Do you think that will work for Mass Storage as well? I bought one off ebay for 1.49 so we can try it out. Hopefully it will come before friday morning so i can test.

Didn't thought of that, I'll try it out tonight.

If you're just taking the USB cable that came with the tablet, changing it's gender and plugging something into the end, it won't work. The tablet would need to have USB Host support which this tablet does not. I believe that the Samsung USB Adapter that converts directly from the Samsung Connector to USB Female will add USB Host support (USB OTG).

All 3.1 are USB host. However, the female to female adapter doesn't do the trick.

I'm sorry, but you're wrong. Honeycomb 3.1 adds SOFTWARE support for USB Host funtionality. The device has to have HARDWARE support as well. This tablet does not. That is the reason that you need a special adapter that provides USB Host HARDWARE funtionality, such as the one I listed above.

I've got my fingers crossed Samsung hasn't dicked up the Bluetooth stack on the Galaxy Tab 10.1/8.9:

Sorry to dig up the old thread but did anyone get this to work? I would love to play emulators on this tablet!

Yes. There's a lot of misinformation in this thread. The tablet DOES have USB Host capability, but it will only enable it when it sees a specific resistor on a particular pin in the dock connector.
http://forum.xda-developers.com/showthread.php?t=1155065 for more details.
To get USB Host, there are two approaches:
1) Make your own cable with the correct resistors
2) Purchase the Samsung USB Host adapter which is now available for around $20.
Note that there are some limitations:
1) Xbox360 controllers and PS3 controllers are not standard HID devices and require kernel support not present in stock kernels. Pershoot's kernel has the necessary modules.
2) PS3 controllers must be fully charged before trying to use them. If not they will try to charge their battery from the tab and cause an overcurrent trip, disabling the port until the USB dongle is disconnected.
Also, Samsung didn't mangle the Bluetooth stack like they do with their phones, so wiimotes work.

Not working for me
Not sure if there's a specific USB setting, but I bought the adapted and it works with Chainfire's DSLR Controller no problem. I plugged in the playstation 3 remote and had no luck, nor any detection of the device. Tried running an n64 emulator to try to map the keys, no luck there either.
All of the guides seem to be using a Xoom, I'm on the brand new OTA on the GT10.1
Anyone else?

USB Adapter for Galaxy tab 10.1
Verizon wireless corporate stores have the adapter in stock they will have to order it but last time i checked they had about 4000 in the warehouse, I hope this is helpful for those of you who are patiently waiting.

Which kernel are you running? Did you read my notes in the post prior to yours at all?

So, if i get the official USB adapter my regular wireless keyboard (Logitech Wave) should work seamlessly. Right?

I've just been using the "SixAxis Controller" app from Dancing Pixel (you can find it on the Android Market) to connect my PS3 controller to my tablet over Bluetooth. It's worked great for me (note: I use yongzh's emulators)
Hope that helps with the PS3 issues...I don't really know much about the USB adapter as I don't use it.

USB host cable for $5 on Amazon with Prime (works)

So, this works:
http://www.amazon.com/gp/product/B005FUNYSA/ref=oh_o00_s00_i00_details
However, it doesn't work for everything. A mouse works, but a USB Flash Drive doesn't seem to work, nor does another USB device that does work on the Acer A500 Android tablet I have.
So... Yeah. Just thought you guys would wanna know. I'll look into more devices. I know Honeycomb supported all kinds of USB devices (hub, flash drive, mouse, keyboard) so I'm a little surprised the flash drive didn't work. I'll let you know if I find anything else out. Might just be a driver issue we can work out with custom ROMS. Obviously the communications is working since the mouse works. It could be a power draw issue. I have a USB power meter and the mouse draws 20ma. The flash drive that doesn't work draws 60ma.
-Taylor
UPDATE: Works great with a device we are developing at work (basically a USB hub and FTDI chip combo board if that means anything to ya). It draws about 62ma, so the flash drive issue must not be due to power draw.
UPDATE 2: Rooted users can easily mount flash drives using the app StickMount in the market - its very clean and works well! Thanks to user [esoomenona] for the suggestion.

For who lives outside the USA, buy this with international free shipping: http://www.dealextreme.com/p/usb-fe...a-cable-for-samsung-i9100-galaxy-s2-5cm-67186
The only cons is that can take a while to arrive.

Actually it looks like no. One of the reviews points out its not a USB OTG (On the go) adapter. USB On the go is a USB port that can act either as a device (plug it into your computer) or as a host (plug in a mouse, etc). In order to tell the phone which mode to be in, USB OTG connectors need to have one of the pins hooked up to ground. Unfortunately not all of these adapters do (I have no idea what they're good for if they don't) and it looks like that one doesn't. But someone linked to the one on DealExtreme that might work.

Shoot, I paid a little over four bucks for that same one from the same company, on Newegg. I should've looked at Amazon as well. Oh well...

Okay, so I received the cable I stated above, and tried to plug in a microSD card via USB adapter, and it didn't work. After a bit of googling, I've come to think of two options for why it doesn't:
1. The cable doesn't work
2. The OS doesn't seem to mount them automatically. I found an app called StickMount on the Market, but it requires root, and I haven't rooted yet.
Anyone know anything about this?

Well I mentioned in the first post that USB flash drives don't work. A card reader is going to have the same issue, as they're basically the same. I think its related to the phone not having its own microSD card, and so it lacks the drivers to mount storage properly. Which still seems silly to me if the device has USB host support, they should include those things!
Plug in a mouse. If a mouse works, the cable is fine.

I honestly think this is going to be it...because of internal storage it doesn't come with the native ability to detect external storage. I'd imagine that app would allow it or that it'll get pushed out as an update down the road...maybe a MOD will get made too if it takes too long.
Either way, when mine comes *crosses fingers for tomorrow* I'll be rooting and post back the results.

Oh damn, StickMount works! Plug in a USB drive and stickmount will pop up asking to run. Then it mounts the drive and my file browser sees it. Then you unmount the drive before unplugging. Wish it was native but this is pretty damn simple. Thanks for finding it!
I was a bit skeptical since the USB drive doesn't even light up when you first plug it in, but once you run stickmount its all good!
Go ahead and root that thing! Just note rooting will erase the phone, so back up first!

I had a Micro USB to USB female for my Nook Color for UBS host. Tried it. Worked like a charm. It even drew enough to power a hub, the keyboard, and the mouse. I was shocked. Im going to but a splitter and use a MHL out to HDMI for 1080 goodness.
Got mine on Amazon for $1.46. Works well (I just wish it was a cable and not a plug though(.

I'll have to see how this works out, ordered the cable.
I have an externally powered USB hub that I can plug into the USB OTG cable.

This is great, I've been looking for these cables. Thanks!
Edit: Does anyone have any idea if you can use an MHL adapter for HDMI at the same time as one of these? I see that some MHL adapters have charging ports, but I don't know if they support data.

Using MHL through a splitter won't work based on how MHL works. You either get USB or MHL. MHL does not use USB-compatible signaling.

Alright, I typed this with a mouse and it's slow, but cool. Guess it's time to root. See you on the other side.

How to make OTG work?

I bought a micro usb to female usb adapter and I've tried using Faux's kernal, Da_G's .42 kernel and Bullet 2.9 but plugging in the adapter with any usb does not seem to work.. is there any app I need or like how do I verify that it works?

Nope it should work right away. What are you trying to connect? Also, it's possible that it's a bad adapter.

YOU NEED AN ACTUAL OTG CABLE, NOT JUST AN ADAPTER.
Yes all caps, this has been stated time and time again, some people have had luck with the i9100 cables , some have not, you need a cable that works with either the t989 or Hercules, but, I have tested one that was made for the Xoom and it worked as well ...

Well I bought it online and I'm assuming it was made for OTG because what else could you possibly use one for? idk maybe there's another use for it but I can't think of one.
I read something online about shorting the 4 pin to 5 or something, could that work?
And I've tried connecting 3 different flash drives

Yes that could work, that is usually what a OTG cable does, but depends on the phone, the regular adapters are used, to use an Mini USB cable/charger on a Micro port , I use them all the time, because I have dozens of older chargers ....

Ok so I ripped open the adapter and the build quality was too good so I had to just rip the heads off lol so now I have a micro usb end with no wires connected and a female usb with no wires on it. Can I take 5 thin wires and connect the appropriate pins on the micro usb end to the corresponding pins on the female one?
If anyone has a guide to do this, it'd be appreciated

2. TF(micro SD) socket
3. Standard SD socket
4. micro USB power in.

Guys, I have a question a little bit off topic here.
It is possible to use a keyboard with Gnex using an USB OTG adapter?
And if it is possible to connect the Gnex in the display using the HDMI adapter, while the keyboard is plugged through the OTG adapter. trying to make it easy: gnex plugged in HDMI adapter, HDMI to the display, in the connector that we usually plug the charger I will plug the OTG cable with the keyboard in it.
If this works the battery will run out fast as hell, but I don't know if is possible to do it.

No you can not have HDMI adapter and OTG at the same time.
Bluetooth is your best bet. I got a logitech bluetooth keyboard and mouse made for tablets and have a nice case for the keyboard that turns into a stand for your tablet and phone. Also if you have bluetooth on your pc like i do, i use it for that too
Here is the keyboard I got: http://www.amazon.com/Logitech-Tabl...501&sr=8-1&keywords=logitech+android+keyboard
Mouse: http://www.amazon.com/Logitech-Tabl...501&sr=8-2&keywords=logitech+android+keyboard

Why did you post this without a link to where you got it? I don't see this card reader for sale anywhere when I searched for it.
These are my thoughts on OP.

Thanks man. I'm avoiding bluetooth stuff. Too many things to charge in the end of the day. So far I was able to connect a mouse and a keyboard to the gnex using the OTG cable and an USB hub. I'll lock for a workaround to this, maybe a USB display or something like that.

I am selling mine, it just doesn't work good with tv's.
On my Panasonic and my Sharp lcd tv it doesn't gives full screen, the edges are cut and that sucks.
Doesn't matter what Screen settings I try, no 100% of the S3 is displayed.
Auto scale, normally is the best setting, but not working out for this adapter.
For gaming it isn't such a big deal, but when your notification bar is only half visible and the apps been cut on the aidea and bottom, that is irritating.
I looked for reviews on Youtube and you will see many people with this problem, also many where it works just fine but the problem is in the adapter or the S3 which isn't working as it should do.

Are there any settings that i have to do first if i wanna connect the phone with my tv?
Can i see immediatly the screen at the boot time of the phone? And see it also in recovery or download mode?

When you plug in the adapter and connect it with the hdmi cable you will directly see the it, there are not settings for the mhl cable on the S3

Latest idea is hooking it up to an MHL enabled tv(meaning power coming this way) and use the USB port on the adapter for otg.

Well that ain't gonna work, the usb has only power as far as I know...
So you can try that, but the MHL adapter is not designed to use it like that. It needs the power via the usb connector.
But maybe, maybe you can get power via tv...

Yeah, newer TVs are designed to charge via MHL, though not sure if the official Samsung adapter supports it.

If you have an MHL enabled tv, the power comes from the tv so the USB on the adapter doesn't need to be used for power, hence I said you could try to connect and otg cable there instead.
It you have an MHL enabled tv then you don't need an adapter but just a cable like this instead

I know, but I don't think the charge port will work as otg....
As far as I know it is only for charge, and doesn't have the rest of the usb working.
I even doubt if when it has a full functional usb port, MHL allows to use MHL both with usb on the same time...
