Hi, has anyone had experience using an OTG connection that also charges the phone? And if so, do they know what pin configuration works with that? I've heard that different OEMs use different pin layouts for cables that will provide OTG and power at the same time and am curious what the Z5 family uses so I can get the right cable with my Kickstarted Superbook
Thanks for any help!

Hi together,
ive asked me if it is possible to use an adapter for 1x micro usb (plug) -> 2x micro usb (jack).
Could the phone handle 2 USB devices at the same time?
Maybe then it is possible to use the HDMI output and the USB host parallel?
For example to use an TV as screen and an HDD as the source for a movie.
This would be nice.
Thanks in advance.

When the connector is used for HDMI I doubt it can be used as USB at the same time, I'n sorry.
Maybe in a few months cyanogenmod provides a hack, if there will be an dual adapter soon.
We will see. Thank you.

The hardware needs to allow this if it'd become possible. You need a really smart USB dongle that knows how to split the HDMI output from the USB output.
Sounds a little too difficult to ever happen.
Hmm thats right. I think i still dream xD
But thank you.

it is not possible. because as stated on this forum many times before, the type of usb connection is determined by the resistor between pin 4 and 5 of the micro usb connector. the strength can tell the phone, that there is either a charger, a pc connection, car kit, jig, usb otg or mhl connection present.
and i believe, this is an important thing to keep in mind for so many things:
for instance, why the original car kit triggers car mode and generic car charging cables don't or why not just any micro usb male to usb a female will work as a otg cable or why flashing should be done with the original usb cable...
so if you were to buy or build a micro usb hub, since it has no resistor in the very plug that connects to the phone, it cannot be used for anything but charging and quite frankly, i wouldn't connect more than one charger to the phone.
however, if you want to use your phone for presentations or watching movies and still be able to use it, get a bluetooth keyboard and mouse or a bluetooth presenter or do it the other way around and use a usb input device and transfer your media using allshare. everything else is physically impossible, so neither CM nor XDA can do anything about it. the only device that can do what you want is the new motorola. it has a separate micro usb and micro hdmi port and a docking station, so you can use it as a full notebook.
Thats obvious. Thank you.

However, is there any way possible to charge your phone WHILE using the OTG adapter? They both use the 1 micro port on my phone, but I need to find a way to charge the phone while using the OTG adapter.....perhaps a micro USB splitter-type adapter?????
I was actually wondering about this myself, though I don't think a splitter-type cable would work. I'm wondering if the power connection is on separate pins than the data, though...if they don't share space then I'd think it would be possible in some fashion.

A similar problem is showing up regarding using the mhl port to output to hdmi. Though the original information indicated that the power cable was supposed to charge the phone it seems it does not on the first version (super DUMB).
I have read though that the newer version of the mhl port is 10 (I think) pins rather than the 5 of the original. The newer port DOES allow charging while output is in operation.
I suspect this will also allow an OTG cable that charges while in use.
I am not so sure about the mhl idea anymore. Only one port for everything is ok if it has enough pins/bandwidth to have a breakout box that would allow an external usb drive to be read while hdmi is being output to a screen and power is supplied to the phone. As it is now with only one-at-a-time it isn't very inspiring as the phones get closer to the power of laptops.
What would be really neat would be a box with wi-fi, and the output to hdmi and usb ports as well. A wireless breakout box. Then the charger could be over by the phone which is near the user.

I think this thread could solve your problem.
Oh... I found a useful diagram here.
Hi!
It looks like it's possible to use some USB Ethernet adapters with some Android tablets, but is it possible to have it running on AC power at the same time?
I suppose that this can be achieved with some special OTG cable, if it is possible at all. Have anyone been successful with this?
Please share what's your setup, i.e what tablet do you have, what Ethernet adapter works with it, and what kind of OTG cable are you using.
Direct links (Amazon, eBay, etc...) are very welcome for Ethernet adapters and OTG cables.
Thanks in advance!
PS: Hopefully this is the right forum to post these type of questions.
Hi, I tried with a otg cable which had an additional port for power but it's just for when u use hdds who needs more power then 450 mA to run. Android is not allowing to charge the phone during USB otg usage.
Hi everyone, i have a question.
I wonder if all device that shipped with a USB type-C specifically a smartphone, is able to supply power to other devices ( eg. Charge a phone)?
I have a Samsung Galaxy A7 2017 which comes with USB type-C. I failed to use OTG on this phone. I tried connecting it with type-C OTG connector to charge my other phone but it does not seem to charge.
I have no problem charging or connecting the A7 2017 to my computer.
So I believe that the phone is not supplying power from its type C port.
Therefore, I'm wondering if all USB-C port can output power/ supply power.
Could it be a faulty USB-C port or it might be a software issue?
Any solution to this issue?
Any answer and suggestion is very appreciated. Thanks in advance.
I guess some can. Google might help. My Pixel for example is able to charge another phone!
I am just guessing on this one, but I believe that it might be a software thing, because if you remember the "good 'ol days of usb otg", some devices didn't support it because of software I believe.
Apologies in advance if this has already been asked and answered.
I'm interested in using my USB-powered DAC to send an optical audio signal into my digital signal processor in my Jeep. The obvious problem I face in doing this is HEAVY battery drain.
I used to run a 2nd generation Nexus 7 tablet as my head unit in a previous vehicle, which could power by USB DAC while charging with the use of a Y-cable. This doesn't seem to be the case with my S9+.
Do any of you know of a way that I can achieve this with the S9+?
Thanks in advance for your help!
Just thought of something...
I'm guessing I could use the DeX dock to charge while using the DeX's USB port to power the DAC. That SHOULD work. Alternatively, perhaps I could wirelessly charge the S9+ while powering the DAC via OTG. Either application (if they work) would only prolong battery life, as I imagine the drain would be greater than the charge.
Anyway, still wondering if there's a way to get an old-fashioned charge while using OTG with a Y-cable or similar (powered USB hub?).
Bump. Curious if anyone has had any luck with this. Thanks in advance!

i dont think youre going to have much, if any, luck on this man. USB type C is kinda weird like that. There isnt even a jig for type c like there was with micro. Im following this one too.
There are aftermarket devices available that provide you the capability of using a USB along with a charging port and a HDMI output. I have tried it myself using a mouse and charger while connected together with the phone..... You could give it a try. That should work and is inexpensive too. I bought one and still use it sometimes for my Dex needs.
