I have a problem with detection of my ADATA S102 PRO 64 gb usb 3.0 flash drive formatted in NTFS. Device detects it very, very randomly and most often after a long period of time, or for the most of the time, never at all (5-10 minutes of being plugged in over OTG cable, but still nothing). The funny thing is, that s3 detects 4 gb flash drive (in fat32) and 320 gb hard drive (in NTFS) just fine. I wait 1 to 5 seconds and "Easy OTG Checker" program detects it (show its name) and "Nexus Photo Viewer" starts automatically as well. But my 64 gb flash drive almost never boots. I followed some troubleshoot guides, to insert OTG and USB into the device, and than re-boot it, while cable was still plugged in. Well, I tried this and USB was found. I though to myself "Thats it. I just have to reboot it when I want to use USB", but after second time, USB never mounted again. Even when there is no cable connected, "Easy OTG Checker" program still shows green check mark. It should show red cross, but it doesn't. It shows green check mark, and under it, it says: "Detected USB device: (Unknown), or "Detected USB device: Comneon HSIC Device".
You must be thinking now that this USB is not compatible with OTG standards. But you are wrong. My nexus 7 2013 detects this drive in less than 1 second. The moment I insert OTG cable into my nexus, "Easy OTG Checker" detects my USB drive as: "Detected USB device: ADATA ADATA USB Flash Drive", and when I remove it, it shows red cross as it should.
Now you must be thinking that my s3 can detect 4 gb drive and 320 gb drive, but for some bizarre reason, it cannot detect my 64 gb usb flash drive.
You are now 100 % confident to know what's wrong with my s3. It is USB 3.0 right? Both other drives are usb 2.0 so it is logical that my 64 gb drive wont work because it is 3.0 drive, and nexus 7 detects it because it is newer and better and stronger and bigger. Right? Right? But what if I told you that my friend has the same s3 as me, and when I tried the same OTG cable and the same flash drive, it detects my usb in a second. "Easy OTG Checker" detects it in a heartbeat.
I have read every possible thing related to this, every google post, every forum thread, every youtube video and I still didn't find anything related to this problem or even close to it. When I was on original samsung 4.1.2 rom, when I inserted my 64 gb usb flash drive, it showed red cross (not for 4 gb or 320 gb drive, only for 64 gb one). But when I installed cyanogenmod 4.4.2, SlimBean 4.3, and now stock samsung 4.3, it started this "Detected USB device: (Unknown)" or "Detected USB device: Comneon HSIC Device", even when no OTG cable was detected. But this message doesn't really mean anything, because it changes the moment I connect 4 gb or 320 gb drive (because it actually detects those USB's).
If anyone has any idea what could be wrong, please share it. Anything.
Thanks
tldr: My s3 detects 4 gb usb stick and 320 gb hard drive, but does not detect my 64 gb usb stick even though my nexus 7 2013 and my friends s3 detects it just fine.
update:
Today I tested this 64 gb stick on Sony Ericsson Live (yes, a phone from 2011), and "Easy OTG Checker" detected it. It said: "Detected USB device: ADATA ADATA USB Flash Drive" just like on my nexus 7. Device was on original sony rom 4.0.4 Ice Cream Sandwich.
I also tested it on nexus 5 with latest 4.4.2 kitkat and "Easy OTG Checker" said the same. It recognized the stick and mounted it perfectly.
Come on guys. No clue what could be wrong ? I know that it is a very strange case, but is there really nothing I can do to fix this? I don't know what to do anymore.

I have a Samsung Galaxy 10.1 running honeycomb 3.1 that I recently purchased the USB adapter for. I have a 250GB external hard drive formatted in FAT with its own power supply, however when it is connected to my tablet android recognizes the hard drive but none of the several file reading apps I have tried recognize it. Any ideas?
Thanks.
i guess the adaptor could only read up to 32GB of space and it should be fat32 so I can tell u to try to partition ur hard drive to 32GB parts its annoying I know but its better than nth wish this helps... I want to try so after I finish my vacation so u can try and report back..
Edit : some say they got the 1TB to work by making sure its a USB cable virgin 2.0 u can read more here

Hi i had the same problem with my external hard drive.
Every time i connected the drive it to say a usb device was connected and then attempt to open the mY files file manger. I would brefily see the file stored on my drive and then i would get the the usb device was unexpectedly disconnected.
heres how i over came that problem.
1) plug the external hard drive SG 10.1. usb device was unexpectly removed error will be displayed.
2) turn off the SG 10.1. do not unplug your external hard drive
3) turn on the Sg 10.1
4) open my files file manger and all your files should now be displayed in
storages/usb/sda
have fun it would appear there is some bug in my files or the mounting of the external hard drive but this is beyond me.
hope someone can fix this.
BTW.
I am running my sg 10.1 unrooted with stock firmware and touchwiz
Hi,
Does any of the roms like Cyanogen support USB Host mode?
I am currently using the latest version of the Cyanogen ICS-themed ROM and I tried connecting USB Hard Disks and USB Flash Drives to my Atrix through my (powered) dock but it doesn't work.
Both hard disk and flash drives were formatted to FAT32.
Nothing happens at all when the hard disk is connected.
When the flash drive is connected, it just goes "Preparing SD Card - Checking for errors" in the notification pane. I tried waiting for a while, say 5 minutes but nothing else happens.
I went to /sd-ext and it is empty.
I tried connecting a mouse and keyboard and it works fine though.
Any advice?
how do i enable the OTG mode on the Galaxy SII running android 4.0.4 (resurrection remix ICS 1.8 ROM) and i have a kernal that claims its working with OTG ( http://forum.xda-developers.com/showthread.php?t=1574672&highlight=otg ) but when i connect my cable and usb stick ( tried other devices) nothing happens! any help would be much appreciated
I just acquired a 'micro-B USB OTG' cable myself (a cheap knock-off from eBay).
As far as USB drives are concerned, I have found that I must insert a USB thumb drive into the cable before inserting the cable into my GS2. Otherwise it will not be recognized.
When inserting the cable + thumb-drive I get these two messages:
"USB connector connected" immediately followed by
"USB Mass storage connected"
and I am able to use the USB drive.
I have successfully been able to connect a 1 GB Kingston DataTraveler II, but - oddly - not a 4GB Kingston DataTraveler. An unmarked 8GB USB drive was also recognized.
I have not been able to connect: a Microsoft Comfort Curve Keyboard 2000 v.1.0 (not that I need it, but just to see if it would); and neither an HP mouse. For previous versions of Android (before ICS) you can easily find information of users successfully connecting all sorts of things including keyboards, mice, and larger hard drives.
A few other important issues are:
- File format for drives must be FAT32
- Before removing the cable+drive, remember to unmount drives by opening the notification area and click on "USB mass storage connected".
that helped me out.....not what so ever.
what is OTG btw?
On-The-Go, lets you plug in USB devices like mice , keyboards, and usb sticks into your phone like a computer

If the USB is partitioned as FAT32 a nifty notification will show and you can press that and then browse.
However, if the USB is partitioned as NTFS, you should open a file manager with root access (Root Explorer or ES File manager to name a few) and browse to /mnt/ntfs/ and you should see your files there.
Note: Am only assuming this is the mount point, since looking at the kernel you are using, he mentioned gokhan for the USB OTG and I am using his kernel (Siyah)
Hello to one and all I would like some assistance with regards to a very popular issue with many so called solutions and apps which I believe shouldn't be considering any OS should be able to handle any filesystem.
The device I am using is a Phablet with Android 4.2.2 kernel 3.4.5 and the Hdd is WD My Passport 500GB Portable USB NTFS, I have rooted the device using Framaroot checked with Root checker to make sure and followed the many suggestions using app after app to no avail. When I connect the hdd to the device the light on the hdd is forever blinking making a sound as if it is trying to work but nothing happens and in the upper left corner damaged usb needs reformatting appears.
When I connect a normal Fat32 4gb Usb stick with the cable I use it works perfectly, which is the same cable I got with an older tablet with android 2. something when tablets were fairly new to the general public which worked with my usb hdd then. I have been using a kindlefirehd which has no Usb capabilities ever since so never got the chance or looked into getting the hdd to work with any other device until now. Is there any solution for this device or should I give up trying?
Please Help!
Thank You!
I've been wanting to ask this for a while now. I have a USB OTG for my Galaxy Tab 10.1 and it's able to recognize my 1gb and 4gb drives. However, when I try my higher capacity 16gb and 32gb drives it says "high powered device connected" and doesn't open them like it would on my lower capacity drives. I read somewhere that Android is only able to recognize 4gb usb drives with a FAT file system. Not sure how true it is but my tab has 4.0.4 ICS stock rom on it. Also, it doesn't recognize my wired mouse and says it's also a high powered device.
Anyway my focus is on the flash drive. How do I make it recognize higher capacity drives? And can anyone recommend brands that work? Thank you.

Try this hack. Instead of inserting the OTG first then the USB, try it the other way round. The USB into the OTG then the OTG to tab. Or just install a new ROM.
