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:

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.

MHL MicroUSB to HDMI Adapter **VIDEO INSIDE

Thanks for the video, it is really cool.
When I had my G2x with micro HDMI out, I bought all kines of cables to plug it into the TV from the comfort of my bed, and I really only used once or twice.
Maybe in the future I'll buy it but I think it will end up in my cable's cabinet.

How does this play out with USB host mode in Android?
Do I need another adapter for host mode? Or can I use this one while I also have HDMI out?
http://www.amazon.com/Menotek-Adapt...1?s=electronics&ie=UTF8&qid=1325341220&sr=1-1
This one seems to be "certified" for the Galaxy Nexus and also has a charging port to use while doing HDMI output. Does the Samsung adapter come with this?
I'm most certainly interesred but I want more details before shelling out money, even if it's small money
Edit: Looked at the video and I see the USB port there. Still though, how does this play wtih USB host? Do I even need an adapter for that?

Using the HDMI adapter and playing games with a controller can only be done with a bluetooth controller? Is there any way I can use HDMI and a USB PS3/360 controller?
(using the PS3 wireless is not a option for me i cannot get the app and phone to work together)

to ppl with questions, i got the official samsung gs2 mhl adapter. its 11$.
http://www.ebay.com/itm/230721222527?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
works wonders. i am 4.0.2 stock.
it uses full hdmi. 1$ on ebay.
it has a charging port, but it shows plugged in as usb charger even when plugged into the wall. it only draws enough power to power keep the charge constant, that is your battery does not go down, nor does it go up. and no, you cannot connect usb host when watching in mhl mode. would have been cool, but doesnt work.
One more thing, apparently THE PHONE HAS TO BE PLUGGED IN FOR THE MHL ADAPTER TO WORK. So, unless you plug in the charger, the mhl adater wont give output.
i hope i answered all questions.

OMG I need me on of these. It's not a Amazon prime item so that mean I have to pay for shipping lol.

nice!

Wow. So emulator+wifi+bluetooth+mhl= dead phone. 500ma is not enough to keep the GN floating.
Seems like a huge oversight on Google's part or perhaps it's just a MHL limitation. I know data does not work, which is why people have to use BT. But 500ma, what a joke.
Can anyone else confirm this?

Awesome video and post, thanks!!
Does the MHL to HDMI work with Android Movies? I know on my stock Transformer TF101 HDMI out is blocked in Movies. ...worked fine for Netflix and others though.

As far as battery is concerned. Would it be possible to program the screen to turn off when viewing in HDMI and still view it on the TV? seems like this would cut battery consumption dramatically. If not you could set the screen brightness to as low as possible.

Thanks man! Gonna buy this ASAP

So it looks like the only option is to use some sort of dual charging situation where one charges the MHL adapter and the other charges the phone via pogo.
Perhaps the native HDMI doc allows AC charging? I guess we will have to wait and see.

Audio Out / Charge micro USB cable

Hi there,
I'm looking at returning back to the Android scene with a nice shiny new S3 after being over on the dark side with my iPhone (I know I know!!!). However, I do love one of the things I can do with my iPhone which is listen to my music in the car via the port at the bottom by using a Y cable which splits the output into a USB plug (for charging) and a 3.5mm Jack for AUX in sound.
Does the S3 offer music output and charging via the micro USB slot at the bottom? Has anyone tried this? I've done numerous search's and keep coming up short, with the exception of a post on here that shows the amendment of an iPhone Y cable into a Micro USB version, but that was for the S2.

If your interested in a car dock the Samsung infuse dock works for a single dock connection, but of course the dock has a charger and audio lead.

Hmm, worth thinking about! It's the all in one solution I'm after, so this might work.
Any idea if Samsung are going to bring an official dock for the s3?

The microusb does support outputting audio+taking in power.
I haven't seen a cheap cable for that purpose but just made one myself in the end from an old usb cable, an audio cable and a 690K resistor.
A y-cable made for the S2 should work fine on the S3 (that is what I based my cable on)
Ebay will probably have something suitable

Thanks for that, any write up on how it's done? What's the sound quality like please?

[Q] 11 Pin MHL + USB OTG

Hey folks, im crossposting this, as i believe it didnt get the attention it'd have had i posted this in the accessories forum in the first place

Hey there, i have tried gathering information about this subject and it seems all threads always lead to this announcement:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
Short: Samsung have changed to an 11 Pin-out to enable USB OTG and MHL Hdmi out at the same time. I purchased an original HDTV Adapter (EPL-3FHUBEGSTD) which as far as i can reliably count indeed has about 11 connectors inside the USB connector that goes into the phone.
Now, i can get HDMI out just fine, but ONLY when i also connect the MHL adapter to a power source (a PC USB Port will do fine), however i have also read, that the phone is able to power the MHL adapter itself but obviously would not be charged then (no surprises there). This does not work however.
Further, connecting a USB OTG cable to the micro usb port on the MHL adapter does nothing. No notification and no devices connecting. No power either, since the LED on my USB Hub does not light up as it should. Connecting any devices to the hub does nothing to change that situation. If i leave out the MHL adapter and connect the USB OTG cable directly to the phone, everything works perfectly. I have tried this with 2 different OTG cables so they are not the problem.
This is an original genuine HDTV Adapter for our phones, which according to that post should be working fine with USB OTG.
AFAIK, this topic --does-- come up more frequently now as i can find a few more discussions about it, albeit none really helpful:

http://forum.xda-developers.com/showthread.php?t=1811435
That wiki entry is the most interesting link as it definitely states that using MHL and USB OTG simultaneously is possible and is also the reason why the 5 pin layout was changed to an 11 Pin layout.
Looking forward to reading your replies!

I don't see why you would feel the need to ridicule me for bringing up this thread. it's not wishful thinking, seeing as even the wikipedia entry on MHL clearly states it should be possible. There is also a blog entry on the exact same topic and even the movement to boycott samsung accessories have stopped because of this: http://www.galaxymhl.com/
I don't really understand why people aren't looking into this more.

I'm not ridiculing you. I want the same thing. What I said was my legitimate wish list. I haven't bought the mhl adapter because I'm holding out for an all in one solution. I'm still waiting on Samsung to give us a product that does mhl and otg simultaneously.

I'm sorry, i must have gotten that wrong. I find it very confusing Samsung do no release enough information on this in order to make it work. Neither the phone documentation, nor the official 11-Pin HDTV Adapter manual mention this in any way.

I'm waiting also for a dock with MHL+USB OTG at the same time by Samsung, I dont understand why the official MHL adapter does not support this already but I've been searching and I have not found yet any example of both working together. It clearly seems that the MHL 11 pins cable we can buy right now does not support this since nobody has tested it succesfully but what I don't know is if that is related to Hardware or it also has something to do with software. I read a couple of weeks ago that Google was thinking about using the phone as a PC via docking, I think the idea comes from Motorola? So maybe the availability of both connections at the same time is also related with android, who knows, maybe in JB it will be possible...Has somebody tested MHL+USB OTG in JB with the official adapter?

As soon as i get home, i will try flashing this rom: http://forum.xda-developers.com/showthread.php?t=1695562
It comes with the latest stock kernel and appearently won't boot with anything else so Samsung must have made some changes to it. In a few hours time I'll be back with information on how that worked out.

I can confirm it NOT working on Jelly Bean. The MHL adapter does provide video HDMI output, but only as long as it is plugged into an external power source. When connecting an OTG usb cable, there is no reaction at all. There has to be some way of getting the phone to power the HDMI adapter. Do any of you folks have a good link to a kernel dev who can have a look into this? There has to be a MHL modul for the USB driver. Ghokanmoral probably has more insight into this...
Summary: USB OTG and MHL work fine separately, but not simultanously on JB using a standard genuine Samsung EPL-3FHUBEGSTD adaptor.

The final result of this is that USB OTG work with the Samsung dock, but not otherwise...and that is why they changed the pins to 11. For the dock to allow for OTG at the same time as HDMI out. Does everyone agree?

I don't really know how this is accomplished with the dock, but if it works with the dock, I have to think that the same technique could be used to make it work with other adapters, too. If it's a matter of putting a voltage or a resistance across two pins, that would not be a big deal to do.

It was figured out in the thread that this was split off of.
we already found the resistor value to do it, the wiring.. everything.

Anyone try...
Anyone try a usb Y cable which will inject power over a USB and still allow for a separate device to be attached? I would post a link but i'm noob here. You can find it as "UTStarcom USB Adapter Y Cable"

The HDMI part of the split HAS to be powered...but the USB OTG does not. So...if there was such thing as an 11 pin micro usb Y splitter, then the OTG side would work while the powered MHL adapter was on. Essentially this is what the dock does.
Is it possible to create an 11 pin Y splitter? Someone needs to get one of those docks and tear it apart to see how the leads are split...lol

[Q] Motorola Lapdock & Note 2?

Just curious if anyone has gotten the keyboard and mouse working on a lapdock with the Note 2. The HDMI works perfectly, but the keyboard and mouse don't work. I don't know if it is possible, but it would be great if someone knows how to make this happen.
Here's a picture of my set up. Everything is connected so it *should* work. I'm thinking that it is a driver issue.
(The lapdock keyboard & mouse work great with Ubuntu 12.04, & Windows 7, & Raspberry Pi (Raspian), so I know that my connections are fine.)
Thanks!

Hmm, guess I'll be able to answer my own question after a bit of research. It seems that the Note 2 (like the S3) can't provide MHL & OTG at the same time.
Not sure if there is a way around this. I wonder if Samsung's SmartDock works, but I don't want to spend $100 to find out.

I'm increasingly interested in trying just this, smart dock + lapdock. Hard to imagine that it wouldn't work, but I wouldn't mind confirmation if anyone has tried it. The impressive low prices on lapdocks in the secondary market kinda offsets (and also kinda shames) the ridiculously overpriced smart dock.
I wonder if the lapdock's battery can provide as much power as the smart dock needs or if I'd have to have an external battery too.

the lap dock should provide 1 amp which is what the atrix needed and the chargers it came with. the s3 has a smart dock and it too only has 1 amp chargers...
plus I don't see the smart dock pulling more than 200mA it has to provide the s3 with at least 750 mA for the charge to survive mhl.
regardless amp drain in android devices is adaptive. even if the dock needs a full 800mA the phone will try to survive with the rest draining battery of course but working none the less just like trying to charge our 2A monster with a Bluetooth 150mA charger. it will try but at best slow down the discharge

I don't know if an MHL adapter will supply both HDMI and OTG at the same time but I know the phone is capable of it because this is how the Samsung Smart Doc works. 3 USB ports with HDMI out.

I got it working. I have a Raspberry Pi that connects to the lapdock perfectly so I picked up the overpriced Samsung SmartDock and used the same cords that I'm using with the Raspberry Pi and it works pretty well.

Hi I have got an S3 MHL(11pin) HDMI cable. I have tested HDMI & OTG simultaneously.
http://forum.xda-developers.com/showthread.php?t=1953061&page=7
It is working perfectly with my 24inch LED monitor and a USB hub containing 2 pen drives and one wireless keyboard & mouse
Now the next move i got atrix lapdock and try to connect the HDMI out from mobile to Lapdock (with necessary adopters) but i am getting only green screen.
Lapdock is working with other HDMI sources....
Any idea on how to get my note 2 HDMI working in my lapdock?...

I've never gotten a green screen so I have no idea. And, you already did the basic troubleshooting. Are you using the Smartdock or something different? If you aren't using the Smartdock, maybe pick one up to see if it works. If it doesn't fix the problem, you can always return the Smartdock.

Based on what you are saying, it sounds like the issue is between your lapdock & MHL cable. Like I said in my previous post, I'd pick up a Samsung SmartDock and see if it works. Just make sure that yo buy from somewhere that you can easily return it in case it doesn't work.

Dear wilbr,
Thanks for the reply.
Do you use the original samsung MHL cable?...
I am using Chinese version of MHL.
HDMI troubleshooting guide says the below....
The green screen problem could be due to HDCP non compliance or syncing problem..
anything to do with HDCP and chinese cable?...
I am trying to get an samsung official MHL or a smart dock to try out. (here in india smart dock is still not avaiable). My once route to get it is through china...

I use the Samsung SmartDock. I was able to get the Lapdock to show the Note 2's screen when connected via HDMI with a Chinese MHL, but I couldn't get the keyboard/trackpad to work with it.

hi team,

my lapdock is AT&T atrix 4g model... anything to do with it?.....
I have tested my set top box,LAPTOP and Notion ink adam..all are working but not with my note 2.

Hi refer my link posted in my earlier reply... it is easy to get the OTG simultaneously with HDMI....
For me i have connected both HDMI and USB together with lap dock.
MY lapdock keyboard and mouse are working fine and i can see it with note 2 screen....
USB port is working fine with 2 pendrives attached......
The only problem is not able to get the screen in lap dock ....only green screen...

update....
Tried with S4. HDMI detected but blank screen.
When playing video once cable is connected S4 screen goes blank but still video is running but lapdock is blank....

Team,
I have updated Android 4.3 + rooted hoping that it should work with lapdock... Still no luck.. still getting green screen.
Any help or update?.
wilbr,
Whats your android version?
Is it rooted or stock rom?...

If you are using Aosp, mhl doesn't work with Aosp.

I cant post a link to it so you'll have to Google it sorry

Hmm, guess I'll be able to answer my own question after a bit of research. It seems that the Note 2 (like the S3) can't provide MHL & OTG at the same time.
Not sure if there is a way around this. I wonder if Samsung's SmartDock works, but I don't want to spend $100 to find out.

I've already got a Bluetooth keyboard and mouse. I'm gonna order a MicroUSB to HDMI adapter and go that route. It'll be cheaper and less to carry. When I travel I'll just be able to plug into the hotel TV and go wild!
There's a YouTube video of someone demonstrating it, just search YouTube for "Samsung Note 2 Mobile Desktop with a Bluetooth keyboard mouse"

i had a similar problem, its was a shotty solder job on the "Budget adapter" (HDMI PINS). i took it apart and cleaned it, works perfectly now.
Plug your phone in, WAIT 5 SECONDS, Then lift up.....If you still have a problem, push F11 on the Lapdock... that manual cycles the resolution modes...at least thats what the manual says....
As far as the USB key board goes, im currently working a solution.... you have to power the MHL THROUGH THE DOCKS usb port using a donated USB cable with the end cut, solder it in directly on the board of the adapter itself, then make a micro usb extension that has the power wires cut and D- D+ reversed... I have a motorola ATRIX and im looking at the board, it looks like they have been reversed....ill post up some pics if i find this to be true.

Also, sorry to bring up and old post, but I have a reason to believe that the ZOOM bluetooth keyboard uses the same 30 pin connector thats inside the lapdock (connects everything together) all the connectors are the same, except on the ZOOM the other end is a BLUETOOTH module...this would solve the whole issue... im about to get one on ebay. Ill report back in a few days.
I WILL NOT LET THIS THING BEAT ME
