USB Host Not Working

Hi guys. So the only thing I've done to my i747 is root it. I've tried both of the USB host apps in the market (USB Host Controller and StickMount) as well as the "SGS3-Easy-UMS" apk that's around, v1.2beta2 and v1.3beta. Can't attach any USB devices. All my flash drives are FAT32 and work well normally. I even ran the USB Host Diagnostics app and it confirmed that Android API, Rooted API, and Kernel "claim support" but no device is detected.
When I connect to sync, I can only do MTP transfers. This is why I looked into that EasyUMS apk because it apparently also allows to mount the phone on the PC as a USB Mass Storage device. During my search I see numerous people connecting flash drives, controllers, keyboards, and even a USB HDD to their sgs3's.
Because that apk requires busybox, and I have busybox, everything looked OK. However, I did once get an error from that APK about possible non-existant Kernel support. USB Host Diags disagree, as do many video tutorials.
Basically I'd like to know whether or not this is supposed to be working, and if not, then how do I go about making it work? I'd like to mount flash drives for easier use with Linux, and would like to mount the phone as UMS for the same reason. I would also like to use a USB Keyboard as well as a USB gamepad. Am I missing something? Are they all using the international?

Are you using a USB OTG cable?

got this one, a couple good reviews confirmed that it works with input devices: Amazon product# B005GI2VMG
i mean it's very possible that the seller just buys from random manufacturers without changing the listing. this one that i have is like the cheapest thing on the market so that may be the problem. i wouldn't mind trying a different one for <$5 w/ US shipping if that exists (recommendations?).

Same cable didn't work for me
I bought the same cable, but from a different seller. Amazon ID number B005N55WHI
And I have the same problem. Tried using it with several input devices and with several different roms and I couldn't make it work. Could it be a power issue? Does the USB device that it is being hooked up to have to be powered? I tried it with mice, keyboards, and flash drives, but all of those devices take their power from the bus, not an external source.

glad you posted. hmm. since we both have the same thing and they're both not working, i'm suspecting it's indeed the cable.
i read on a review of a different cable on Amazon where the guy cut open the connector and found no wire connected to one of the pins. i've had thinner-cable wires before that charged/transferred slower than others or didn't work at all on some higher-end devices, could really just be a cheap-out on the manufacturer's end.
i think i'd like to get a different cable. if anyone can recommend an inexpensive one that's confirmed working i'd appreciate it. so i don't have to shoot in the dark.

I got the one with Amazon ID B00871Q5PI and it worked for me. I tried a Dell USB keyboard, a USB mouse, and a USB DAC and they all worked. All take power from the bus.

got this one.... http://www.amazon.com/dp/B005GI2VMG/ref=pe_175190_21431760_M2T1_ST1_3p_dp_1
would it make a difference if it says its for the galaxy s2 and not the s3? im guessing thats why i cant get it to work.

No, would not make a difference. USB OTG is a standard and for now all devices that have USB OTG work with all USB OTG cables. I've used a cheapass one from Ebay with my S2/Note/S3 for more than a year now.

solved for me
so i got the one drothenberger got (actually that particular link was out of stock for the seller so i got the other suggested one that looks exactly the same, title OTG for SGS3 - item# B00871Q5PI) and i'm in business!!!
someone replied to my negative review of the other one i got in the comments and they said theirs worked. i think they just have different products under the same label or lots of defective ones. i'd recommend to just get the ones that specifically say OTG for SGS3 - the extra dollar or whatever is worth it to save the trouble.
thanks again to everyone for the troubleshooting, hope this topic helps others resolve their issues.

external usb hard drive possible???

My buddy is leaving for military overseas and just got kindle fire...not new one..he also got exteral hard drive. He wanted me to load up the hard drive with a bunch of movies i have for him to watch. Do i have to root the fire for it to read the hard drive? I have no problem rooting since i do it with all my phones and tablets. Ive seen stuff that involves having a OTG cable...im going to assume thats mandatory. What roms support the feature? Can you buy one of those cables at best buy or only online? Thanks for any help

I am not sure if this can be done, from what i have read a few topics on this in numerous places and nobody has had success with an actual external hard drive. Of course for it to even be possible you would need an adapter and there is still no way that i have found to make the Kindle to be able to read the content on the external drive to make it usable on the kindle. If it is i would also like to know how because the 6ish GB that are made available besides the cloud drive are quite small and can run low real fast.

Only one way to find out

I KNOW there is support for usb OTG for the kindle. What ROM to run? I have no idea. I know that you need at least Hashcode's 3.x kernel for it to work. twa_priv has a ROM that has that, is regularly updated, and has a lot of bonus features too http://forum.xda-developers.com/showthread.php?t=1778010. I a currently running it. I have an OTG cable, but I have lost all my usb drives. I have heard that it works with mice and keyboards, but haven't gotten any success with those.
I have this installed: https://play.google.com/store/apps/details?id=hu.sztupy.android.usbhostcontroller
i don't know if you need it or not, but i think you do.

Charging port broken, need to backup data before factory reset without cable, how?

Hey Guys,
So a few weeks ago, my GSM Galaxy Nexus stopped charging. I used a toothpick to get the lint out and moved the pin a little bit up and slowly it started charging again but now has completely stopped no matter how much I play with the pin. I bought an external battery charger and another pair of batteries and am using those currently to run my phone.
However, this is a huge pain in the ass and I want to either get it fix or sell the phone. Before doing so, I must backup all my data and wipe the phone clean. Unfortunately, since the port doesn't work, I cannot transfer files to my computer via USB. Is there any other way to backup all my data?
Thanks!

Thanks dude that works perfectly! Is it possible to root my device once I've factory reset it over wifi as well? I just need to transfer the files over right? It's probably better to flash 4.2.1 to extend my battery life?

[Q] AFTV USB Storage issue *SOLVED*

Anyone had issues using a usb stick?
Trying to free up space by moving apps but box does not seem to acknowledge it being connected. Cheapo 16GB stick. works fine in my PC and on phone and tab using OTG cable. Has been formated. Deleted all partitions, created new primary, then formated again. Still nothing?
Just called Amazon Cust Services who took details to pass to tech support who will contact me within 48 hours.
Any ideas folks?

Not sure. But USB 3.0 flash drives are getting pretty cheap. You can pick up a 32gb sandisk ultra for about 15 bucks at Walmart or 16 for $10. If you don't mind waiting, I'm sure you could find them even cheaper online.
Its not really a solution but the faster the better. Have you done any basic trouble shooting? Maybe remove it then reinsert and wait a couple of minutes? Reboot with USB in, reboot without then insert...if using a hub try it without.
I haven't had any issues but I'd be surprised if aftv mounted every flash drive on the market. That's rarely the case on other devices. Good luck.
*I don't think the format matters. Aftv should automatically format and prepare the drive.

Thank you for your time pal. Had done reboots but not with USB in or checking if makes a diff plugging in when off then turning on. Thank you for that will give it a go.

You may want to check in Developer options. I think if you have ADB Debugging or Unknown Sources (can't remember which one) enabled it won't recognize the usb port. At least that was the case with the latest firmware.

BOOM!!!!! Solved. Turned all dev options off and it recognised it straight away. Will check them one by one later on. Thank you good sir!!!!

OTG doesnt work.

Hi guys.
First time I bought USB-OTG adapter from China and tried it, it didnt work for me. I guessed that cable is incorrect and bought another one at shop. CheckR is said that all okay, but it still doesnt work with any flash card.
So I have 2 adapters Type C - USB A, 2 different flash cards, I tried exFAT, NTFS and FAT32, it just connect and disconnect a thousands times but doesnt mount, I could see USB1102 at explorer sometimes but it unmount in 1 second. Any suggestion about it?
I feel sorry about my English, if u cant understand, pls ask me.

Agree. It sounds like a bad cable. Try this one: http://www.amazon.com/gp/product/B00XHOGEZG?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00.
I tried a different one before this and had to send it back.

Reviews seem very hit and miss on that -- lot of folks saying it doesn't work with the 6P. Frustrating. I can't find a Type C OTG cable on amazon that has consistent positive reviews, and Benson seems solely focused on A-to-C cables.

I have a type C adapter that takes an micro SD card and it is working great with my Nexus 5x.
Have you tried opening settings then storage?
With my old Nexus 5 I used StickMount an app by Chainfire to access OTG. MM supports USB but unlike StickMount I couldn't locate my OTG device with my file manager, opening settings then storage I can access OTG.
Just installed StickMount and can access my OTG device with my file manager, so StickMount does work with the Nexus 5x. My preference is using the OTG support built into MM, rather than StickMount.
Hope this is helpful, good luck.

So guys, I have already installed StickMount. I tried once more and it mounted as picture store I saw my files but it been unmounted in 10 seconds.. I think that problem not in cable coz there are few good reviews from n5x owners.
