USB on the go Problem

Bought an USB OTG cable few weeks ago and it just arrived today.
When connected to the GS3 I have (T999V), it says "security policy use of external SD card".
When I go into MYfile app and search for USB OTG, nothing appeared (a flash drive is attached with text documents and other various files)
The question, isn't the Galaxy S3 suppose to recognize this USB OTG? and there's no need to install any app to help it recognize it.
Running Team Sonic R3 Custom ROM right now.
Can anyone help me on this problem?
Because the USB OTG is one the the features that intrigued me buying the GS3!

My usb otg cable is on the way from China, so don't have hands on experience. But in ES file manager, if you navigate to /mnt/ folder you can see provision to support upto 6 usb drives as you can see in the screenshot. So try navigating to /mnt and see if you can access your usb drives from there.

Well, it is not completely unusable for me.
After I install the "USB Mass storage watcher" from the play store and mount the OTG it became usuable.
But sometimes it crashes. Also, isn't the device itself already compatible with the OTG itself? Why should I need to install the app in order from me to use the OTG? (these are the two main question here).
Also, the app isn't fully stable, it crashes sometimes and it is very hard to use. (everytime you unplug your USB device you have to mount it again)
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
p.s: I have tried to look in the ES file Manager and I did see 6 USB dirve and 1 usbOTG option. But before I use the app to mount the OTG device on my phone none of the options works. When I mount the device through the program, I can browse the files on my USB drive in the "usbOTG" option.

mouse and micro sd card via card reader is working except my 16gb usb and i tried with every format but still the same result phone restarts !! any reason or seggestion please ??

you said that is working...so i think that can be the 16gb sdcard that can be corrupted or damaged i think so...also try installing original software

I have a strange request, it has happened that after removing a usb drive, the phone no longer recognizes photos and music stored to sdcard?
With es file manager I see the files, but there isn't in galley or music

Follow up on USB Host
I too am using an HTC One X running 4.1.1
I've got an OTG cable and have tried connecting a thumb drive and card reader. Both work. The drives are visible and accessible on the phone. That's USB storage which isn't the same as USB Host, but it shows that the port is active.
I can plug in the dongle for a wifi mouse, it too is recognised and I'm able to use the mouse to navigate around on the phone. This, as far as I understand, is actually USB Host in action.
The problem arises when I try to connect a DSLR and use a camera controller app like Helicon Remote or DSLR Dashboard. The app doesn't recognise that the camera is connected.
What's the difference between the wifi mouse and the camera?
Thoughts appreciated. Thanks.

In fact, there is a problem that any USB storage device on the phone creates the following folder structure:
/ storage / usb / Android / data / com.htc.album / .thumbnails /
Then create multiple copies, can be found in the internal memory, same-path, including folders that contain thumbnails, but empty.
So because of these being used constantly sticks, so when the capture traces of the settings, then any writes to the phone to choose from, but it can not happen, but the capture button will be disabled, but only while again not I step into the menu.
The above mentioned directories erased because the phone reboot always create them again.
If the phone was not rebooted since I've used it and the flash drive has been physically removed it, then if I connect again, it appears no file until you restart the phone.

ya i have the same problem...im using 4.2.2 custom ....and when i use my otg cable n plug my usb it works the 1st time then if i disconnect the connect it back or use another usb it wont work unless i restart my phone....not sure why its not working....but it works for samsung note 3 i tested on my friends phone...

Stickmount not working in v4.3

Anyone else try stickmount to mount their USB device?
I know its not my cable nor the flash drive. They both work in my Original Nexus 7 and I can mount the drive in the TRWP recovery in the Nexus 7 2013.
I also know I am rooted because I have Root Manager installed and it was Granted root permission. Same with ES FIle Explorer 3.

Stick mount works for me on 4.3. I just mounted a flash drive.
It created a usbStorage partition in the root of the internal storage(SD card).
I then used root explorer to navigate to the usb storage folder and voila, my flash drive and all its contents are accessible from my Nexus 7(2013)

Thats good to know then I am wondering why mine is not working? I wonder if maybe I am not rooted correctly. Is there an app that can check that I am rooted correctly?
I actually have tried other mounters as well and none of them are working to so must be something with the root?
EDITED:
I tried a fresh flash drive and it now shows up but my concern is why does that flash work on the original N7 and not on the N7 2013?
Could it be TWRP backups on the drive some device specific protection?

Both flash drives are Def Fat32!!. This is just too weird. The New and Old flash drives work on the original N7, but the old one I used on the Original N7 just will not work on the N7 2013, only the new one. I even did a re-format.
Both Flash drives are Kingston DataTraveler G3 8GB.

Have you tried the one that doesn't work on your old N7 recently, or on a computer to make sure it still works? Probably a stupid question but I figured I'd ask haha

It works on Mac and PC. Just totally lost on this. Maybe the firmware version on this Flash Drive is not compatible with the N7 2013 hardware/kernel.

With nexus media importer there are problems too, I guess they must update the apps to work on 4.3, something has changed.

Mine is not working either on my Nexus 7 2013, but works fine on the original N7. Just shows an empty folder when navigating with ES File Explorer

Maybe ppl can comment on their root methods here to see what works and what doesn't.

I just tried it again to make sure it is still working after I've gotten a few updates, and it works fine for me. Just started playing a video off a NTFS format sdcard with MX Player and it worked fine.
I'm using stock rom and am rooted with TWRP recovery and Super SU.

i just copied a 6gb mkv video onto my thumbdrive and mount with stickmount. it mounted ok but in my file explorer, there is no file despite me navigating to the correct folder.
any help here guys?

How are you formatted? It can't be FAT32 or you couldn't get a 6Gb file on it. I don't think NTFS works without some add-on support.

i'm using NTFS format because FAT32 like you say cant allow me to dump a 6gb inside. What type of addons is required?

same issue
I am having the same issue, rooted with cwm and superSU, lexar 32 gig thumbdrive, 2 .mkv files on it, nothing shows in es file explorer or file manager hd. anyone figure aything out? I messed around for a couple of hours with no luck so far.

I have a rooted device running JSS15R and have a problem with OTG Helper. When I plug in the drive, it opens OTG Helper but I can't mount the drive. It just says no drives found. Tried two different flash drives, both FAT32 and both working on my PC.

fixed my issue

fixed it. Needed the ntfs3g script from http://forum.xda-developers.com/attachment.php?attachmentid=1145436&stc=1&d=1340293802 added to the root of the sdcard for stickmount to read the ntfs files. should have read the whole description on the play store for stickmount.
don't remember having to do that for my 1st gen nexus 7 but, then again, i do drink a lot of beer sometimes...

Did anyone managed to mount USB-OTG in TWRP?

I never managed to, clicking on it does absolutely nothing.
It's quite annoying because i cannot copy stuff to my tab from recovery, i have to use ADB command line instead..
Is it just me?
Edit:
Latest TWRP ofc, 2.6.3.1

Anyone? How do you copy stuff in recovery without ADB?

For accessing files on my USB I use Stickmount and can copy files with my File Manager. I can also flash Roms that are on the USB with TWRP..

But you are talking about app , when you are booted in Android correct?
I'm talking about moving stuff to sdcard in Recovery. e.g. connecting it with my PC in recovery using USB cable wont show me any storage in "my computer", and mounting "USB-OTG" does nothing.
I have no problems copying stuff when i'm booted in Android, storage is properly detected/mounted.
But in recovery i have to use ADB to copy anything to my tab, is there solution for this?

You can't mount to your computer in TWRP. USB-OTG is something different.

Yes I do it all the time. I only have the 8GB so I use USB Flash Drives, or microsd cards through an adapter all the time. I have 3 cheap USB OTG adapters I got from eBay. And one Meenova SDCard adapter. But I use micro SD's with a USB adapter with the USB OTG cables as well.
I pretty much always do this when I backup in TWRP, or am Flashing a rom.
There is two ways to do it really.
One. Go to the advanced and select Mount. On that page I just unselected everything and select USB OTG. Then you don't have to do anything else. Its just like when u select the radiobox it is marked as being mounted, you can then access any files on it using whatever means depending on the circumstances, it will be located at the root of your device, at the bottom there is a dir named 'USB-OTG' select that and your files should be in there.
The second way, go to mount, but below all the options there is a box that says 'Storage 1xxxxx mb'. Etc. Just tap that box and it let's you select either USB-OTG or the devices storage. I use this option to make a band backup so it just defaults to a TWRP/Backups/ dir on the drive. Instead of having to fiddle with all that backing up to get to a custom dir.
It should work. There is no indication that it is mounted if that's what you mean, unless there is an led on your drive of coarse.
Just head to the root dir and USB OTG should be there and you be all good.
But yeah your computer is not a hard drive so you can't just mount it like one. You could technically if you took your hard drive out and connected it with adapters, but a Flash Drive is like $5 these days for one that can hold even the biggest of files you would ever need in recovery.

All you have to do is, Re-Format the MicroSD card in your computer (I use windows 7) using SDFormatter v4.0. Click the "Options" button and for "Format Type", Select "Quick" and for "Format Size Adjustment" Select "On". Thats it! And it will Surely be recognized in TWRP (i use v2.7). Hope that helps.

I have exactly the same problem. I have flashed a number of ROMs from a USB stick via an OTG adapter.
But now the tablet has stopped recognizing the USB OTG. As the tablet (a Nexus 7 Grouper) has no SD slot, there is no way of transferring the ROM files. So I'm stuck.

I never got TWRP to see the OTG if I inserted it whilst the tablet was running. Only when I booted with OTG did it see it.
If you are using an adapter, say USB-A to USB-micro then some don't work well.

I just use a small otg adapter, usb c male on one side and regular usb female on other side.
