(Q) can I use MHL HDMI adapter via 30 pin galaxy tab to micro USB adapter

Hi ,
I wanted to use my galaxy s2 MicroUsb HDMI MHL adapter and OTG USB cable with Galaxy tab "7" with this 30 pin galaxy tab to micro USB adapter.
Any help regarding usb host and hdmi capabilities will be appreciated.

HDMI is supported via Samsung Media Dock. Could have googled for that. There is no listed USB OTG support listed for it, but there is a Keyboard for it, which could be indicative of UDB OTG support, at least of a proprietary nature. Both of these accessories require the standard charging cable to provide power during use.

I bought Mhl adapter because i was going to buy galaxy note. Then at the last moment i changed my mind and bought galaxy tab 7 t-mobile. My media dock as also arrived. But still waiting for 30 pin con to mic usb adapter and mini hdmi to hdmi adapter. I will let every body know if any thing is discovered.

As it stands, HDMI is available through the Dock as mentioned, but there is no USB OTG support. Keyboards can be connected to the 30-pin (Samsung keyboard) or through Bluetooth (third-party keyboards).
There was a project to get USB Host support going, but it seems to have stopped. You can try the OTG gear since there are many variants of Tab and many ROMs etc, but I don't think you'll get anywhere with them since the stock software doesn't seem to support anything apart from the Samsung official accessories.

I am working on getting USB OTG working, but it wont happen anytime soon.
You cant just plug in anything that fits and expect it to work. The Galaxy Tab 10.1 30-pin to USB and 30-pin to SD are for that device.

so in conclusion, it never work?
I was thinking of using OTG + USB to RCA cable rather than HDMI...
I am using GT 7.0 plus
see if someone can answer?
is the OTG P1000 USB working on the plus model?
thks!

Split the micro USB for charging and USB OTG

Hello,
I want to do some stuff at the same time with my phone.
Watching a movie from an usb stick while charging the phone.
So, I've bought this HDMI converter
When you plug this into the phone you can plug in your charger or USB OTG adapter in the usb port on the HDMI converter.
But i can't find any splitter cable on the internet or ebay so i can charge my phone and connect my usb stick at the same time.
I wonder if this is even possible. It is possible to charge the phone when HDMI converter is connected and it is also possible to connect my USB stick to the HDMI converter.
Anyone ever tried this or has found a simple micro usb splitter cable or normal usb splitter cable?
You can't connect a normal USB Hub because i can't send power back to my phone through the hub.
Thanks :good:

Sorry I can't help with your splitter request.
However I'd be really interested in knowing if those two items work fine with the Note 2?

so the i know it isnt possible with the 5 pin mhl adapter (the old one thats not compatible with this phone)
I wonder if the 11pn version does allow this. I know the cables dont exist for what you are looking to do, there is a galaxy note smart dock 2 that seems to allow hdmi and 3 usb ports, if they allow it at the same time then it would be at least possible.

it must be. did you try the smart dock?

I've ordered one and i will see how it will perform. smart dock is nice but pricey i'd like one for home and work!

Bought this one http://goo.gl/6OiGx and as it is listed compatible with the NOte 2 and the Galaxy S3 i was hoping it would work with the Note 2 as well - nope: only power OR OTG, not both.

Old thread... at least on my GS3 I have found that the ability to charge and use USB OTG at the same time is kernal specific. Anyone ever find one that works on Note 2?

[Q] [xperia t] mhl+usb+charging

greetings,
i did a lot of googling around, but only found more and more confusion. i understand that the xperia t has a microusb port that can be used for charging, connect usb devices with an otg cable (tested), and connect an external monitor/tv with an mhl adapter (haven't tested yet).
i've also come across a dock (sony calls it the 'tv dock') which is supposed to charge provide charging *and* allow a monitor to be connected - some say it has a usb port for connecting accessories, but according to the pictures and videos i've seen, it's clearly only meant for charging.
so.. since most people here are a lot more knowledgeable than me, my question is:
is there any accessory/cable/hack that allows me to connect an external monitor, a keyboard, *and* charge the phone at the same time?
thanks,
bamdad
p.s. this is my first post, so hi xda folks.. ^^

On Xperia Arc S, this is possible, because he have Hdmi port and micro USB port for charge.
Here in Xperia T, we have only one port, micro USB. I use mhl to Hdmi cable with USB cable to charge and make possible to see picture on TV for example, and I use Bluetooth keyboard with touchpad like mouse.
For me, this is all that I want, to make this feature to work.
Edit: Another possibility is to use screen mirroring function from phone with HDMI mirroring dongle to TV.

meh, too bad. i'm not really a fan of bt keyboards, because most of them run on batteries. i read somewhere that in *some* phones it's possible to get both usb and hdmi on the same connector (iirc it has something to do with it having more pins).
what do you mean by that 'mirroring function'?

Yes, the USB and Hdmi are posible on one cable. I have this one:
http://m.ebay.com/itm/281051732741
Edit: for mirroring like this for example :
HDMI CHROMECAST Dlna stream.
http://m.aliexpress.com/item/897156534.html?tracelog=storedetail2mobilesitedetail
This is for free micro USB on the phone to charge it and plug your keyboard and mouse, with USB-Otg cable to the phone with USB hub or dock Dk10 for examples.

MHL adapter for M8

Does anybody know of a working MHL adapter with at least a 12" USB cable?
I tried these and they do not work (work probably 1 out of 20 times if you keep plugging/unplugging)

Is the Skiva MHL Micro USB to male HDMI cable (6.5 feet) for Samsung Galaxy S3 (SIII LTE i9300 L710 i747... the one that works with your M8?
I really want to get one that will work.

No, only the old Samsung one works consistently which has the short usb cAble.

I bought this one: http://www.ebay.co.uk/itm/171391851548
works perfectly as I think most will.
It's all down to the sequence you plug the cables in.
Power>Phone>HDMI
Cant remember the correct sequence but try it out.
COPIED FROM AMAZON AD.
1. connect the charger to the adapter cable and power supply
2. connect the adapter cable to the HDTV device
3. connect the Smartphone to the adapter cable

I tried allcombinations before posting and none works consistently with the 2 cables I bought .
With the old Samsung adapter, it doesn't matter which order you plug in phone, power and hdmi.
I don't think all cables/adapters (advertised as 5 pin) are same. It cut open the usb part from the working Samsung adapter and it has 7 wires.
The other non working ones have 5.

If anyone is interested to know, this one works for me most of the time. Doesn't matter which order I plug it in (I usually plug the phone last though)

Its 3m in length and requires external power to work. It charges the phone although slower than MHL drains, i.e. your phone will still be discharging while connected via MHL but at a much slower rate.

[Q] MHL 3.0 and charging through micro USB?

Hi all,
I'm having two problems that I believe are related.
1) I bought the official MHL 3.0 sony cable and my tv intermitently sees the hdmi source. Off and on every second and my phone screen never displays onto the screen. Also the phone alternates saying its being charged and not being charged.
2) With some power sources, charging by micro USB alternates being charge and not being charged off and on just like the above case. But some micro USB cables/sources work just fine. As well my magnetic dock connector charges my phone fine as well. USB hosting is fine too.
Anyone has tried MHL or have had similar problems? Should I contact clove? I'm in Canada and sending it back there seems quite the pain. And if i just can't use MHL or certain cables maybe i should bite my tongue and keep the phone as is. I love it otherwise and haven't phone any faults until trying the MHL cable...

old mhl adapter works
My old mhl adapter, which requires its own power source through micro USB does work and I can mirror my screen to the TV. I just think that mhl 3.0 with power from the HDMI is not enough to drive/consistently power my phone. Same for the micro USB connectors that don't seem to keep a consistent charge on my phone. Anyone see anything similar?

Use Chromecast, the phone has a dedicated cast screen option

Yes I have used chromecast and it works great. I just wonder if anyone has tried mhl 3.0 Sony cable or has had the same chagrging experience as me.

Were you able to solve this? Im thinking about getting an MHL 3.0 cable but not sure whether my monitor will be able to handle it
