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 ;-)

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
Hello,
Can you have USB OTG and phone charging at the same time? Or even better: HDMI + USB OTG + charging? Without power the phone discharges fast, not to mention - with HDMI out connected I won't be able to connect external HD with movies... Oh, bother...
Or is there some magic do-it-all dongle?
I need it too .
I hate some cable in my bag. One Cable for all is great
USB OTG does not support charging as it has to supply current to the external device.
MHL (HDMI output) does.
Dude, I really hope I'm not misunderstanding, but what is the problem to which 'USB OTG and charging at the same time' is the solution?
Surely you pop your USB stick in, transfer the file and then... stick the charger/HDMI cable back in... and stream wirelessly/over your network?
What were you hoping to achieve? There are several options...
Just taking a guess... maybe he wants to use keyboard and mouse etc with his phone, desktop style

I wanted to do the same thing but it isn't possible . I do however stream from my nas if I don't want to copy stuff to the phone.
Technically, the USB-OTG standard includes provisions for handling this.
There are several occasions where you would want to plug an accessory into a USB-OTG port and still be able to hold the state-of-charge in the host device.
The specific document: Battery Charging Specification, rev 1.2
ACA subsection (Accessory Charger Adapter)
The ID_OTG pin acts as an input in this mode of operating, indicating whether or not the host is allowed to charge.
Figure 6-6 shows the typical architecture.
Sounds promising. I will look into that! Thanx.
Any news on this?? :fingers-crossed:
so can we use otg and mhl at the same time without charging
Yes, this is pretty much possible. I have implemented the aforementioned OTG ACA support and got it to CyanogenMod9 upstream. Anything which uses the same kernel (or, if you can cherry-pick changes and compile your own kernels), could use that too. Changeset URL: _ttp://review.cyanogenmod.com/#/c/15850/
You need to use a regular USB OTG cable, but place a 36 KOhm resistor between ID pin and GND, then you should connect GND and Vdd to some power source. I used an MHL adapter which I had no use for, as it had two of three connectors I needed. This setup allows me to watch movies from 2.5" notebook hard drive while simultaneously charging my phone if I plug in a 2A-rated adapter. Note that it's impossible to use 650mA charging rate due to chip restrictions (USB HC is too stupid to understand the direction of current flow, and it reports an over-current condition); you have to settle on 450mA.
If you don't know how to solder, or if you use something else than CyanogenMod9 and cannot compile your own kernels, you are out of luck.
I have tried to find an existing USB OTG ACA dongle, but I was not able to find any. If you will be more lucky than me, you can just use it--my patch is compliant with USB specification and will support any compatible dongle.
It's possible.
You need cable y usb. I did it myself.

Duh, I read right past this post... 36KOhm on ID <<< got it, now to experiment!
wow!
it would be amazing if such a device existed!
Hello,
I'm new to this forum as i didn't need it yet but now I have a question.
I know this thread is kind of old and I'm not sure if there are still (m)any people using a GT-I9100... though it would be interesting if anyone found a solution on this topic.
I read several threads where people were discussion if charging and OTG is possible at the same time but no one could verify a specific resistor. Actually i tried a resistor valued 124k between GND and ID but it didn't work. I also read about 36k and other values but nothing verified. Could take a while to try several resistors but i really no one knows a solution i'd try this
So just so sum up, i don't need "MHL and charging" or "audio out and charging". The mode i'm looking for is "OTG and charging".
My Goal: a Docking Station with mouse, keyboard, flash drive(s) and charging to remote control my computer with a software like splashtop.
Hopefully anyone has useful information on this, thanks a lot for any kind of support

Thanks for your answer!
Today i made my 36k cable, this weekend i should have some time for the kernel patch - hopefully
I still have some questions about the kernel as i didn't use any custom ROMs etc on my phone. All I have is a "standard" root kernel without any further changes but root. Need some hours to read into this. What i didn't understand: Do I have to use a specific CM9 or can i use any CM9 (or maybe CM10 or any other CM past 9)?
I wasn't able to get the link working "_ttp://review.cyanogenmod.com/#/c/15850/" when replacing "_" with "h". What can I find on that page?
Hello friends, I am new to this forum, but certainly not new to the tablet world. I purchased the iconia a100 a few weeks ago and I must say it is a superb tablet in almost everyway. That being said, I am trying to come up with a solution for the lacking usb host on this tablet. I am certainly not a dev, but I am wondering if there is anything in the works for a working usb host? Does anyone know if acer has any plans to offer an adapter or even a different docking station with the usb host working from the 40 pin? If anyone has any ideas or would like to start a project i will be glad to help in anyway I can. While i was researching this usb host problem i see that there was a very sinilar situation with the galaxy which has since been resolved. Any suggestions? Thanks
Not yet possible, but you can pretty much count on it to be baked into a custom ROM when we get the ability to fully unlock and root this device. Root is already possible, and done. Unfortunately, we cant really do much development on it right now due to the encrypted bootloader. Most devs are waiting for the ics update in January to get the ball rolling on tweaks and hacks to the a100.
Sit tight, they'll have you up and running in no time
ummmmm............ could you repeat that?
This is also #1 on my wishlist. However, I don't know if that is even possible with a custom ROM; it requires the hardware to support it and I don't recall seeing any teardown that states that it would be possible.
I've seen it done in various phones, but don't know if its been posted on any here, but I'm sure a search on the forum would help find them. Its a matter of reconfiguring the port in the programming and getting an adapter from micro USB to standard USB.
But don't quote me on any of this, I could be mistaken with other devices. There has been talk about USB hosting on the a100 before.
ummmmm............ could you repeat that?
Yes, you would need something called an OTG (on the go) adapter. The hardware in the device has to support host, so it is not JUST software.
I can confirm that i have tried the otg adapter as well as other adapters...and it only works as slave. I would just like someone to confirm that usb host is possible [that the harware supports host capabilities]. I am just glad to see there are more people interested in fixing this problem as this tablet is superfast and top quality in every other way in my opinion. Thanks again
Maybe something comes out of
http://www.circuitsathome.com/mcu/programming/android_adk_compatible_usb_host_library_release
I ordered an OTG cable and once it comes I will take a look at enabling USB host mode.
I am guessing that the hardware supports USB host, but will need a kernel module and some scripts to enable it.
I also suspect that the USB port will not supply power to an attached device. If this is the case, the workaround is to attach a powered USB hub to the OTG cable.
Crossing my fingers, and waiting for that OTG cable to come in the mail...

USB host is enabled in the kernel. Hardware does support USB host.
Acer left it off the board entirely, so I doubt much can be done without hardware modding, which I'm all for lol.
Tapatalked from my Galaxy S II.
Sounds grim if the hardware connection is not there, are we sure that the port is just not supplying power?
do the kernel modules load? (e.g. usb-hid, usb-storage)
Has anyone actually tried to:
a) insmod the correct modules
b) force change to host mode (the device probably has to be either slave or host, not both at once)
c) connect something (e.g. a mouse or a thumbdrive) through the otg cable and a powered usb hub?
At least I won't have to build a kernel to test this out.

I know this comes up every now and then, I really dont know how far anyone gets before giving up. Feel free to try out whatever you want, while I don't care about USB host I know a lot of people do and would love an update on any progress anyone can make. Even if its just things that don't work.
Acer is generally lazy and cheap, we use the same kernel source as the a500 which has host, which is why we also have it. It could be modules, though I doubt its so simple. Also a powered hub would be needed, there is no power supplied to the port that anyone has found. This could be remedied with some hardware work I'm sure. The hub would also need to be one way, meaning not dumping power to host as I doubt the a100 will take it and without protection would likely suffer damage if the power pins are even hooked up.
The system itself runs at 12v though I'm sure there's a 5v rail someplace but if it can support powering anything past maybe a flash drive is unknown.
Take a visit to iconia-dev on free node, they'll know more of this then probably anyone here does lol
Tapatalked from my Galaxy S II.
The A500 does not implement USB otg, but rather a standard USB port. In other words, USB otg is not necessary for the A500 since it has a standard port. The USB otg standard allows a the port to act as both master and slave depending on the connection. In the A100 service manual, the schematic shows only one connection to the chipset (client), host is unconnected, which could be a problem. However, it is known that the Tegra 2 can support otg connections. I'm not certain, but it may be possible that by shorting pins 4 and 5 in the micro usb connector (ie, using an otg cable) and with the proper kernel level support, the A100 could still act as a USB host, albeit with no power supply to the micro USB port.
I'll continue to investigate this once I have a chance to build otg support into the kernel and recieve the otg cable.

Thanks for that, but one thing, its already in the kernel. However Linux society and/or waydownsouth would know more about what's in there, I just know it isn't blocked there. Modules etc I don't know. I look forward to seeing some progress on this topic.
Tapatalked from my Galaxy S II.
Pulled the kernel config from my tablet, you are correct, otg support is built into the kernel.
I'm using ezterry's kernel, almost everything is built in, there are only a few modules that have nothing to do with this.
I tested with an OTG cable, which shorts pins 4 and 5 in the micro usb connector. As expected, this did not enable USB host mode.
I tested wtih 5V going into the micro usb connection, as some of the non-powered devices need that voltage applied to activate the port, still nothing. (and no damage!)
I added a few other things to the kernel, the dmesg output changed slightly compared ezterry kernel
When connecting otg cable with 5V, dmesg shows:
tegra-otg tegra-otg: SUSPEND --> PERHIPHERAL

In the possibility that USB host is not possible on the micro usb port, a hardware mod could be done. There are points for a mini PCI-E connector on the motherboard (this is where the 3G module would be for A101). Solder wires to pins 36 and 38 for USB data, 4 for ground and connect them to a usb port. The PCI-E only gives 3.3V, but power could be supplied by a powered hub instead. There is even space inside the unit to mount a micro usb connector on the end with the power button.
The main roadblock is that the solder points are on the back side of the pcboard so you have to fully disassemble the unit to remove the motherboard. It would actually be fairly easy to do if the points were showing when you remove the back cover.
I don't think I have the nerve to actually try this.

Well if you want to play it like that, you can use a mini pci-e > usb adapter, which is also available with and without sata too lol. It would, maybe, depending on the board used, even line up with the sim slot, so minimal case cutting would be needed to make it accessible for usb. Straight drop in for an A101, though we lack the actual slot for it. Might be something I'll try later on.
Edit: I forget, does the sim slot line up with the pci-e slot? Been awhile since I saw the inside of one, so I may be wrong on that point.
There isn't an actual mini pci-e connector in my tab, it's just the solder points, so you would have to solder on a connector to use the adapter. The sim slot doesn't line up. But it looks like the empty sim slot is not high enough for a micro usb port to fit anyway.
I tried the hardware mod. Unfortunately the mini pci-e is not hooked up to the system. In other news, the motherboard is very easy to remove and reinstall.
there is a ROM in which they have implemented the usb otg?

I just recently got a Samsung Galaxy Note 10.1 and so far I'm quite happy with it --- except one thing, I cant find a cable that lets me charge the tablet *and* use the USB Host (OTG) port... (i.e. read files off a USB drive or play a game with a USB game pad while keeping the tablet plugged in)
Is there a way to do this? it would seem to me that all it needs is a splice to give power to the Power +/- pins on the connector while keeping the OTG Data +/- pins active...? (I know nothing about the pinout so I could be wrong on this)
Just to be clear I want to use the OTG adapter WHILE CHARGING (I've found one device that gives both these options but says "only one function may be used at a time")
Ideas?
Discussed dozen times in 10.1 forum. Actually it is not possible. Build an otg + power cable myself but it only works with timing and with a specific procedure... quite annoying. Wait for a custom rom somewhere in the future as I do.
You may have issues trying this, OTG cables are iffy under Jelly Bean. Some may work, some may not. In fact, Google removed references to OTG support for Nexus devices last November since OTG is so spotty. Splicing a cable that might work may kill it. Decent battery-powered USB and SD hubs are available and bypass the OTG problems. I have the RavPower RP WD01 and love it. The USB port will support drives upto 3T. It also has an SD card slot.

Powering the USB devices isn't a problem, I have a nice hub that powers them without issue, even extremely power-hungry devices. I was wanting to charge the tablet's battery while using the OTG adapter (original thought was for USB-gamepad-ing since high-requirement games drain battery, but I've since started using a PS3 controller over bluetooth so I can use the OEM charge cable and wireless for gaming --- but USB drives I'd have to copy the files over to internal flash or a MicroSD card to view while charging and i've found that the cards dont like files that are 8gb in size... (FAT-32 restriction iirc))

I saw that when I google'd but thought maybe there had been some new developments (especially with how this site's members love to tinker with electronics and write custom firmware). It's not a huge issue, since the Note 10.1 has amazing battery life (it's actually matching or doing BETTER than my iPad in most circumstances) I just like to never run the battery down low.. (why cant tablets have user-replaceable/swapable batters like most phones?!)
Thanks for the info!

which only costs $1.49 with free shipping. It was $0.83 when I purchased it last year.
It works on the Nexus 7 LTE 2013 with USB thumb drives, but does NOT provide additional power for devices which may need it.
Can you confirm thath this otg power cable charges the nexus 7 2013 while still reading peripheral data from usb port?

I find my Chromecast must have this cable powered in order to use a USB thumb drive to root and replace the android operating system.
You can save a few bucks for a cable that does not provide power if you want.
I also own this one:

(purchased from amazon seller: Digital Center(Ships From Hong Kong)
which only costs $1.49 with free shipping. It was $0.83 when I purchased it last year.
It works on the Nexus 7 LTE 2013 with USB thumb drives, but does NOT provide additional power for devices which may need it.

I can only confirm that both OTG cables I own work on the Nexus 7 2013.
i am using one that came with my minix x5 and it works on all my android devices, but the connection is loose. i would be surprised if there was one that did not work as the cable itself is such a simple thing.
i would also like to know of a working powered option. i thought the powered cables only supply power to the accessory, not to charge the device itself.

Since you have the USB OTG cable with the additional cable for charging, would you mind testing it by:
1). Connecting a working USB device (mouse, HDD, etc.)
2). Connecting the USB power to the 2nd cable in the OTG cable
I am trying to use a BT keyboard and non-BT wireless mouse and charge the N7, but unfortunately, it drains the battery down heavily.
PS: I CANNOT use both BT keyboard and mouse AND have Wifi ON, as it interferes with the BT radio, making the keyboard and mouse lag heavily. I have created a thread on this also.
What thread is that?

I have connected a USB thumb drive. The thumb drive works with or without power attached, but it will not charge. I suppose it is built to provide the power to the attached USB device and not to the phone / tablet.

I just got a cable from monoprice and it works great.

Has anyone found an OTG cable that can be used to power a thumb drive and apply power to the Nexus 7? I'm trying to find one for when I'm traveling. I'd like to be able to watch movies and keep the device charging.

Perhaps a small powered USB hub will reduce the power drain on the N7?
Have a look at this.

My y-connector from my n4 doesn't charge while using USB otg. The ability to do so is not written in the software. I'll try to locate the source and report. OTOH, the USB otg connectors from my GNex and N4 all work on my N5 and both old and new N7's.
EDIT: I just ran across this. I'm sure it's for the original N7. I wasn't even aware of it so obviously have not tested it. I did use ziddey's kernel on the N4. Still searching.
2nd EDIT: Available for N7 FLO/DEB 4.4.2. I'm running franco but will revert to stock then try this (as soon as I make a nandroid of my device).
3rd EDIT: That kernel does work to charge while on usb otg. It is a setting you choose to activate during the set-up. I just chose stock everything until I got to the power choices. I will say that although the install was successful, I came as close as I've ever come to thinking my device was bricked. After the install, the screen went black and I couldn't do anything. After about a 30 sec power button mash, everything booted back up. This video shows installation on the N5. Some choices are different on the N7 FHD. As I said above, I was NOT returned to TWRP after installation.
There is a note about altering a sys file for OTG peripherals. I only attached a flash drive and the usb_charge_mode was set to Y (I assume for yes). You may have to perform the edit if using a peripheral device.
