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.
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'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..

you will not be able to plug in a USB peripheral (mouse, keyboard) directly into the phone. it will not work.
you can, however, purchase a +5V powered USB hub (that plugs into the wall), and use that to plug into the phone and plug your KB/mouse into the hub, and it should work. you can find such hubs at www.dealextreme.com
to further answer your question, USB-___USB converters will work as long as the converters have all four lines hooked up. many converters are 'power-only' where only the power/ground lines are connected and the other two lines (data) are not.
So if i buy an ordinary pc hub that connects to power and the plug usb-to-microusb, it will work?
Well let it alone, ill buy a Bluetooth keyboard, will spare time and cables and converters ahahha
The Micro USB plug must be OTG (USB ON THE GO) or your phone won't recognize the peripheral. Also the advice given was correct, the phone USB port can't provide power to a peripheral device and so you must use a powered hub in between the phone and the peripheral device.
A USB OTG has pin 5 and pin 4 tied together in the Micro USB connector end to tell the phone to invoke OTG mode.
Lordareon: yea... if you'd go the wired route, you'd need a powered USB hub, since the Atrix's micro-USB port doesn't work as a host port. It doesn't provide power to external devices.

I bought these on ebay. The HDMI is short but worked but when I connect both cables to lapdock, the USB is not being recognized so the keyboard/mouse is not working. I want this just to act as an extension so I can use full lapdock abilities with cables. Any idea what's going on (cable charges on plug but does not charge on lapdock)? Maybe someone has better usb cables.

i don't think it will work either way, tried a few things like this with no avail.
why wouldn't they? Cheap build quality that doesn't include the data wires? Hell I'll be willing to splice two cables together to get our desired effect, the only problem is that cords with a female micro usb are incredibly hard to come by
So that is what you think it is? No data on the usb cables.

the only reason that is my suspicion is because there are many "charging" products out there that don't really need data. Why there would be a need for such a small charging extension cable is beyond me, but it's the only solution I can think of, but I have no way of confirming or denying it either. The ebay descriptions seem to imply that the data wires are there, but we all know how reliable ebay can be...
Another idea I had was that it might be sensing the resistance in the cable, since, if I remember correctly, that was how some think/though the car dock puts the atrix into car mode without a magnet as is/was commonly used. Again these are just ideas.
Or the cable is just so poorly made that it's defective...I honestly have no clue
Has anyone got full lapdock capabilities using extension cables? I can only get the screen working and not the mouse and keyboard.
The HDMI extender was the hard one to find. There are other micro USB extenders out there, theoretically with all wires connected....

Kind of makes me wish i hadn't hacked up my lapdock to work with the Otterbox
Where did you get your HDMI extender? I got mine from All4Cellular but it's quite short. Will have to get another HDMI one if the usb cable you recommended works.

The HDMI certainly looks like it may work but the reason I didn't buy that product from ebay a few weeks ago was because it was $50. Now miraculously, it's only $6. Maybe I'll get that if the USB cable I just bought that was suggested works a few posts back.

The HDMI cable seems to work. On the lapdock, with just the HDMI cable hooked up, it functions like it was it's an entertainment center.
The USB cord will need to be modified a little bit. I can't get it to seat right on the USB jack of the dock. I'll need to shave it down a bit as it doesn't sit down snugly.

I ordered the USB cable and experience this same problem, though I am waiting for my hdmi parts to come in (by April 6th I should have all my parts...). The cable itself works flawlessly as a micro usb extension cable when connecting it to the computer.
again as mentioned in the other thread, you want to be careful with the 5v coming out that micro hdmi port. for connecting back to your phone would be no issue, as the phone charges using this voltage, but hooking the lapdocks micro usb up to a host device probably wont appreciate the 5v coming back up the cable, where normally the usb device would be pulling power from said host, not providing it.
one suggestion is to just clip the red wire inside your micro usb cable/adapter.
btw the adapters i use do fit snugly side by side, without modification.
I've been following this thread for a little while now, and I wanted to share something I found.
I was looking at the Motorola Travel Webtop adapter. And I was curious to see whether it could be tweaked to suite our needs. I naively thought/hoped that I could flip the connectors in the device to make a small adapter to connect the Atrix to newer Lapdocks. Unfortunately as you can see in the pictures below (sorry not enough posts to link to the pictures) the two connectors are connected via a PCB not wires or a ribbon cable. Although I still have high hopes that I can de-solder the HDMI and USB connectors, and use a small length of flat ribbon cable to connect them and then re-positions the connectors in the case, to build a micro adapter to use the Atrix on the newer Lapdocks. Should this fail this will at least prevent others from making the same mistake, and solve the mystery of what's really inside the Webtop Travel adapter.
Do any one know if this Micro HDMI Cable would work for Lapdock.

This was my experience as well. Try other cables before you swap out your phone! :good:
The same with my cable. I guess they did it on purpose, that whenever your phone is 'tugged' the usb cable will be released instead of your movement being violently restricted by the force of the cable, which may cause you to drop your phone.
Any way, i bought a 3rd party flat USB cable which length exceeds 3 - 4 times the original cable , and it fits tightly in my phone's USB port. So i believe it is cable related.
I have the same problem, I guess it's just the one they sent. Oh well.
I did buy another cable, however I noticed that charging becomes extremely slow with it. I'm hoping to be able to find a better one that can support the higher charge needed for the phone, in the meantime I'll be leaving the phone down while charging I guess.

+1 same thing for me too. I was so worried thought it was a problem with the charging port but it seems the problem is with the charger cable. Using other cable is no issues.
Obviously it pops out very easy. I'm on my 3rd Samsung Micro USB cable, all are same.
But then I've tried my friends Galaxy Ace cable and it was fine. So you just buy a different Micro USB cable which will have same 2A output like stock one.

I. too, was worried when i first got the fone.... but it's the stock cable... tried another cable from another brand/manufacturer and it fits perfect.
I seem to be quite lucky. My stock cable fits nice and snug. I can even dangle the phone upside down holding only the cable and it wont come out unless I swing it or tug it harder lol
If you compare the stock cable with other cables you'll see that the plug on the stock cable is usually shorter than other cables by a millimetre or 2 so the little prongs on the plug probably arent grabbing onto the slots of the phone

Difference between normal and OTG USB cable is that OTG has pins 4 (sense) and 5 (ground) shorted and on regular cable pin 4 is not in use. If you put a switch between these two pins you can switch between regular USB cable for charging and OTG for connected devices.
Some apps can be found on Google Play Store that claim to be able to switch between or enable simultaneous OTG and charging, but most are for specific devices or group of devices, none for G Pad 8.3. Most promising is maybe Faux123 Kernel Enhancement Pro (3.77€ and requires Root+Busybox+SuperSU).
Too bad our tablet has no secondary charging port (like Sony has magnetic charging port for example), but least intrusive would be to use powered USB HUB, let it power the connected devices so the battery drain on the tablet will stay low.

Thanks for that - Very good info! Allow me to pick your brain a little more: Looking at the cable i have (in the OP), do you think that by just connecting an external power (red and black) to the cable just before going into the tab would work somehow to give it power.
It's intreging what you said about being able to switch from regular USB (that can supply power) to OTG just by jumping those wires. I'm trying to picture something in my mind to accomplish what we want but the "light bulb" haven't came on yet - any suggestions?
I want to use the tab in the car PERMANENTLY so i need a way to charge it while behind the dash. I would want to use a mouse as well so OTG is a must.
In any case, i'm going outside right know to split open that cable and see how it's connected inside, maybe then the light bulb will come on in my head.

Try it out, you got the cables!
When pins 4 & 5 get shorted the tablet may be configured only to output power, not receive it. I have only OTG adapter cable and the supplied USB charging/data cable, so I cannot test this stuff.

I would buy micro USB male plug, some heat-shrink tubing with glue, switch (3A) and split OTG adapter or HUB. Cut off the male plug fom the adapter, solder on the new plug to the adapter cable as normal USB, solder on the switch to pins 4 & 5 of the plug, check it for continuity and shorts, test it on the tablet, if good - secure the new plug to the cable with heat-shrink tubing.
EDIT: Possible solution with resistor described here
Our device, if it can be tricked this way, may require different resistor from the one used in the tutorial (usually in 36KΩ-200KΩ range).
Ok, I'm chopping it up! I spliced-in the red and black wires from a USB cable into the OTG cable (in the OP) and sure enough the tab gets power. However, it no longer detect the mouse or any thing else (kind of expected). Tomorrow i will try bridging pin 4 and 5 and see what happens. If that don't work, i will try the resistor. :fingers-crossed:
I have read that devices on OTG get polled regularly, but charging is not, i.e. if you start charging and after that short the pins 4 & 5, it will continue charging and you can use your OTG devices. Hope this holds true to the G Pad as well.
Isn't micro USB a "standard"....??
Then GEEZZ why do one manufacturer thinks it's ok to eliminate a pin completely! i assume that when i pay for that cable, i will get ALL 5 PINS even if one is not connected - rip-off! :laugh: This manufacturer not only didn't connect pin 4, it was eliminated completely; stopped me in my tracks! Fortunately, i have an extension that have of all things ALL 5 WIRES CONNECTED! Imagine that! But now, i don't have any time to chop-it-up until tomorrow. With the 5 wire cable, i will short the yellow and black wires but I'll check here first to see if I'm warned against it.

Hi manny your car kooks awesome. I have one question. How you connect your speakers from the car with the G Pad. iam also interested to built a GPad in the car !

Yep weneed more info on this as i would like to fit my pad in the van,, how did you get fm radio on there.
Nothing good to report. Connecting the power wire to the OTG cable and shorting the 4&5 pins does nothing different. I can have it charging and when i disconnect power, it then detects the mouse (that's a good thing) but when i plug the power back in, nothing happens! Ideally it would disconnect the mouse and start charging again but no-go. Having the 4&5 pins shorted or not makes no difference.
Still have a couple things i will try before i give up, one is the resistor and the other is a more simple OTG cable.
Will report back.

I understand that you would want the cables all hidden behind the dash in a car and can't be connecting and disconnecting plugs all the time, at the most just flip of a switch should make things work. The resistor trick would be ideal, if it works.
What's the exact sequence you did things in?
- Mouse and charger connected to the tablet simultaneously with pins 4 & 5 not shorted, tablet charging - short pins 4 & 5 - what happens?
- Only charger connected, pins not shorted, short pins and then connect mouse...
- Mouse and charger connected to the tablet simultaneously with pins shorted, mouse working - unshort pins...
- Only mouse connected, pins shorted, unshort pins and then connect charger...

I would have to record in what sequence i do things to remember but it seem i have done every combination possible. I do remember doing these sequences after a fresh reboot of the tablet and BTW i made a simple cable out of a know working (single) OTG cable and splicing-in the red and black from the cable that has 5 wires connected, leaving the pin 4 wire disconnected and extending a pigtail from the black wire so i could short the yellow and black to hopefully force OTG:
- Power plugged in and mouse plugged-in then plug the cable into the tablet - it detects the mouse but does not charge.
- in the above state, shorted the yellow and black wire - no change.
- separated 4/5 then disconnected the mouse leaving power connected (expecting that the tab will then switch to charge but) - nothing. The mouse did disapear but the tab did not start to charge.
- shorted 4/5 (for ****s and grins) and as expected - nothing.
Again with a fresh tablet:
- with (ONLY) power connected to the cable, inserted the cable into the tablet - it started charging.
- in that same state, connected mouse - mouse was NOT detected but the tab continued to charge.
- with mouse plugged in, shorted 4/5 - no change (charging but no mouse detected)
THIS IS THE IDEAL SITUATION BUT JUST HALF WAY:
Rebooting the tablet with both power and mouse connected and cable inserted, the tab starts by accepting the charge (no mouse) but get this, plugging-out power makes the tab switch to the mouse right away! That would be good except that plugging the power back in does NOT make the tablet switch back to power, in fact, nothing happens, the mouse just continues to be detected.
If i had 2 cables, one only for power and the other only for OTG, i could pull one out and replace it with the other and both functions would work; i don't understand why that same "switching" can be recreated within one cable??
This is beyond me, the last thing i will try is following your sequences to the letter and with the resistor, if that doesn't work - i give up! :crying:
