an usb host or usb slave. :-(
It's too bad, 'cause I really wanted to connect it to my full hd monitor and use a mouse and keyboard, too.

How about bluetooth mouse+keyboard instead ? That would keep your USB port free for MHL

This is the setup I'm going to do also. But as with topic, it's also very tempting to have everything USB powered. Since it will decrease latency and maybe power consumption as well? (as opposed to bluetooth) Well, MHL to HDMI will still drain our battery even if we connect it to power source
You can also try NZtechfreak's workaround:
http://www.androidnz.net/2011/11/samsung-galaxy-note-connectivity.html
Hopefully somebody who has htis can shed some light on it.
If you're using MHL hdmi out, the unused micro USB port on the adapter needs to be fed power, correct?
So does that mean that if you're outputting via HDMI that you cannot utilize the USB OTG? Or will you have to use a powered hub to simultaneously drive the HDMI output and the USB OTG peripherals?
I don't think it will work like that. I tried plugging my OTG cable with a powered usb hub into the micro USB port on my MHL adapter. Even without an HDMI cable connected my phone would not detect my wireless mouse and keyboard.
Are you using the official mhl adapter?

Weird, the whole point of Samsung going with the 11 pin was to enable USB OTG. Maybe it doesn't work with the adapter?
I guess I'll find out, the official adapter is in the mail, should be here Thurs.
Of course it wouldn't work with the adapter and an older cable. The adapter is only rearranging a 5pin power cable and hdmi to match the 11pin in the phone. 6 pins in the phone are still not used.
If I remember ill try it with the official S3 adapter later.

i also really want to know if the samsung 11 pin (not adapter) will work with a powered USB hub and OTG ..

basically what I want is a OTG cable that splits off to a regular mini USB as well.
what I'm trying to do is be able to plug my phone into the charger and be able to plug In a ps3 controller into the note 2 as well.
I know I can do this wirelessly because I already do this. But what if I'm gonna charge my ps3 controller and my note 2 at the same time?
the only way I see you can do this is taking USB OTG cable and then connect that to a USB Male to male. Take the one male and connect that to usb to adapter that splits into 2 males. One of those males will go into the charger and the other will connect to a USB mini adapter and connect ps3 controller to the mini adapter.
Sounds very confusing but sure if it work between all that.
What would be easier if they had a micro USB splitter that splits into a USB adapter and a mini USB.

That makes sense haha but here's a question can I use a 4 port usb hub to connect my charger to it to charge phone and connect mouse and keyboard as well as ps3 controller? Or do I need a hub with ac adapter?
Or will it not work? The usb connected to the wall charger connected to an adapter to the hub?

I don't think it will work, the dock achieves this, probably by informing the phone that it's a dock, but the adapters rely on shorting the ground wire to tell the phone it needs to become an usb host. I don't have empirical data but my electronics training tells me the power supply (charger) wouldn't love a short on it's grounding and wouldn't charge the phone...also when going into usb otg mode the phone supplies power, so the charger would see this as a short or an over current situation and not charge.

because both mouse and keyboard would be using through Bluetooth adapter. i already use the mouse and it works through the regular Samsung otg cable.
Can that just work off from the Note 2's Power Supply?
it can only power 1 device, and barely. it outputs around 300mA which is enough for a usb stick, a mouse, a keyboard, or a controller, but not for external hard drives nor other phones your usb hub would have to be powered our else you may suffer reliability and connection problems with your keyboard mouse and controller. basically if you pressed a button on all three the phone would lose them all momentarily

1 thing is that it's 100 dollars. second thing is basically I can't put in horizontal mode if I want to use a keyboard and mouse and browse the Internet I don't want to browse it straight up and down. not to mention if I want to play games as well if I'm using ps3 controller to charge it at the same time I can't do that. who wants to play games tilting their head to watch because of the fact that the phone is mounted vertically instead of horizontally.
I mean I don't understand why it so hard to find a micro USB to a dual USB adapters I mean that shouldn't be that hard to make haha. with that I can use a keyboard and mouse using Unifying receiver. and then the other USB adapter can go straight to the ps3 controller.
So it would be called micro usb male to dual usb female

here's what I don't understand if I take that USB hub connect it to the adapter that I have, and have the USB Bluetooth and keyboard bluetooth in there at the same time, I shouldn't have issues because if im browsing the internet I'm not going to be typing keys on the keyboard and moving the mouse at the same time. so in theory I can move the mouse around Lets say go to the address bar stop using the mouse and go to the keyboard and start typing on the keyboard. so basically I will only be using 1 port at a time. instead of moving the mouse and typing keys at the same time I won't be doing something like that just be ridiculous haha.
so can I use that Belkin USB 4 port and just basically use the two USB Bluetooth hooked up to it. so the port will be connected to the OTG cable. if this makes sense I'll connect the OTG cable to the hub and the 2 Bluetooth to the hub
because if I honestly wanted if I wanted to play video games like grand theft auto I can use the keyboard to type cheats and stuff. use the keyboard through the OTG cable. and connect my ps3 controller wirelessly.

wowowow, no, keyboard, mice and ps3 will only be afected if they are wiered or rf. bluetooth devices wont interfere with each other, you can have a ton of devices on bluetooth and not even need the usb otg... you dont need a buetooth adapter for this, phone, it comes with bluetooth, so any bluetooth item should work with the phone while it's charging without needing the usb otg cable at all. ps3 controllers are bluetooth by default. you dont need to plug them to the phone.
