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 ;-)

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
Ive since moved on from the atrix but kept the lapdock to see if i can use it for a hdmi monitor and charger. I now have the galaxy nexus and wanted try and use the lapdock with it. Im going to order the MHL adapter for the galaxy nexus to connect to the lapdock's hdmi with a female micro hdmi adapter. Ive read that the lapdock can receive HDMI input from other sources besides the atrix but will the lapdock accept HDMI source from a MHL adapter. Another problem is that in order for the Samsung MHL adapter to work it needs to be plugged in to a micro usb power source. I need to be able to use the micro usb from the lapdock if i want this set up to be portable.
i bought a micro usb extension and tried that but it doesnt charge galaxy nexus or Optimus P500. Unfortunately i sold my atrix before i got the cable so i cant test it with that but the micro usb extension charges all my phones fine when plugged into an AC adapter. So is it possible to mod the lapdock or micro hdmi cable to charge my other phones?
I can't speak for different phones made by different manufacturers (samsung, etc), but the atrix lapdock can be modified to work with other motorola weptop enabled phones. I am typing this on an atrix lapdock plugged into my Droid 4. I had to modify it when i bought it in order for it to work, but it was a simple 10 min job and it has been working well!
All I had to do was unscrew the cover of the hdmi/microusb ports, and flip over the connectors that were upside down for my use, and put it back together. A bit of shaving the plastic in the corners was necessary, but was not difficult. I am a happy user since this keyboard is a bit larger than the lapdock 100, and it was cheaper on craigslist than a lapdock 100.
Now I just need to see if anybody has managed to find any happy ways to hack/modify the atrix lapdock for greater functionality, like multitouch or scroll areas. If you have happened to see someone getting this to work, please do tell!

no need to mod!!! there are two powered usb ports on the back of the unit. when it senses hdmi, it turns on the usb ports and you can charge or power your usb device assuming 500ma is enough. not sure what it outputs, but it does charge a phone.
Where i can buy the lapdock charger?

Have you tried it with a usb pen connected. I think it won't charge when no usb device is connected.
I believe its not possible to charge while using otg mode, as the phone's charging capability is blocked to enable otg. Im not sure if charging through pogo pins will work or not, but it should.
And I believe power part of the cable you purchased is for external power to your USB device, like a 2.5" external HD.
Hey guys,
Bought a used HTC One due to BT connectivity problems with my SG4.
I have a requirement to use MHL daily and need an adapter that will allow "AC" chargiing mode. I am using the same charger as I did with my SG4 that did provide enough to actually charge the phone while using MHL.
The same usb charger running through my current MHL 1,0 adapter into my HTC one, will only put the phone into "USB" charging mode. This is not adequate and will probably force me to sell the phone off.
Here's the MHL adapter I am using:
http://www.amazon.com/gp/product/B005F9W6DU/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
Do you guys know of a MHL adapter for our phones that will allow AC charging mode?
I don't use mhl but a kernel that supports fast charging comes to mind.

What do u need mhl for anyways?
I have the rocket fish mhl cable. I have hooked it up to my tv to watch NFL Mobile plenty of times. I plug my phone AC wall charger into the MHL cable as well to keep the phone charged, however, the phones battery life does not increase. So say, my battery is at 75% and I plug my mhl cable into my phone into the tv and my 1 amp power charger from my wall into my mhl cable to charge my phone, even though I get the charge status, two hours later, three hours later, my phone is still hovering around 75%. I hear it takes a lot of power to run mhl cables from the htc one to a tv. I hope I helped you with any information that I provided.

Actually, some MHL adapters can charge the phone and do HDMI. Mine does.
I have a cheapo Samsung one.
Unless OP is referring to something different?
Hi all, new user for galaxy note 10.1 2014 version.. thanks for the threads, very useful info..
As I have trouble finding the Samsung compatible adapter through amazon or ebay in the UK, should I assume that any 11 pin HDMI adapter is compatible? should I look for adapter for Galaxy note 3 or the Galaxy S3?
Thanks a lot!!
Look for the mhl 2.0 adapter from samsung. It's branded "for galaxy s4/s5". Just make sure it's mhl 2.0. I have it and it works very good, outputs 1080p/60fps and it works without connecting power.
looks like this: http://www.samsung.com/us/mobile/cell-phones-accessories/ET-H10FAUWESTA
Thanks for the prompt response Clouds5..
I have trouble finding that specific adapter you posted.. even Samsung has run out ..
However, I find many cables with s/n ET-H10FAUWEGWW... The one you have posted is the ET-H10FAUWEGUJ.. Should I assume that these adapter are the same? I am in the uk, maybe this is s/n for the international market? Essentially anything in the ET-H10FAU family is the same, provided of course that it is branded as MHL 2.0 adapter and suitable for galaxy S4/5 as you point out?
Thanks..

Look at Amazon.uk for Samsung MHL 2.0 and pick a geniune one. Alot of fakes around and read the comments. Reak MHL 2.0 dont need power source and fakes ones needs.
ex might be real: (read comments)
http://www.amazon.co.uk/Samsung-ET-...d=1397297202&sr=8-63&keywords=Samsung+MHL+2.0
Might be fake: (read comments, delivered from China = mostlty fakes)
http://www.amazon.co.uk/Genuine-Sam...id=1397297537&sr=8-2&keywords=Samsung+MHL+2.0
I did bought a cheap MHL 2.0 from ebay, seller was from China and it did works for a while. It also needed powersource to work, after a while and aspect ratio become weird. So it was a fake one for 6 US only.
Decide to buy new one from mine country and it didnt needed any powersource connected to MHL 2.0 adapter. It was cheap, just 20 bucks deal back then and also described for Galaxy S5, even back then S5 wasnt even announced and lucky it was genuine from Samsung.
Real and fake have different weights too. There is a thread about real vs fakes MHL 2.0.
http://forum.xda-developers.com/showthread.php?t=2412756
The fake from ebay I bought was indeed around 26 gram and real one with 20 bucks deal weights 42 gram.
Thank you dt33.. I have just ordered the adapter you pointed out - I had it already in my Amazon basket assuming that it is a genuine one..
I also read the thread about genuine/fakes.. looks like that unless it comes directly from Samsung, then it is a gamble..
I will test it, weight it and report back with the s/n.. hopefully it will help someone facing the same problem.
Thanks,
Achilleas
I bought this one per recommendation of another XDA user. Works as it should for now.

All good
To complete the thread and potentially help future buyers from the UK....
I bought the Samsung ET-H10FAUWESTA which turned out to be the ET-H10FAUWEGWW... bottomline: all the genuine variations of the ET-H10FAU cable seems to work for our model.. and no need to be plugged in so all good..
Thanks all for the help.

the HDMI cable works without the wall plug.. just with the tablet's power..
if you use the wall plug then it will charge the tablet while the HDMI is used...Is this what you are asking?

I have trying to find one that will charge the tablet at the same time you have the tablet connected to a monitor though an HDMI cable. Does the tablet (specifically, the Note 10.1 2014) show that it is in the charging mode when you are using this adapter with the wall plug? Thanks!

I have a HDMI adapter for my N7000 which I also use for my SM P-605 and it works just fine but does not charge my tablet while connected to my TV. After the kitkat update, (surprise! surprise!) it just decided to charge my tablet while connected to my TV.So probably it's a kernel thing.

Wait a second here. Are you saying that your tablet charges only through the mhl connector without being connected to the wall plug? If this is the case, it receives power through the hdmi cable?! This is really strange. I didn't know hdmi could offer the needed current for our tablet to charge!!! To be sincere I don't think this actually works. You probably need the wall plug to be connected to the mhl for it to actually charge the tablet.

It's connected to a wall plug of course, but before kitkat even with the " wall plug" connected it doesn't charges and now it does.
