Got a quick question for those of you with the HD dock. Are you running dual USB devices for you mouse and keyboard, do wireless usb devices work for the dock sans drivers, or has anyone found a way to pair dual devices to have a bluetooth mouse and keyboard functional?
My dilemma is where I am planning on putting my dock, it's going to be really difficult to use wired devices because the dock is going to be located physically behind me. I need to find a way to go as wireless as possible so but at the store we were only able to pair up one bluetooth device at a time. Has anyone found a work around for that?

I've tried a couple of wireless keyboard/mouse combos plugged into the dock and neither worked. I'm currently using a powered usb hub plugged into the dock with a Logitec keyboard and mouse plugged into the hub. Works great.

Damn... That's what I was afraid of. My issue is I'm placing the dock on my nightstand located next to my bed for charging purposes. What's throwing me off is in one of the videos demoing the dock it shows them using both a wireless keyboard and mouse. It's gotta be possible, but I have no clue how. At the store we couldn't pair up two seperate bluetooth devices at the same time.
May have found a solution to my problem. At a local Compusa I found a bluetooth keyboard and trackpad in one. I'll take it to work and test it out... If it works, I'll report back.
My Logitech Wireless Desktop (USB Unifying receiver) worked fine, out of the box - keyboard and mouse.
There shouldnt be any reason that your generic wireless device/receiver combos dont work since they're simply a transmitter/receiver pair, your problem is likely with the lack of adequate power supplied by the dock. Theres no way that power supply puts out enough to power the phone as well as the USB ports so thats probably why the powered USB hub mentioned above solves everything.
hey.
i have sailed the internetz looking for answers for this. but i thought ild ask what everyone else thought.
would atrix lapdock work with sg2? (with mods off course) like changing the connectors about. and using a mhl to hdmi cable?
i was looking at the connectors and it is a micro hdmi and a micro usb if im not wrong..
whats everyones thoughts to this???

NO.
Atrix has two different output ports. Micro USB for charging and data transfer, and micro-HDMI for TV-out. The laptop dock specific (I stress specific) for the Atrix uses BOTH of these ports in conjuction.
Galaxy S2 has ONE output port, a micro USB port that doubles for charging/data transfer, and connection to the optional MHL adapter accessory.
In NO WAY would you be able to MacGyver the Galaxy S2 to use the Atrix laptop dock.

You know... it just might work. The atrix lapdock does feed 5v power up the usb port which you could adapt from micro usb to whichever varient you need on your MHL cable. This would provide the power necessary to drive the hdmi circuitry that you had feeding into the micro hdmi input of the lapdock. Obviously you wouldnt have a true 'dock' but it sounds like you understand that. As long as your phone detected the mouse and keyboard as input devices it should work. Not sure how that operates with an MHL cable. It might require USB OTG, and im not sure if that is available over the USB connectivity provided by MHL. You could try with a standard usb keyboard If that works, then the lapdocks should too.
I know for certain that you can use the lapdock as the screen by just connecting the video out of the MHL adapter to the lapdock, and a usb power only cable (for the MHL adapter) to the lapdocks normal USB charge ports.

ive seen some mhl cables online which have a micro usb port on the side also. so you can plug in the micro hdmi and usb at the same time .. not as the other guy said. anyway im going to order the dock to see what mods i can get done. if anything promising il repost.

That thread is from the Atrix forum. What bearing does that have on the argument on getting this working on an S2??
Have you even looked at the connections involved here?
The Atrix's micro USB and micro HDMI port are side by side, and the dock plugs into both of them.
The MHL cable plugs into the ONLY port on the S2.
So I'm certainly not an expert on the inner workings of MHL, USB, and HDMI, but from what I can gather, you would have to splice an MHL cable to separate out the USB leads from the HDMI leads, then try to run the HDMI leads into a micro HDMI female port, and run the USB leads to a female micro USB port. I don't even know if that would work with MHL in the equation. I'm fairly certain the phone detects what is plugged in and decides how to use the port, which shoots this down idea down altogether... unless more hacking is involved into the OS. Which is way above my head, and I'm not fool enough to try.
See this thread, which is admittedly for the Galaxy Nexus, but is WAY more relevant than the Atrix thread you linked, as the GNex is also manufactured by Samsung, and also uses MHL technology.

No - the micro USB port on the side of the MHL adapter is for power. If the HDMI port you plug into is NOT MHL compliant (and not many are, yet), you need to plug an AC adapter in to power the phone while HDMI is in use.

well. theres allot of different mhl cables. even if none of them support it. splitting the usb data from the other cables on the mhl should be easy. but like i said il order one to play with. im pretty sure even if i cant do anything with the sg2 il find another use for it. would be great for a project. but many thanks for your input. sure has shed some light in the dark.

Sure, there are a lot of MHL cables, but they are all essentially third party versions of the OEM Samsung MHL cable. (or whatever phone manufacturer you have that uses MHL - HTC, whatever)
I have high doubts ANY MHL cable will support it, since as I said, the phone will detect what type of connection is attached to decide how to send/receive signals from the port - if it sees the MHL adapter, it will do charge/HDMI; if it sees a regular USB cable, it will do charge/data transfer/OTG; if it sees an AC adapter, it does strictly charging. Notice how it can tell the difference when you have it plugged into your computer as opposed to when you have it plugged into the wall?
But if you want to go for it, good luck.
EDIT: yet another piece of info shooting this idea down.

i pretty much thought the usb and hdmi wouldnt work from the beginning, il have to look into modding the dock to allow bluetooth. ive have just looked at the specifications of a mhl even though they can in theory support usb and hdmi at the same time. the sg2 wont. and i cant see any software mod that would allow this. il see what sort of bluetooth mods are available. maybe incorporate stuff i have done in the past. but the dock is too good to pass by.
i think we can close this thread as its been answered.

Not to nitpick, but it's MHL 1.0 that won't support it. The GS2 just uses MHL. Who knows if there's a possibility to update it to whatever MHL 2.0 is, whenever it comes out.

Could this phone potentially be able to charge, be HDMI out and be connected to a keyboard and mouse all at the same time? Or can you only do some of these features? I Saw the video of the phone being connected to multiple devices but how about everything all at once?

It cannot be connected to MHL and USB OTG at the same time, but you can do everything you mention with an MHL adapter (which has, and requires, a charging input in order to be able to use it), and a bluetooth keyboard and mouse.

So you're telling me that it can only do Video out or read/write to USB devices but can't do both at the same time?
The reason I ask is because I'm thinking of designing a board with its own power source so that it only requires to read information from the 11 pins to accomplish everything.
I want to charge the phone, have a few USB ports and a HDMI port and have the phone interact with all. I just don't know the specs of the board or what is going on. Maybe I need to get in touch with superico.
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://android.stackexchange.com/qu...-of-11-pin-mhl-connector-in-samsung-galaxy-s3
http://forum.xda-developers.com/showthread.php?t=1743128

http://en.wikipedia.org/wiki/Mobile_High-Definition_Link#11-pin_MHL-USB_Connector
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!
the ability to use MHL and OTG simultaneously would give the S3 so much more purpose. It is powerful enough to replace a desktop computer used only for light stuff like browsing and watching videos, and even simple gaming. If samsung made a dock like the one for the motorola atrix I'm convinced they will broaden their target group. The atrix got everything right with this but is inferior hardware wise. I love the idea of a one device for everything concept. Unfortunately it doesn't rhyme very well with the growth society.
Love the MHL and the OTG is even better only after I got the correct cables as the cables changed on S3 to the S2 version, unlimited space for watching films on my phone is now awesome and even better connecting it to to the TV just need a good dock,
is there perhaps any expert advise on this? According to multiple sources it should work but really doesnt. Did i buy the wrong mhl adapter?
I think they will only both work together when being used with an MHL enabled tv. That way the power comes from the tv and the usb on the adapter can be used for the usb-otg cable.

But if i connected the MHL with the s3. Would sound come out of my phone AND my TV or just my TV. If it justs comes out of my TV, then can i hook up my bluetooth headphones and listen to my video or it would not allow me?

Ah ok sorry! Afaik you should be able to choose your headphones as primary audio source in the bluetooth settings. I know I can choose what I want to be output to my bluetooth headset, but I don't own an MHL adapter so I don't know about that. Someone with one should be able to try it, and if they don't own a bluetooth headset/pair of headphones they could try with wired ones and see what happens.

I have recently received an MHL connector (5 pin type) and the samsung 11 to 5 pin adapter for it. I can confirm that if I plug my OTG cable into it, and then into my powered USB hub, I can get the MHL to work just fine, both video and audio. The OTG cable powers it just fine, but does NOT allow me to use other devices attached to the USB hub.
I am still researching. I suspect you need to bring all 11 pins off the phone with a splitter of some sort, or possibly wire data lines through the MHL. Probably not with the 5 pin MHL connector and 11 to 5 pin adapter, but with the full 11 pin MHL adapter. I am not up to that level of hardware hacking. I suspect whoever does it first can sell a BUNCH of them!
Oh, and I have a Moto Lapdock for my Raspberry Pi, and would love to hook my S3 to it too!
