Where is this at for the tab. Has anyone found it yet. I dont know if maybe froyo does not support the usb host mode needed or what. I saw that it was comming and yet cannot seem to find it. It was supposed to plug into the data port on the tab and give you the ability to attatch regular usb peripherals.
Any info is greatly appreciated

FWIW I saw a USB dock at Home Plus (Tesco for you guys in the UK) the other day for 29,000 KRW. Although I can't be sure, it appeared to be just a USB only dock but it looked like the HDMI dock recently reviewed on here.

you should try out the Elan Mobidapter, it's a micro SD to USB adapter with integrated USB Host. i'm using the Mobidapter often and im happy with it, but you can only use USB Storages with it. No keyboard support.
BTW: Android itself doesn't have or support an USB Host.

That's not entirely true. Most android builds don't have the necessary usb host support as part of the kernel, but there's nothing to prevent someone from compiling it or adding it in as a module. The Tab is/was supposed to do this OOTB, and based on the pinout information posted elsewhere, there is at least kernel support for determining if host mode should be enabled. With a modified iPod connector from Sparkfun I was able to get the Tab's AccessoryManager process (I think that's what it was called) to see a non-supported device plugged in (externally-powered USB hard drive enclosure), even if it couldn't enumerate it. It could be because I didn't connect the requisite +5V for downstream devices, or because there is no usb_storage module available. More testing needs to be done on this before we write it off completely. Hopefully Samsung will just release their solution(s) sooner than later.
That is what I wish they would do. But im afraid with the tab10.1 it may be put on the back burner

How did you modify the ipod connector? I have a few ipod/iphone cables lying around but they seem backwards compared to the sgt connector and difficult to modify.
I'm thinking about buying some sgt connectors or cables from china to play with.

Unfortunately I could not find a supplier of the "mirrored" iPod connectors that the SGT uses. I contacted many China-based component mfgs and none could point me in the right direction for that stupid dock connector. So I got the iPod one from SparkFun, used an xacto knife and small file to grind off the material on either side of the connector that keys it into the mating iPod connector. This allows you to invert it and plug it into the SGT, which then gives you access to all 30 pins. The cheap charging/sync cables that you can get from ebay and the likes only come with 5-7 pins connected, and the rest missing.

you know what sucks? I had a $100 haipad that had a microusb jack and came with a 6" adapter cable. guess what? you could plug in usb sticks, a usb mouse, or a usb keyboard. worked perfectly. mouse had a pointer, keyboard worked without a popup, it was all quite magical.
that was on a 2.1 resistive touchscreen chinese tablet.
why the hell can't the tab to this?

So I built a USB OTG adapter by shorting the ID pin to ground on the USB connector. This makes the Note go into host mode and start providing power out so it can talk to memory sticks and mice and keyboards.
Can I somehow through hardware or a custom kernel charge the note while in Host mode?
I want to build a little custom circuit for my Note that lets me charge it while in my car cradle but still talk to various USB devices like my OBDII adapter.
Yeah, nerdier than most Q&A, I'll try the development section if I do not get an answer.

I'm modifying an HP Ipaq keyboard from its ipaq interface to micro USB for my Note. I'm planning also putting in a powerpack and tiny powered USB hub to make the power connection.
If you got a small USB hub and gutted it then would that help?

Dude, there is a small (but non-zero) chance you could permanently screw up your note doing what you describe (which is why I am asking the question instead of just hooking up a power supply and seeing what happens.
Most likely, nothing bad will happen but it won't work. You'll have two voltage sources fighting each other trying to push current in opposite directions but the relative difference in voltage will make for very small currents.
Worst case is you will fry something in your USB OTG chipset by shoving current into a system designed to push current out.
Second worst case is your battery pack goes boom because the Note is pushing current in to a regulator trying to push it out (unlikely).

Hi everyone.
I'm about to buy a powered USB hub with 4 ports... it's a hub that draws its own power from a wall socket, so it doesn't have to draw current from the Galaxy Note.
Would it work? I'd connect it to the note via an USB OTG cable, and plug it in a wall socket... then connect my A4Tech mouse and flexible keyboard (both wired, of course) to it... It should work, right?
For what it's worth, the USB Hub I'm going to buy is this one. Not really famous . Oh yeah, the page is in Romanian language...
Just did a google search and found these.. Link, and link 2
So i think it should work..

Saw that video... was surprised to see an external storage device works in parallel with a wireless mouse receiver! Didn't know the latter would even be supported!
Oh well, I've seen people saying that the S2 provides a bit more power through OTG... hence it would work with multiple devices.
Guess I'll see for myself tomorrow... will get a chance to test the hub before I buy it. Fingers crossed . I'm one step closer to turning my phone into a real computer, haha .
If it draws power from the wall socket it means that your portable hard drives should work as well.

No matter the hub... It just needs additional separate power. Okay

Alright, so I bought an USB OTG cable and the above mentioned USB hub.
The USB hub has one mini-USB port, one 5V power supply port, and 4 different USB 2.0 ports.
I have a lot of Nokia chargers... neither fit in the 5V power supply port!
So... since I don't own a USB 2.0 A-A cable, I cannot connect the hub to a mini-USB charger and the OTG cable at the same time.
I figured I could use a USB 2.0 A-A cable to connect the OTG cable to one of the 4 ports of the Hub, while it is drawing current from a mini-USB charger, but... I don't have such a cable.
I'll return the USB hub tomorrow.
I found a PlayStation 3 bluetooth keyboard which also has a mouse (tiny track"ball") and I think I'm going to buy that...
I wish there were USB hubs with their own power adapters / chargers on the market... that would NOT cost $100 .
Yup. I'm done.
I returned the USB Hub, and I sold the USB OTG cable to a friend (instead of returning it to the seller, who would probably be stunned by the fact that I'd have wanted to return such a simple thing, lol).
I guess I'm done with these sorts of things, at least for the time being.
Instead of hooking up a mouse & keyboard with insanely long wires and get entangled in them and choke myself to death... (if I get to make it work)... I'll rather buy a $30 PS3 bluetooth keyboard with a mouse track"ball".
Oh well...

Any help would be appreciated.
I found this on the bay : item # 140839631580 (Can't post link I'm too new... I was a lurker for a while -_-)
i didn't think the N7 could support power and OTG
You want it for video or audio? You could try a wifi solution for audio. Or be the guy that gets the pins to work.
there is NO data and charge at the same time. This is due to how the device switches from charge to usb mode thru the pin 4 . it senses rather a data cable or charge cable is being used . will not charge via otg..
there are several threads with experiments trying to get this work .You could use a wifi or bluethooth drive for data...
I have no clue what im doing but this is what im playing with at the moment. Its a old dock for sgs2 i believe but it has a dc and usb input on the back of it.
Im about to this because i have very little patience for china.

Would get the cheaper one but the juiced one has a flexible cable vs the fixed usb on the other one. Would this be pointless though?
Unfortunately OTG sends ground up the sense pin to trigger host mode. Once activated it sends 5V DOWN the USB cable to power your USB devices. Trying to send voltage up the cable at the same time to the Nexus would not be a good idea. The only way around it I can think of would be to hack the firmware to only activate the data pins in host mode and keep the power circuit seperate, then you could power the USB device from a modified dock/hub which sends power up the USB cable to the device.
A lot of work, and without the powered hub, OTG would be useless!
In the long run wouldn't it be easier to just plug in the power lead when needed and have the otg in the rest of the time? (or vice versa). It would mean you having to have easy access to the usb port but I can't see an easy non technical solution to connecting both at once.
Don't use the Nexus 7 for a car install. You can get an Acer Iconia A100 with a full-size USB port to connect to whatever external storage solution you want, and it's usually about the same price or cheaper than the Nexus 7.

Same principle. In normal OTG host mode the tablet powers the peripherals. A USB keyboard/mouse will be no exception to that.

Ofcourse there is charge and otg at the same time by just simply shorting pins 4 and 5 with a resistor,in my case for xperia p , a 100k resistor does it.
Timurs USB ROM from another site is what you want. Has links and everything you need.

Hello all. Planning to get a MHL 2.0 cable for my note 3 but I also want to hook up a keyboard and mouse. I have a logitech k/b that uses wireless signal via a USB dongle. I figured the OTG cable would suffice but naturally once the MHL cable is in, there is no way to also use the OTG cable. Curious if there is some sort of hub that allows at least 1x micro usb and 1x full size usb, or some sort of splitter? I realize a bluetooth keyboard and mouse is probably another solution but would prefer to avoid if I could.
Thanks!
