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.

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
Anyone can help me??

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...

Stock 10.1 2014 and USB HDD via OTG

FYI guys our stock Note 10.1 2014s have native support for USB HDDs via On the Go (OTG) cables. However, the drive cannot be NTFS: I tried a couple of different OTG cables, a powered USB hub for powering the HDD, etc, on my NTFS (a 2 TByte Passport) without luck.
I then quick-formatted the Passport to FAT and BAM everything worked perfectly: the USB device was recognized and the native "My Files" app auto-opened to display the contents of the HDD (i.e. an app like "Nexus Media Importer", which I used on my N10, is unnecessary)
Very impressive. I am diggin this tablet more and more...

Hi
The problem is the Kernel of the P605. On my Galaxy S4 i´ve solved the problem with the installation of a "hacker kernel v7 leak". Now it can read an write NTFS devices.
But for the Note i cant find a other kernel yet :crying:

Rooted users should try OTG Helper ... that seems to do the trick for NTFS.

If this is the case I think I will order a OTG cable right now
@Zumajay So basicallyallI have to do is turn my WD Passport into FAT and it will work via OTG?

yes, any massive storage with fat32 format, can be read with this tablet, just remember that fat32 has a file size limit of 4gb

you need the ntfs file system drivers inside the kernel in order to read nfts hdd format

I originally tried all of the NTFS mounting apps and none of them worked. Just formatted my HDD's to exFat then there is no 4gb file limit and all works fine.

Also having root does not help.
The problem is SELinux in Enforcing mode, it blocks all the programs that try to modify System partition by installing, in this case, the NTFS drivers.
Until someone will make a P605 kernel with SELinux in permissive mode, there is no way to manage an NTFS partitioned usb drive.

No more news about samsung note 10 ed. 2014 and solution for ntfs?
inviato dal mio Lg g4 h815 in attesa di qualcosa di nuovo...

Didn't think the P600 can run an external hard drive.
Tried just now with stock rom and Xluco kernel, that one's modded to support NTFS filesystem, but I haven't managed to get any externals to respond to the device.
-plugged in a small pendrive to test, and it reads the device.
-plugged in an external drive and nothing happens
-then installed the USB OTG Helper app, doesn't do anything either, says it didn't found any external to mount.
-rebooted the Note with the hard drive plugged in, nothing happened too.
-possible power supply problem, where the device didn't have enough energy to power an external device?
The guys above probably have the P605 model, the Snapdragon one, and formatted their drive to something other than NTFS, something that I can't afford to do lol. Yeah, the processor can be relevant too, because the Snapdragon Note 4 can detect and use a 512gb SD card (not microSD), whereas the Exynos version is limited to 64gb only, if I remember correctly.

[Q] Cannot mount SD Card via USB OTG and stickmount (root) - works on Galaxy S2

Hi,
I recently bought a USB OTG cable and an "Integral USB 2.0 Single Slot SD Reader " so that I could use my Nexus 7 to view photos from my camera.
At first I tried using Nexus Media Importer to view files on the device, but this did not work. I have successfully been able to use this application to mount a USB thumb drive via the USB OTG cable.
I then rooted the device and installed stickmount. This did not seem to work either and there were no signs that the device was recognised by the tablet (the red light did not come on). I configured stickmount in SuperSU so that it has root access. I did not copy any data or apps back onto the device after unlocking it, and I am using the stock android 4.4.2 ROM.
I tried mounting the SD card using the card reader and USB OTG cable with my Galaxy S2 running Cyanogenmod. This mounted as soon as I plugged it in so I doubt there is a problem with any of the components.
I have tried mounting the drive both with USB debugging enabled and disabled. Is there anything else that I can try?
Thanks,
Ciaran

Reboot your device while keeping the OTG cable connected.

Thanks, this does allow the drive to mount successfully; however, if I remove the drive then re-insert it it does not remount, nor does it show up in Stickmount. Is there a way to remount the drive on-demand - just like my Galaxy S2?

You can press the 'thanks' button if it helped. Till now, I have not come across any such method to mount the OTG cable on demand. It's a cheap ploy by Google and Asus that they do not allow native OTG support on the Nexus 7 2013. Just to promote the cloud services. Mounting OTG cable is so easy on the Moto G and Samsung devices. It's a given these days.

It's gotta be the connections your using. Either the Integral SD Card Reader, or the OTG cable you are using. I never have any issues using stickmount with my Meenova MicroSD card reader. Have you tried other adapters?

^This, stickmount mounts my meenova as well as my OTG+USB thumbdrives on demand, no issues whatsoever, no need to reboot or anything, it just automounts and it's ready to go.

external hard drive support

Iam considering buying an external 1 terabyte or more hard drive to keep my files so I can use my tab without a laptop
But I don't know if it will support that kind of storage via usb otg
Pls help if anyone tried
One other question is this will drain tab battery or what

I can use my WD USB HDD mounted via OTG and formatted NTFS using paragon app to mount (root required). This is tested with my SkyHigh kernel.
I don't know if device natively supports it with stock kernel, but should be able to mount at least fat formatted USB HDD without root and visible with Samsung file manager.
Not real sure about the battery, but would obviously use qite a bit. I haven't tested to quantify the "bit".

I have a pair of 2 TB Seagate Backup Plus drives that I use with my tablet. I formatted them as exFAT on a Windows computer and they automount on the tablet when connected. The tablet does not provide enough power to spin the drive. I use a USB Y cable to supply extra power from another power supply.

Could ANYONE please confirm that ?
If it's true it means that a fix is possible via system files.
