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?
Sent from my Nexus One using xda app-developers app

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?

OTG w/ charging

like most MHL cables that include the charging port (where you just plug in from wall), is there anything like this for OTG??
tried finding and searching but nothing.....

If you're looking for power going to the USB device, then you can use this.
If you want to charge your Note while using the OTG feature, then I've not yet come across anything like that.

Just wondering if it is possible to charge the Note 2 while using the OTG yet? I'm in my car all the time and use an external SD card. My 64gig internal card is already full.

How about a scenario where I have External Battery charger and OTG adapter with usb stick. I want to watch the movie on usb stick while also have External battery connected charging the phone. I guess it's the same problem as not being able to charge up phone from any external source while using another device connected to OTG?

You could make your own micro USB OTG cable. I still haven't seen one for sale anywhere.

Oh, I don't have issues with OTG cables. I have adapter and cables, and modified cables before: http://forum.xda-developers.com/showthread.php?t=2107985
I just want to figure out how I can watch movie from usb-stick while charging my phone at the same time. There seems to be no solution for that yet? Or are you suggesting there is a way to make a custom cable to do that? I think once you attach OTG cable to connect a peripheral device, you turn Note 2 into host and it will not accept charging from micro-usb port. No way around it

Oh, I understand what you mean now. In that case, you are correct. You cannot charge your phone and use an external thumb drive at the same time through the usb port. When you plug in an external drive, your phone switches the USB power cables to send the juice instead of receive it.
The only ways I know around that are to use a wireless charge stand or the desk dock.

Isn't this exactly what sammys smartdock does? Charge and otg simultaneously?

Yep. Not possible with just a cable. It needs a microprocessor to regulate the current in and out. Devices plugged into the dock are powered by the dock's power, not the phone's.

I hear what your saying, but looking at threads in the S3 section like this one: http://forum.xda-developers.com/showthread.php?t=1953061 got me thinking... I'm just trying to make an audio cable for my car that charges and has 3.5mm out to my radio. And I need it to work with every 4.1.X kernel and above, especially stock.

If you get a pinout for the s3, might be able to modify a cable to do both.

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)

http://www.amazon.com/gp/product/B009LAZG2M/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
I have an old samsung (link below) which works but the USB cable is very short

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

USB C audiooutput & USB-DAC

Hello!
Maybe someone know, how to use USB C audio adapter with Realme X2 Pro?
I tried to turn on USB OTG, but it not doing anything.
Adapter: Baseus Type-C Male To Type-C Female +3.5MM Female Adapter L40
How I can see, it has audio chip inside, and working like DAC, maybe.
Sorry, I have no rights to post links.

I just got the Meizu USB c amplifier today, and I had a hard time getting it to work as well. I also turned on USB OTG, then after plugging it in, taking it out, and putting it back in again, the phone recognized it and I could get audio over USB c.
It may not work for you, but also try flipping the connector over. That may help as well? I'm not sure what got mine working, to be honest, but it did work eventually.

Sorry, it's not working for me.
Also, yesterday I tried to use usb flash throw otg - it's work fine.

Try the usb configurations from developer options
Set it to Audio source
