Hi All,
I have rooted my SGH-T989 and have flashed Zedomax's kernel to allow the USB Hosting functionality on my phone. This has worked great and I can now use a mouse and keyboard via a USB Splitter into a single OTG cable plugged into my phone.
The Setup:
Samsung Galaxy S2 SGH-T989 (Rooted)

Normal USB mouse and keyboard
KVM Used to switch mouse and keyboard from Desktop to USB Hub for SGH-T989
The Problem:
If I use the mini to USB cable supplied with the Belkin USB Hub to the OTG cable the mouse and keyboard are recognized and usable. However, if I don't use the OTG cable it will NOT recognize the mouse and keyboard.
That is not my issue, I'm ok using the OTG cable, but it leaves me with a Female USB placeholder. Therefore, I have to connect it to the USB Hub. Obviously, the Mini to USB A cable worked for hosting, but it does not supply power to the phone even though the USB Hub is plugged in and powered.
My initial thoughts were that the USB Hub does not supply power out the side mini USB so I bought a 1.0 USB A to A , 2.0 USB A to A, 3.0 USB A to A, Gender Changer for OTG cable. and no matter what cable I plug into the front USB slots on my USB Splitter, I get NO POWER and NO HOSTING. Nothing seems to flow through to the phone other then the one Mini to USB with OTG, but leaves me powerless.
I have also bought the docking station, which I later found out that even with the OTG cable will not push the hosting through to the phone and had to return it in favor of a more generic stand to hold my phone landscape.
I am out of ideas as to what to try next to get power and hostability to my phone. Please help!
Thanks,
Sam
Odds the USB hub powered? I remember that the first OTG kernel that came out said the hub had to be powered to use a mouse or keyboard.
The hdmi cable has to be plugged to the phone charger as wellfor it to work

Yes it is powered, I have also tried unplugging it to remove power. However, the OTG cable will accept the KVM mouse and keyboard plugged directly into the OTG cable itself.
The one thing I'm not certain on is whether or not the mini to USB out of the side of the USB Hub is supplying power or not. However, that is the ONLY spot that is working for pushing the KVM Mouse and Keyboard through to the phone. Without just plugging KVM directly into the OTG cable.
The KVM is plugged into the USB Hub and the Mini is plugged into the side by the power and then plugged into the OTG. This setup works for hosting, but all the variations of plugging into the normal front facing USB spots of the hub have failed to do anything but bring in power. However, I have NEVER successfully brought power through the OTG cable, so I'm not even sure it can support power at this point.

the only devices that does not need additional power are USB keys / flash disk storage and the likes
everything else you need to plug it into a powered USB hub, and have the hub connect to the USB OTG cable
and you do not need any special Kernel for USB OTG to work on this phone
USB OTG works from factory stock ROM (i just tried it to verify )
Hi Allgamer,
Thank you for your insight. However, I did try the OTG cable before getting the special kernel and it DID NOT function. Once I downloaded Kedomax's kernel I was successful. This appears to be a feature they removed from T-Mobiles version.
As for the Power issue. If you guys would be so kind as to reread my initial blog and reply before posting power things to try as I have listed that I have tried powered and unpowered and plugged directly and indirectly and through a usb hub and without, all variations and cables to plug and play have been exhausted.
I'm looking for a more advance analysis that may help provide a solution to my current problem. I'm not sure if the OTG cable can allow power to pass through to the phone or not. I have yet to see that work. I'm also thinking I cannot host without the OTG which seems as though it would leave me in an infinite loop.
Here are more along the line of questions that I'm hoping someone can provide insight to as I have no way of answering these questions myself without an extended work bench and wider test result devices.
1.
Can anyone confirm that the OTG cable can in fact provide power to the phone as well when plugged into a USB Source such as a HUB that is providing power out the USB ports to the OTG cable itself.
2.
Can anyone confirm that the OTG Cable can still support hosting capabilities if power is being sent up the cable or does this disable it in some way.
Thanks again for your responses, no disrespect intended by my redirection of the thought process here.

I bought a original Samsung USB OTG Cable for my Samsung Galaxy S3 from online store ( shopsection.com ) , can anyone post tips and tricks about it.
according to my testing, Most of all USB devices can access
1- Amazing cable, it works perfect in Galaxy S II, Galaxy S III and Galaxy Note
2- Connect pendrive 2GB, 4GB, 8Gb, 16GB and access files , documents, songs, movies instant from your S3
3- Like to draw anything without C-Pen stylus? connect USB mouse and draw anything u want as like in computer mouse cursor
4- feeling touch to type on touch screen? connect USB keyboard via OTG cable and start typing SMS and Emails.
5- Does your friends running out of battery ?, connect their mobile with their usb data cable to OTG cable and get charged
6- Also if your friend give access for "Mass storage" access his files from his mobile phone
7- want to take instant printout from your S 3, connect printer USB to OTG cable and give a shot
Article from other websites about OTG cable,
- Remote Access your mobile using Data modem
- support PS3 controller
also if anyone has more tips and tricks for this OTG cable, kindly post it. so thrilled to enjoy its benefits.
I heard also Xbox 360 wired remotes work as well
I have a chinese non-oem OTG cable and works fine with pretty much every USB devide I have (usb memories, keyboard, mouse). I havent tried game remotes or a printer.
Not as amazing as the adapter Samsung will be releasing whenever they can be bothered because it will use the full 11 pins and allow MHL and other accessories simultaneously, but like always they take so long releasing accessories people just get pissed off while they waiting.
Yes Micheal 100% acceptable. only advantage for OTG cable was they launched long back after few months from Galaxy SII. But same cable we are using it for Galaxy Note and Galaxy SIII. But we are really worried for Flip Cover launch for SIII. it took nearly 2 weeks time from SIII mobile launch.
There are plenty of local manufacturers releasing case and covers and even OTG cable. only this guy has the original samsung OTG cable in India shopsection.com/item/USB_Host_OTG_Cable_for_Samsung_Galaxy_S_3 for sale with offer price.

You need MHL cable to connect HDMI to Tv and you can't connect over Mass Storage mode to Tv, Car etc because Samsung in their wisdom decided not to include it, and I know iPhone has things like blood pressure and heart rate monitors you can connect but never heard of it on Android, but it's possible to create a driver to connect pretty much anything with a USB port to Android.
Bought this otg cable for cheaper rate in local market, it worked for 2 months but i could not connect my Sony Pendrive 8GB. any application needed to upgrade on my Note to support 8gb? can your post me the link whr u purchased samsung otg cable, how long u hv been using it? is that original with warranty?
all those tips tested by you?

I myself tested most of features and its working as i said. Not sure what is problem with your flashdrive, but mine everything works. format your memory card and test it again.
bought it from https://www.shopsection.com/item/USB_Host_OTG_Cable_for_Samsung_Galaxy_S_3
Its original samsung accessories and you get 6 months warranty. so you can claim if any issues after 2 months. I believe only these guys selling Samsung S3 original products like flip cover and stylus pen in India

Does anybody know if arduino is doing anything with this? It would be awesome if you could edit and upload arduino sketches using an android phone and an otg cable.

The first thing that you need to check is how your thumb drive is formatted. I haven't tried a thumb drive on my SIII yet but on Atrixs I've evaluated they could only interface with FAT thumb drives. NTFS wouldn't work. You should also try a different model of thumb drive, I don't know about the power requirements but it might just be too high.
USB On The Go cable awareness not upto the level. Samsung must advertise about their accessories too as like Nokia. OTG cable is really useful to access files instant. but i wonder why its only suitable for very few models and since Galaxy Y is also has update android firmware.
anybody tried OTG cable other than S III?
Anyone know if a 32GB flash drive would work with otg cable?

I think the external hard drives will only work if you use a usb port multiplier with a external power source. Dont quote me on that though!

I have actually try plugin my external hard drive with 2 headed USB cable, one connects to the USB OTG cable, one end connects to a USB port for power, and it still doesn't work.
It would be nice if it would work though.
Hey guys..is there a way or a cable and an application that you connect your note 2 with a "x" cable to have acces to your external hard disk? Or even flash memory?
I mean note 2 -cable- external hard disk?
Direcrly without using a pc or else.
Like an usb host controller.?
Thx in advanve
OTG cable
you can connect Note 2 and drive, no application needed
( i think will support upto 64GB size)
i use the OTG n it is ok when connecting a flash drive with 32 GB...but couldn't recognize a 120 GB hard disk...is there any other way rather than OTG to connect a hard drive ???
thank you

The Note II can't output enough power for larger hard drives, so if yours has an external power supply then use it or if it's only powered through USB try using a powered USB Hub. Capacity itself shouldn't be a problem.
It does work!!!

I beg to differ your opinion sir,
I have a Note 2 GT-N7100 i purchased the cable mentioned here, got it very cheap at only 2 $ from a local store.
Anyway I tried and connected everything i could imagine that has a usb plug into my Note 2 and they all worked
The devices I tried are : A mouse, A keyboard, A USB flash-memory and last but not least, my 500 GB external HD and they all worked like a charm!!
The Note 2 is an amazing device!!
attached are the proof of some of the devices mentioned above
NB: the mouse picture is taken from the Galaxy S2 , but it is almost the same for the Note 2

Would you kindly provide the mount path?
so basically what I have is USB OTG cable not the Y one . and a hub . what I wanna ask if what if I plug my charger into the usb hub will the phone charge? and if I plug a flash disk will it mount and charge the phone without breaking it? . if im too confusing I meant to use a M to M usb port from charger then to the hub to power it.
Try it.

No.
It will only charge if the OTG cable has a 124K resistor from pin 4 to pin 5.
Your OTG cable has a short between ping 4 and pin 5, and as such the tablet will drive VCC out.
you would be plugging it into a host port on the hub anyway, which is not powered.
you will need a Y cable, and the SW on the N7 doesn't currently do both charging and OTG simultaneously, this is something I (and hopefully others) are trying to sort out.
Hi ..
THANKS TO ALL XDA DEVELOPERS !! AND OMEGA ROM !!
This is my 1st post so be nice on comments and warnings
I tried to connect external hard disk to Samsung galaxy note 2 . But after a lot of search I can only get more problems to my search but not any detailed description.
So after a lot of research and study in xda forms and web I found solution
Let's b short and simple
Mentioning this is little imp
!!!…… "I'm jus a human not creator so I don't take any responsibility for damage caused to ur world"………!!!:::
Imp things needed
[*]galaxy note 2 N7100
[*]Must be rooted
[*]External hard disk GB or TB (optional)
usb female 2 female pin
otg cable
any rom or kernal with INT D support
(Ycable )or (usb power box) or (samsung docking)
samsung mobile charger or any usb supported charger with 5.0 v or 2.0 A output
Apps needed or used
Busy box
Paragon Ntfs or Hfs
usb otg helper
root explorer
Most of all little daring :laugh:
Steps to followed
check u r note 2 is having int.d support or not then proceed
Install apps from GAP store or Apk files
install busy box
install ntfs or otg any ONE of these
{Procedure}
Now tricky part : connect ur hard disk with y cable using( female to female pin )main data transfer cable one end and the other end to note 2 using otg this should be the straight ends now ther wiil b anther male USB connector free end which has to be connectd to samsung usb charger for power supply to hard disk
[Or]
Using micro-B USB cable instead of y cable lot easier (or ) USB power hub much more easier (or) Samsung docking simple and easy to acess
Check whether u r hard disk is getting enough power (if WD the power light will b constant without any bilkng or fluctuation) or simply check the disks inside is running or not if it makes any ticking sound then it is not getting enough power
If it is getting enough power then proceed and open the app NTFS (I USe THIS )
##If using NTFS jus follow screen shots attached
if auto file explore SD cad /NTFS /HD MOUNTEDhere.. if manual u can choose where u can mount ur drive
##If using otg simply connect and use root explorer /system/storage / here u will find mounted device
All this y cable female to female pin otg will cost around 200 rs INR
USB 3.0 power hub may cost 400 INR
Samsung docking too pricy but does the same thing price starting 2000 to 3000 more or less .Its ur pickcbut work done is same
Important precaution s to be followed
Check
rooted or not
int d support
Highly recommended don't start if u don't know what ur doing is worth doing
Important points to be noted :-
"HARD DISK SHOULD NOT CONTAIN ANY PASSWORDS FOR ACCESSING WHILE CONNECTING ""..SIMILAR TO THAT OF "VCD SOFTWARE ON WD HARD DISK" cuzz there is no software for granting access for this type in android
NTFS FORMAT IS RECOGNISED BY ANDRIODS THANKS TO "PARAGON NTFS AND OTG APPS"
[reference for frends who have lot of questions in mind ]
Before asking
'Int.d' please refer xda forms
about usb 3.0 and 2.0 both can b connected
by connecting Y cable to charger the mobile cant b charged while using hardisk .Mayb in Samsung docking it could b charged I don't no to b precise
B most of all to tch specialists and other .the USB is used for only data transfer and power transfer mostly +d-d ie., 5v so mostly no harm by connecting cable to samsung mobile usb charger
""Your mobile juice or charging may decrease more fastly than usual usage don't panic that is not going 2 b permanent once u disconnect ur hard disk it will be back 2 normal ""
So Paragon NTFS and OTG apps are working with Note2. Great.
