Galaxy S III MHL Adapter Supports USB OTG--Work with GN? - Samsung Galaxy Nexus

The new MHL adapter for the Galaxy S III supports both HDMI and USB OTG simultaneously, according to this article:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
I'm wondering if this means it could be used for USB OTG with a flash drive while charging the phone at the same time--something that's impossible with current adapters and cables. And does it also work with the Galaxy Nexus? Does anyone happen to have the adapter and a GN to test this?

My friend has an S3 and I know the 5 pin MHL adapter we use doesn't work with his because of the pin configuration, so I would assume if he can't get HDMI out using the 5pin, we won't be able to get HDMI out using the 11pin. Of course I am only guessing, but it makes sense to my mind.

I don't see how it could work, to use the HDMI out you need the charger cable plugged in to the MHL adaptor. So where would the OTG cable go?

Looks to me like the standard S3 MHL adapter has a micro USB "charging port". Could be that it could also accept an external drive. I don't have the phone or the cable yet, so I can't test. Maybe somebody who has both could post results?

it's not actually a charging port, it's a power port because apparently it needs more power to output HDMI, i.e. if you don't have the charger plugged in to the vacant port, no HDMI.

Samsung does sell a bunch of dual head micro usb to usb cables.... so maybe you need one of those and they sell this: http://www.samsung.com/us/mobile/cell-phones-accessories/ET-R205UBEGSTA which says it allows you connect drives, keyboards, etc to S3's....

Yeah those work, I actually use this one:
http://www.ebay.com/itm/Micro-USB-2...100-Note-i9220-Nexus-i9250-XOOM-/120894431890
or something similar, but you still can't use HDMI when you use those
you can however plug in keyboard, mouse, usb drive and anything else you want all at once which is cool

USB OTG on the Glide ?

Just that, if anybody can try this out would, it would be awesome. You can follow the steps in this article:
http://www.xda-developers.com/android/determine-your-phones-usb-host-capabilities-with-usb-host-diagnostics/
I will make the test myself when I have the phone, but, I live in Argentina so, It'll take a while, I'll be making the payment trough PayPal probably next Monday, soo, that'll be 5 days for the package to be delivered to my courrier's office in Miami, next, another 3 business days for it to be delivered to my partner's house in Chile, and, with luck, another 2 or 3 days till my partner pick it up and bring it to Argentina for me XD
I f*cking hate customs !!! You damn bastards !!!

Thanks ! Sounds good to me, Device detected it's gonna be always no, if nothing it's plugged, so that's OK, and, if the Kernel claims support, I'm pretty sure it'll work, after all, this is "Kind" of a Galaxy SII device.
Are you saying that if this works we will be able to plug in a USB Key or an SDCARD via a dongle and upload files to and from our phone. Wow that would be crazy useful. Imagine plugging your friends android phone in USB mode and transferring some files to him.
If we have USB Host anybody thought about this:
http://www.ubuntu.com/devices/android
Seems like we match all the Requirements:
Hardware requirements
Dual-core 1GHz CPU
Video acceleration: shared kernel driver with associated X driver; Open GL, ES/EGL
Storage: 2GB for OS disk image
HDMI: video out with secondary frame buffer device
USB host mode
512 MB RAM

This is exactly what made me open this thread XD
I have the OTG cable and it works great. I've tested it with a Flash Drive, Mouse, Keyboard, even showed a co-worker how I could charge his iPhone with my phone. Haha
I did the test for you and attached a screenshot of the results.
Wow! That is cool, how did the mouse work? Do you see a mouse in android? Did the keyboard work well? With the flash drive you get to see the files on it?

Yes, a mouse is displayed on the screen. It works great, right click acts like the back button, scroll click like the menu button, left click acts like your finger touching the screen (including drag, click and hold). The keyboard is similar with certain keys acting like the android buttons. Also, you can view and transfer files to and from your flash drive.
It works just like it does on the SGS2, tons of videos on YouTube. It's an awesome feature!
gtdRR, thanks a lot, now I want my Glide more badly than before XD
Somebody could PM the admins so this appears in the News Page.

Wow I can't wait to try this.....Now, how would I use an MHL cable and a USB mouse and Keyboard.... Kind of would turn my phone into a PC if I could do that. Lets see a Micro USB to USB Hub. Plug into the hub the Peripherals then plug the MHL to a Micro USB to USB converter and away I go....Of course power the MHL. I don't think the MHL connector would like to go behind a USB hub though. In theory is this not what the docking station is doing in order to run the Ubuntu on android? OK not with this phone but on the one that they are demoing it on.

It's a lot simpler than that, just use this MHL cable:
http://www.samsungcaptivateglideaccessories.com/capigpitalsdfkzlig-11.html
Just plug it to your phone MicroUSB port, then plug a MiniHDMI Cable to the MiniHDMI port of the MHL cable, then plug that MiniHDMI cable to your Monitor/TV, on the other side, plug your phone's MicroUSB cable into the Female MicroUSB port of the MHL cable, and then plug that USB cable to a Hub, then just plug every other peripheral into the Hub, and of curse, if you're going to use an External Drive or something like that, remember to buy a 9V/12V AC Adapter for the USB Hub.

So your saying to plug the MHL adapter to the phone and to plug the Hub to the MHL device. I do not know if this will work as you need to Power the MHL adapter. Are you saying that powering the hub will power the hub and the MHL adapter? Have you tried this? I have the MHL adapter and I love the HDMI ability of my phone but I found I can not use to long a HDMI cable as it will not work since the HDMI cable is drawing power from the MHL adapter. 3 Feet works and 10 feet does not. I have not tested others in between yet. Oh and yes I do power the MHL adapter via another device (USB port to Power, or a Battery device to MicroUSB)

I have tried using the MHL and USB OTG cables at the same time and had no luck. Didn't attempt with any powered USB hubs.
What I have done is use the MHL adapter, and a bluetooth mouse and keyboard at the same time. Similar to video here, http://www.youtube.com/watch?v=uEb-DICYCgg.

I bought a generic MHL cable online and couldn't get it to work; but got it working with two other phones. So apparently you do have to buy the special Captivate Glide cable. Can anyone verify this? I'd hate to pay extra for another cable that didn't work
What did you have to do to get your MHL Cable to work?
It does look like there are several different ones, so I'll try ordering another one...

He is talking about OTG Cable, not MHL Cable, no one has confirm that the MHL Cable works with the Glide, only way to know for sure, it's buying an Original Captivate Glide MHL Cable, that most likely it's the same one that for all the Galaxy S II variants out there

I bought my MHL cable at Monoprice.com for cheap and it works great with a 3Foot HDMI cable and powering the MHL connector.
THe only reason we are talking about the MHL and USB cable is because you need both working to really use the phone on a screen with a USB mouse and keyboard. I ordered a cheap USB host to Microsub cable on ebay when it comes from China I will let you know if it works with and without the MHL.

Did they work together?
Works for me sort of...
My micro usb port is loose & i have to hold the phone & cable tightly together to get it to connect. Because of this i can no longer charge my phone directly & have to charge spare batteries separately & swap when they run down.
I can also confirm the hdmi out works too & i have a bluetooth mouse that connects nicely at the same time for remote control.
Wished they would have used a usb mini instead of micro, as the micros tend to fail after moderate use.

Has anyone attached two USB devices?

I want to attach two usb devices to my Note.
One will be the MHL adapter and one will be the 2.4ghz wireless unit for a keyboard like this http://www.ebay.co.uk/itm/250996855143.
I need a Micro USB male to 1x Micro USB female and 1x USB female adapter.
These for some strange reason don't exist
I was just wondering if anyone has done anything similar.
I know I could get a Bluetooth keyboard, but I don't have one. I do however have the above keyboard
Oh wow! I'm interested into this keyboard! Does Lenovo Mini Wireless keyboard work perfectly with the Note? All buttons are recognized and trackball mouse is usable?
Its really good, i use it on my Note and my Libretto W100. The mouse and keyboard work perfectly.

You cannot attach 2 or more devices to the same usb port. You need an usb hub for that, but I don't know if the MHL would work with the hub. I will try later today to attach an usb hub and connect more devices, and will report my findings.

Edit:
--------------------------------------------
I have successfully connected a self powered usb hub to the galaxy Note, and connected 2 thumb drives, a combo card reader, and a mouse. The Note mounted both of my thumb drives, as /usbstorage/sda and /usbstorage/sdb respectively. Then I inserted a mikroSD card into the card reader and the phone mounted it as sdc. I then inserted an sony memory stick into the card reader and it was mounted as sdd. All mounts were usable, and I could watch movies from them, and watch pictures, copy files from one to the other, etc... But, when I connected the mouse to the usb hub it didn't recognize it. Whatever combination I tried the Note would not recognize my mouse, when plugged into the usb hub. When plugged directly to the OTG cable it works perfectly, but won't work when connected to the hub (maybe cables are to long).
Using rooted stock xxla6 firmware.
Edit2:
---------------------------------------
Just found out, that usb otg and mhl cannot work simultaneously. When the MHL cable is plugged in, the GNote's microusb port will become an MHL port, and from that point it will not act as an usb host or usb slave. :-(
It's too bad, 'cause I really wanted to connect it to my full hd monitor and use a mouse and keyboard, too.

How about bluetooth mouse+keyboard instead ? That would keep your USB port free for MHL

This is the setup I'm going to do also. But as with topic, it's also very tempting to have everything USB powered. Since it will decrease latency and maybe power consumption as well? (as opposed to bluetooth) Well, MHL to HDMI will still drain our battery even if we connect it to power source

MHL with USB OTG?

Has anyone found a MHL cable that also includes a USB OTG port? Samsung reportedly changed from a 5-pin configuration to an 11-pin configuration to allow MHL with USB Host mode simultaneously. Perhaps for a future Desktop Mode?
Has anyone been able to find one of these cables?
Just wanted to update, I believe I found the type of connector that I was looking for, but it is missing HDMI and it is sold out. This essentially could give you PC type connectivity on the S3.
http://www.mobilefun.com/35462-mobile-fun-connection-kit-for-samsung-galaxy-s3.htm
I think we still have a bit of a wait. What you found is essentially a USB OTG hub with some card readers built in. I seriously doubt this will pass through the pins for HDMI to work out of the usb port. We'll see something when this phone finally launches everywhere. It's not even out in the US officially yet
EDIT: Sorry, didn't see the article in the link in the OP. Man.. I might have to get me a GS3 now. I'm quite satisfied with the reasoning for a pin change. =)
Samsung sells 11 pin MHL adapters and USB female to Micro USB male adapters on their accessories page, but I'm not sure if you could piggy back the USB input into the charging port of the MHL cable. I don't see any all in one cables on their site, and the desktop dock is just micro usb/audio. I tried.. =(
Here's what I was looking at.
Old and mostly unrelated. See edit.
I happened to buy what looks exactly like that adapter today earlier at Micro Center. Now, I do have a Galaxy Nexus, but the USB OTG works great with keyboards/usb/mice/hubs; however, I cannot get it to simultaneously work with my MHL adapter. I understand the GS3 has a different pin layout though for MHL - my phone works with my MHL adapter correctly, but I didn't think it would have any change on the USB OTG. I'll most likely be breaking these apart and start tinkering. My goal is to show people how much of a full desktop-like experience I can provide from my phone, since so many people somehow think a GNex or GS3 are inferior to tablets, just because they're smaller... lol
Good luck finding information out on some kind of MHL/USB OTG setup. I'm just trying to provide any information I can from how my situation works with MHL/OTG, since I'm currently on the quest to achieve this myself.

I'm not really sure why people think they NEED MHL and USB OTG simultaneously to get a "desktop-like experience". You can already accomplish this with just a plain MHL cable and a bluetooth keyboard and mouse as was demonstrated in the Connectivity Demo video on youtube.
Edit: Actually I just remembered about portable hard drives. If you want to hook up a mouse, keyboard AND hard drive I wonder if you can plug all three into a powered USB hub connected to a bluetooth dongle. Hmm...
I'm looking for a dock with USB OTG, charging and MHL. Maybe some day.
I believe this is already capable. Everything I say here is purely speculative, but what I see is that Samsung moved to a 11-pin connector for MHL and the standard 5-pin is no longer functioning. To call it MHL, they probably have to use the same standards for data encoding... but they simply "moved" the pins.
I put "moved" in quotes because of the way in which a standard 4 pin USB cable works (or 5 pin for our case)... you have a +5V, Ground, Data + and Data - (one data to phone, one data from phone, carrying ALL data). Since our phones still sync via 5-pin cables, this means the 5 pins are still "hot" for data like all other phones. I am presuming, that for the 11-pin connector, Samsung simply added a few more data+ and data- connectors (much like having two or three USB ports on a normal computer) but consolidated the ground/5V reference. I could be wrong, but it would make sense.
Lets call the stock 5 pin data connectors (2 wires) USB1. This is where MHL is conventionally sent through and all sycing can be completed through, 5 pin cable or 11 pin cable. If samsung added two additional USB ports to the single connector, lets say MHL is now over USB2 (wires inaccessible to 5 pin connectors). This frees up bandwidth and COM ports on USB1 and USB3 to use for accessories like a USB hard drive and keyboard/mouse. On a 5 pin connector, however, only USB1 is accessible. The Samsung 11pin to 5pin MHL adapter simply moves the data+/- from USB2 to USB1 (standard 5 pin location), so with the adapter you are syncing/exporting video over USB2 on the phone with a standard 5pin cable.
My thinking is such: If you plug in the OEM 11pin MHL adapter, it will also have access to the standard 5pin USB1 connection. Since USB2 is used for MHL, you can then plug any OTG device into the micro USB connector on the MHL adapter to make use of it. The only problem here is power (or lack thereof). By plugging in a USB hub with a discrete power source, plugging this into the MHL adapter, and plugging in the USB device of choice into the HUB, you *SHOULD* be able to get simultaneous data and HDMI. This assumes they put the standard 5 pins to the connector on the side of the MHL adapter and only wired the HDMI to the USB2 area.
Alternatively, you *SHOULD* be able to plug the micro USB cable from the MHL adapter into a computer, and simultaneously be able to sync files while outputting HDMI video. It sort of just comes down to being able to provide power to the MHL adapter on the +5V pin while using the data pins to access the phone. As soon as I have my MHL I'll figure it out, but that could be a bit. If anybody has access to a pinout from a Samsung 11 pin micro USB that would be helpful too.
Again, just dreaming here. I don't know anything about this, but if I was the engineer at Samsung I would choose this over analog outputs like Apple used for their giant connector.

for me at least i already have several keyboards and mice ... none are bluetooth.
I'm looking for the cheapest option available.
I'm just hoping someone releases a cable with 4 plugs:
Male MHL - To Phone Obviously
Female MicroUSB: To plug in charger
Female HDMI - To Display
Female USB - To USB Device
That's all I want... should cost less than $2 to make, just sell it for $20 and I'd be happy.

As soon as I have my MHL I'll figure it out, but that could be a bit. If anybody has access to a pinout from a Samsung 11 pin micro USB that would be helpful too.
Again, just dreaming here. I don't know anything about this, but if I was the engineer at Samsung I would choose this over analog outputs like Apple used for their giant connector.

hi v8bait, are you able to get data thru the micro usb port at the side of the 11-pin mhl adapter? i was thinking of using the motorola lapdock with my s3 thru the mhl adaptor (other then a micro hdmi male connector, the lapdock also has a micro usb male connector that apparently send out power as well as push keyboard/trackpad data upstream) - if it works, we can have an inexpensive "clambook"
Just to recap,
Will this we possible:
Official MHL adapter -> hdmi to monitor.
|
>OTG cable> Powered USB hub> USB keyboard & mouse.
In other words, the PC Experience with a keyboard and mouse.
Dont really want to spend the money to buy a Bluetooth keyboard and mouse when the USB ones can work just fine (theoretically).

I am also very interested in this exact thing. Using USB devices (multiple ones, e.g. plugging a powered USB hub into S III and then plugging them in) but also putting out S III video to HDMI.
However the other workaround is using AllShare Cast. In fact that is the route I'll likely go, because of the other unique advantages of AllShare Cast (i.e. using it for presentations to screens, etc.)
So: has anyone plugged a powered USB hub into S III and used multiple devices? Such as a keyboard and mouse?
I also want to use this S III more as a computer. the other perfect thing I wish I could buy would be a keyboard case, like the one available for iphone, so I can prop the S III up on a kickstand and use a real mini-QWERTY physical keyboard.

We're in the same boat; i want to use the s3 like a mini computer too. I think it'd be great for business travel, when i dont really need a laptop during the day but want something when i'm back in hotel room. I'd much rather use hotel TV instead of a laptop because that's what i am used to at home... pc hooked to TV.
I've been planning to use the allshare cast dongle too, but they dont seem to be available yet. I was thinking HDMI out with the allshare.. charging with the wireless charging kit and then keyboard and mouse with USB OTG. My logitech unifying receiver for keyboard/mouse works perfectly i just need the wireless charging and allshare dongle to be released.
For what it's worth I tried a powered USB hub and could not get it to work with the s3.

Wait so your saying you tried a (a) powered USB hub with a OTG cable connected to the phone or you tried a (b) powered USB hub connected with a OTG cable to the MHL adapter and then to the phone?
If it was (a) then there are some vids out there of ppl using powered USB hubs.

So has anyone received their Official MHL adapater and tried USB OTG?
Very interested in this.,,
I'm puzzled that there aren't any more postings about this kind of stuff. I was expecting the GS3 to be easy to use as a "PC" replacement but it seems no one besides us few wanted to do that ? A simple cable should have done it but I'd even be willing to shell out 40-50$ for a decent dock that would do just that

Me too.
But it is possible to get that this way working:
Code:
S3 -> Mobile Fun Connection Kit -> microusb -> HDTV Adapter TIP (5 to 11 Pin Converter) -> MHL HDMI adapter
|
-> USB -> keyboard etc.

Maybe I'm not reading these posts correctly but I am using an usb keyboard and a usb mouse on my S3 with no problems using these two accessories:

http://www.amazon.com/Micro-USB-OTG...UTF8&qid=1343846045&sr=1-3&keywords=otg+cable
Have my keyboard and mouse plugged into the usb hub and then the usb hub into my usb OTG cable which of course plugs into the S3. Everything's working on my end.

I have the official MHL adapter and there is no female USB port on it for OTG

You are not reading it right.
they want to use the MHL adapter, too.
As far as i can tell, the MHL adapter needs to be in the phone, not a hub. it is all dictated (the output being OTG, or MHL) by the impedance of what is plugged in. It is an either or situation.
Perhaps with a firmware update they MIGHT be able to run both signals and split it.. but i doubt it.

MHL and OTG at the same time: Maybe we're going about it wrong?

I've read through most of the postings about the GS3 and MHL/OTG going at the same time. I've been doing a lot of thinking and I'd like to know exactly what those MHL enable samsung TVs do to the HDMI standard that allow it to power the MHL adapter and phone. I've done a lot of power injection on ethernet and it doesn't scare me in the least...
what I'm getting at, I suppose, is that if the HDMI port is supplying the required juice, we can use the official GS3 MHL adapter for OTG and HDMI at the same time correct? if so, can we kludge an hdmi power injector right in front of the adapter, between the HDMI cable and the HDMI port on the MHL adapter? that $60 atrix dock is calling my name, but only if we can get it to work correctly.
I'm not having much luck finding out more about those mhl enabled TVs. Anyone happen to own one that has a multimeter?

Don't forget one thing, has the usb connector usb function, or only power?
If it's the last it still won't work..

as was figured out in another thread:
there multiple things making both not work at the same time:
1. as has been seen so far, none of the MHL adapters connect to the data pins on the usb of the phone (they do not have those 2 pins wired to anything, so no data can pass, they are all using the extra 6 pins for the MHL)
2. the 4th pin in the USB switches between different modes, it needs to be directly connected to ground for OTG, but it need a 1k resistor for MHL.. that means the phone will only switch one on, or the other.
3. the only possibility is: a fully rewired MHL adapter, with a custom resistor value wired in, and a special Kernel or ROM that would turn both on when it sees that special resistor.
we need hardware and software that do not exist for it work.
hi guys. i was able to make usb otg and mhl work together just like smart dock.

MHL Cable working!?

My monitor came with a MHL cable, (Micro USB <-> HDMI)
And my moniotr has a ports that is writed Port1 (HDMI/MHL)
When i plug it on my N7100 do not appears nothing on the Screen, what should i do!?
The mhl cables have to have the double charging and USB port in order for them to work I believe. The cable has to have an adapter that allows you to charge the phone and output media to a specific device. If the mirror option on the note 2 isn't readily available or plug and play, you may also need to install a ROM that has that feature built in.

The mirror option is how you display media from your phone to TV like pics and videos. Google T-Mobile mhl adapter and you will see what I'm talking about. It charges the phone and display the media your trying to play. A mhl cable by itself will not work. You need that adapter
