Hi there.
I got my Galaxy S3 about 3 days ago and love almost everything about it.
I've been experimenting heavily with USB OTG, and it's such a great feature to have. I have got a Mouse, keyboard and USB flash drive all working over the USB OTG cable. I can also get the Mouse and Keyboard connected at the same time over a USB hub. However, USB flash drives refuse to work over a hub on USB OTG, even though they work directly from the phone to the USB. This is pretty confusing to me, considering two higher power devices work over the hub.
I've tried two different varieties of hub, both giving the same result and have also tried two flash drives. I'm using an un-powered hub and I honestly don't see how just because I'm using a hub the USB Flash drive isn't working. There is no way that it can have a higher power usage than a mouse/keyboard at the same time.
Just to note, I'm using the hub unpowered externally, it's going directly into the phone. I can't seem to find the power cable to try.
I have the UK (GSM) variant of the phone in blue and am running on the Stock 4.0.4 ICS firmware (i9300XXLF2) and haven't tried to root or anything.
Could someone suggest what might be the issue I'm having, or some things to try?
Thanks

Today, a friend asked if I had an extra laptop. He needed one for his 10 year old son.
While rummaging through my closet (you know, the one with all the old computers, shotguns, and half empty Jack Daniels bottles) when I found one of these.
Two Pics … http://db.tt/GY4wfof6 and http://db.tt/rzkodoMi
Now, I have no idea as to how, where or when I got this. I had to search the net to even know what it was.
Ebay link … http://www.ebay.com/itm/230328510631?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2648
Continuing my search of the closet I also found a 2.5 inch 160 gig IDE hard drive. Assembled the two and I now have a portable battery powered drive that works great with my Flyer.
That looks kinda old school. =)
So you connect to the flyer via bluetooth or microUSB?
It connects with microUSB.
Now that I’ve had a chance to use it a while I’ve found I can set its switch to PC or DC.
When set to PC I just plug it in to my Flyer and can copy files both ways.
When set to DC it will function as a standalone unit (because it has its own battery power). I can plug thumb drives and USB sdcard adaptors into it to move files both ways.
It will even plug into my camera and copy the pictures.
Kind of handy as the Flyer doesn’t supply power at its microUSB port to spin a hard drive.
It’s not what I call well built but seems to work.
At least it does the job! I didn't know we could use OTG harddrive for the flyer...
That's very cool. Vastly increases the number of movies I could take with me on a long trip!
ARRR
Ok so spent about £40 on one of these and it doesn't work with my Flyer(32GB WiFi 3G). Flyer is not rooted and running the latest official version of HC. I have tried both DC and PC but device still does not detect the OTG drive. My samsung mobile finds the device fine.
Are you using a standard micro usb cable ??

Yes using a standard micro usb cable
Try this ... Shut down your Flyer (make sure Fast Boot is unchecked in settings) then turn on your drive in DC mode and restart your Flyer.
Your Flyer should find it then and will work from then on.
Using your file explorer of choice you should see a new folder called USB
Hi, tried this but still no go. Ran a USB host and USB OGB diganostics app which still fail to detect the device. The drive works with my camera/Samsung phone and brothers PSP. May have to fork out for WIFI drive.
Still no go with the OTG device. Tried with a friends Flyer and same results. I am going to try this device, is fairly cheap.

Strange … My Flyer is the 16 Gig Best Buy wifi model and is rooted I wonder if that makes a difference
I use an OTG USB cable on my US BB Wifi Flyer , the standard usb cable doesn't work for me.

I have an OTG cable from my samsung but this did not work. what OTG cable are you using? I gather you are connecting the USB device into the OTG cable via a powered hub?
Got it working but it's a hackjob, was going to root but having to downgrade then upgrade again was a pain and was not guaranteed to work. Tried running the OTG cable into a powered hub but for what ever reason would always come up USB device not recognised when plugging in any memory device. Tried 3 USB hubs with the same result. Ended up cutting up an OTG cable and a few other USB cables so I could provide power to the device and then power to the tablet as well. For whatever reason i need to provide power to he memory stick before plugging into tablet. I have tested 4 different memory pens and 1 external harddrive and they all work.
I just bought a generic OTG cable, its about 6 inches long. I think it may have come from HP. I have used both a powered hub and a y-usb hard drive cable and both worked for me.
You have to have power on the device before you plug it onto the FLyer so that on connect the Flyer software knows what type of device it is and can load the driver. Otherwise the Flyer will label it unknown and disable the device.
Managed to get USB on the go to work on my Jetstream. See the following post. as the flyer very similar, should work for flyer too.

Its a common IT issue that not everything works through a USB hub. Or even US extension cables.

It works through it regularly through a PC.
Both USB sticks. And I've seen a video of someone doing it on youtube. I've also tried both FAT32 and NTFS with the same result.
Can you explain your exact set up please?

Samsung galaxy S3 connected to a small unpowered USB 2.0 hub, via a standard USB OTG cable. Connected to the USB hub is a single USB flash drive of which I have tried a 16GB (14GB actual) stick formatted in FAT32 and a 128mb stick in FAT32. When I connect the OTG cable, it's recognised by the phone. I then attach the USB hub and nothing is recognised, but it is infact working. I can confirm that because I've tried both a mouse and keyboard separately and at the same time through the hub. I have tried another hub with the same result. I then unplug those and put in the flash drive, the red light on the flash drive flashes for a bit and then dies, nothing is picked up by the phone.
Is the hub connected to a PC or not?
Are you saying:
Flash > Hub > PC it works
Flash > hub > Galaxy it does not?
Dont forget a PC USB kicks out 500mA of power which is about the minimum a flash drive would need. If the PC is not supplying the power to the USB via the Hub, I doubt the galaxy could supply that much.
Can you power the hub using the PC?
Yes, that's what I'm saying.
The hub works with the galaxy, but USB through the hub does not. I can connect a Keyboard and Mouse (Both with lots of lights on them) at the same time to the hub on the galaxy which SURELY takes more power than a single USB.
Everything works through the hub on the pc, and most things work through the hub on the galaxy but not flash drives.
So:
Keyboard + Mouse > Hub > Galaxy it works
Flash Drive > Hub > Galaxy doesn't work.
That's why I'm so confused. And power is going to the flash drive, the light turns on and flashes for a while, but is not picked up by the galaxy. The usb flash drive also works under normal circumstances directly through the OTG cable.
Human input devices take next to no power. A USB flash drive needs More. I believe this is your issue as previously mentioned

Seriously?
How come I can't just use one USB on the hub then... I'm only plugging one device into the hub, surely that should just be extending it? Or does it constantly try to power all of the ports? Is there any way I can debug the USB port on the galaxy? Or even limit power to just 2 out of 4 ports?
EDIT: I just read that a micro usb port is generally rated for 500mA+, which explains why the usb works normally, is it just the fact that all of the ports are powered?
MicroUsb is rated for 0.5A, that's correct.
However Usb-to-go is not rated for any output power, only for a list of compatible devices.
It may or may not work with other normal Usb-Devices, and could even be damaged if the slave device uses too much power.
(Unlikely with highend-devices such as the S3)
LED's take next to no power, the keyboard too.
Modern (=optical) mice got some electronic but it's not really high either.
Usb-Hubs however take quita a bit of power and flash drives do so too (especially when erasing "overwriting" blocks).
You could try a powerd usb hub , there might even exist some with a battery pack.
If not, it shouldn't be too hard to strap a battery pack to a hub, however that makes it heavier, clunkier and requires charging...

Okay, that makes sense then.
The hub is tiny and that's the idea, if I could get a tiny battery that'd okay, just irritating really. To be honest, I could do with just two ports, it is just that I sometimes want to use my flash drive in conjunction with another device or something and it's yet another inconvenience to buy another hub.
I may buy a charging pack for my phone, because honestly the battery life is abysmal, do you reckon that I could hook that battery pack up to the hub? Although I don't see that working because the hub in question has a dedicated power input.
Is there a set up you think might work? The idea is to be able to connect some extra storage and keep it fairly compact so that I'm not lugging a load of extra crap around. The hub I'm planning to use is a tiny square, probably about 1.5inches large.
I love the idea of my phone being a mini computer, it really does do just about everything I want, that would make it even better.
EDIT: I've tried a 2 way female splitter, no success there either. I think what I'd really need is a bluetooth keyboard that I can connect to my phone, that also has a usb port I can connect a mouse to, so I can then plug in my stick and use a mouse+keyboard combo.
Hey everyone,
I just ordered an USB HUB device and I tested it on both my PC and my tablet (Nexus 7), and everything worked flawlessly (tested with mouse, keyboard, usb stick and gamepad usb at the same time and everything worked fine on both devices).
When it came to the Galaxy S2, for some reason only the USB memory stick works, while it gives power to the keyboard/mice/pad but doesn't recognize them or something.
I've tried all those separated one by one and they all work without a problem with the same OTG cable I am using for this. I also tried a keyboard/mouse combination with PS2 ports and an USB adapter into my SGS2 via OTG and both works at the same time..
Anyone knows what could be the problem here? I can't understand why SGS2 can handle mouse/mice at the same time via PS2-USB-OTG converter but not via USB-HUB-OTG, while they work for separated (and the entire combination works via PC and Nexus 7).
I checked and people reports they all work in the sgs2 too, and I can see videos with keyboard/mice usb hub working.. ¿what can be happening here? Maybe my USB Hub is for some reason not complatible with sgs2?
The USB hub I'm using is this one:

Anyone?
I'm looking to be able to use my external HDD (1TB WD passport) on my phone via OTG. As I understand, ntfs support varies with kernels etc but I'll cross that bridge when I come to it as I think there's a more fundamental problem.
I've got an OTG cable, and my mouse, usb pen drive, keyboard etc work with it. The HDD doesn't, because the phone can't provide enough power to operate the thing. I thought I could get around this by connecting it via my usb hub (which runs off external mains power) but when I connected this up to the phone and plugged the HDD in nothing happened. Likewise, the mouse and pen drive etc could also not be recognised by the phone when they were each plugged in via the hub (one at a time, I wasn't trying to run 8 things at once!) even though they worked perfectly when the phone itself was powering them when they were directly plugged into the OTG cable (if that makes any sense).
So, assuming it was a problem with the hub, I instead tried the method in this thread http://forum.xda-developers.com/showthread.php?t=1828032 and made my own y type cable so that now rather than the phone providing power to the OTG peripheral, the power now comes from a standard USB phone charger. I'm fairly confident that I did all the soldering correctly and there weren't any short circuits.
When I tried using this, I had the same issue as with the hub. None of the mouse, the pen drive etc could be recognised with the modified OTG cable, which was odd as physically nothing had changed from the point of view of the peripheral plugged into the OTG (the data cables connecting it to the phone were unchanged, and it was still getting 5V power, just from the wall rather than my phone) which makes me think perhaps the problem is a software one where the phone only recognises a USB peripheral/begins USB host mode if the peripheral is actually draining power, since the power leads running from the phone side of the OTG cable are now just an open circuit.
Just to confirm I hadn't just snipped a data cable by accident when modifying the OTG cable, I re-soldered the OTG cable to how it originally was and it worked the same way it had previously. This means all the data cables are still intact, so I think it must be a software issue.
I thought maybe a way of testing this would be to modify the y cable and connect the red and black power cables coming out of the phone to each other via a fairly hefty resistor (so you still get power flowing from the phone even though the USB peripheral is powered by the wall). But it seems a bit dangerous!
Has anyone else had trouble with this? I've read around on forums and for a lot of people USB hubs and y type OTG cables seem to "just work", although I've not seen anyone with an i9300 reporting success. I'm running the latest version of liquidsmooth, but have also tested on CM10.1 and have the same problem. It might be an AOSP thing that stock samsung firmware will fix?
Let me know your experiences!
TLDR: I'm pretty sure I've got a software issue where my i9300 only recognises a USB peripheral/begins USB host mode via OTG if the peripheral is actually draining the phone's power, and so doesn't work when a USB hub or externally powered (y type) OTG cable is being used.
Thank you!
It apparently only supports 500GB regardless of power source

Really? That's odd - is that an android limitation or samsung? Either way it still seems weird that my y cable/hub didn't work for the mouse/keyboard, is that something you'd expect?
Sorry I didn't read that part.
I have a portable passive hub. Kb and mouse working fine...

Hello! I'm using an Atrix MB860 with CM7-MROM, rooted and unlocked. I have a USB-female to micro-b-male USB-OTG cable (yes it is an OTG cable with pins 5 and 4 shorted or whatever), a powered USB hub where the red +5v line is coming from a 5v, 600mA power supply, not the usb cable, and 3 different USB OTG host controller apps.
My powered USB hub works just fine on both of my computers, so I know that its not the issue. But I can't get my Atrix, or at least the USB OTG apps I've tried, to recognize any device I plug into the hub, or even straight into the cable. I've tried 2 different wired keyboards, a wireless keyboard/mouse, an xbox 360 wireless controller receiver, and 4 different USB flash drives, and NOTHING works on the Atrix (but they all work on my PC through the same hub). I have tried restarting the USB OTG apps, I've tried pressing the 'refresh' button in them, I've tried restarting the entire phone with the USB OTG cable plugged in on bootup, but nothing works!
What am I doing wrong?! I know this phone supports USB OTG, I've seen videos of it working on youtube.
EDIT - Okay, my powered hub + otg cable combo is confirmed working just fine on my friend's Motorola Xoom tablet running stock Android 4.whatever firmware. It recognizes both my keyboard and my flash drive plugged into the hub, at the same time. But when I unplug it from the tablet and plug it into my Atrix phone, so that the keyboard/flash drive are plugged into the EXACT SAME ports on the hub, my Motorola Atrix does not recognize them at all.
What. The. Hell.
i dont think atrix does OTG. sorry mate.
Whaaat? But there's numerous threads in here about people getting it to work just fine on the Atrix!
Also, there's videos like this on youtube of it working fine on an MB860:

I think it only works on blur gb. You need nebtop.apk, so you can simulate docking the phone. That should enable otg with your powered hub
