While researching ability to use USB DAC while charging the phone in the car I found this video. The guy clearly says that tablet is charging while accessing all those accessories via USB OTG. Similar cables are found on ebay, called "USB OTG with power".
The big question is: would the Galaxy S3 actually charge while using USB DAC at the same time? It should be possible, but I don't have the phone yet (still considering it), nor do I have the cable, nor a USB DAC In theory it should be the same with any accessory - can someone actually confirm either way, whether phone can or can't charge in USB OTG mode with similar cable? This video shows similar setup on Galaxy S (only it's normal OTG cable, USB hub, usb Y-cable and card reader) and it's definitely charging while mounting USB devices! Will S3 do the same?
I fear that upgrading from Galaxy S with voodoo control of Wolfson chip to north-American S3 with worse audio path might not suit me if there's no way to power the phone and use external DAC at the same time in the car... I hope there is a way... I appreciate any advice and opinions.
It's a first time I see such cable...All I read was people saying it's impossible in the first place. Well, hopefully in 2 weeks I'll be able answer your question

Looks like it's possible on some devices, but not with Galaxy and Nexus family... But it would be great if you can confirm that, so let me know if you can try it. Thanks.
Finally got the cable.
The result - nope, doesn't charge
Maybe the "Allshare hub" could do what your asking for?

Sonic, any luck with your friends phone? Really looking foward to your results :fingers-crossed:
Do you have part #s for the variable resistors in your samsung post or at least where you got them from? I would be willing to try some things out if I could find the right pieces. What I really want to get my hands on is the MHL adapter that was shown off with that spider laptop at IFA a couple weeks ago..
SUCCESS!!! I can confirm that this USB OTG cable (http://ebayitem.com/190710044655) DOES CHARGE MY GALAXY S3! I plugged in USB cardreader with SD card into the phone through this cable (it lit up and card is fully readable), then plugged USB cable end into PC and phone showed a charging icon! Moreover, after waiting for 5 min. with screen off (cardreader still glowing blue and working) battery has gone up from %72 to %75 (and while I was writing this, to 78%), so it is indeed charging! Yay! It probably won't get up in the car, where just phone alone is "not discharging" at best from the car adapter, but at least it should allow me to listen to music with quality DAC and use navigation without (or with minimal) discharging.
I have not tested it with USB DAC that I intend to use for my car (Behringer UCA222), because I have to go out and buy it. Hopefully it works. Anyway, this cable definitely works with simultaneously charging my north-american Samsung Galaxy S3 (from Bell Canada) while powering USB cardreader!
Somebody else has mentioned that another cable (http://ebayitem.com/120980364117) also worked in his Galaxy S2.
I bought Behringer UCA222 USB DAC and tested it in my car with the USB OTG cable with power that I mentioned. It works great! And the phone is indicating a charge. Sometimes when first playing music after plugging the device it sounds like fast forward for a few seconds (I guess clock rate mismatch or something similar), but after the presumably clock is locked it plays perfectly fine.

That is outstanding..gonna order one of these guys right now.
Here is a better link for all the ebay listings. Be aware of the differences, MicroUSB adapters would allow you to use your existing charge cable to plug into it while the standard USB would require you to be very close to the charger or have a USB A-A cable to attach to a power source.

The problem is that apparently not all of those cable work in terms of charging the phone. People say mostly that it doesn't work. The only guy mentioned success is with the cable I bought, but he then confirmed it with another, more convenient cable. I have the one that needs a USB extension cable to reach the charger, but it's about a buck on ebay, so no problem there. But not all cables work this way: most reportedly will allow you to power USB accessories but not charge the phone.
I found that this configuration works for charging while in USB HOST mode:
S3 -> standard otg cable -> Powered USB2.0 HUB -> devices (keyboard, usb dac, usb hdd...)
The only catch is that the hub must be powered before you plug in the phone or the phone will try to power the hub and will never enter charging mode. I'm using this setup in my car and it works perfectly. As long as I start the car before plugging the phone, we are good to go.
I only confirmed this works with AOKP JB builds. No idea about other roms/kernels. Hopefully this helps someone.

I got mine in the mail today (ordered 10/16) and tried it out as soon as I could. I can confirm it charges and allows for OTG at the same time. This is the auction I bought from: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=251127542280&ssPageName=ADME:L:eek:U:US:3160
Hello y'all. I'd like to ask your attention to this thread, especially but not limited to sonicboom and others, I really could use some help.
I have a dual usb car lighter adapter that I use for charging all my devices while I'm in the car. For whatever reason my Tab will not charge when I plug it in. I also have a usb port on my stereo that I tried but it just went into mass storage mode with no way to get it to switch to charge only. Is there any way to fix this?

if im not mistaken, the tab needs at least a 2 amp power supply to charge. most usb chargers and usb ports only put out 1 amp or less.
Is there such a thing for the GTab? I'm using mine to play audio with the GalaTab USB audio out mod, and it's a battery killer. Is there a cable that will let me connect the tab to the external charger and also allow USB digital out to the DAC at the same time? There are a number of cables out there, but none of them seem to supply power the tablet itself.
Thanks
Hello i installed a nexus 7 in my car not i really dont want to take out my center console because its a huge Pita. But i realise that i now need an otg. I was runninh sound via bluetooth to my radio but the lag os crazy. I have acces to the the end of my charging cable. I was wondering would adding a usb to usb adapter and a usb hub. Would that be consider a usb otg cable. Would i be able to purchase a usb dac and use it. Also could i charge at the same time. I have absolutely no room to fit a audio jack on my tablet. So usb dac is my only option.

You generally need a kernel installing to do as you have said eg elemental x or timurs. Yes, you can then use a usb otg cable to power and host the usb dac.
Hi all, nexus 7 2013 lte and WiFi model, 5.1.1 with timurs Kernal installed in my car.
I've got a board that has a 5v 3a power supply going to a otg y cable. Usb hub plugged into y cable and dac plugged into hub.
I've just swapped from a miniDSP MiniStreamer which is a usb to spdif coaxial sound card. This worked perfectly, I could unplug and replug the otg cable or turn power off whenever I wanted and it would always be recognized and be used by Android through Spotify, power amp etc.
I just changed my processor and it takes an optical spdif input so I changed the MiniStreamer to a hifimediy sabre u2 dac which also does optical spdif out.
I found to get the sabre u2 to work at all, I have to turn the tablet off, connect the dac and power to it, the turn the tablet on. This takes a while to do.
As soon as I either disconnect the otg cable or turn power to the dac off and back on or the tablet goes into its Fi sleep mode (when car is turned off) my tablet no longer uses it for audio but reverts back to tablet speakers.
In the power event manager it still shows the usb hub and the dac as being connected.
Would greatly appreciate any help, as it's my only source for audio in the car.
Apologies if it's in the wrong place, I've not spent much time on this forum so not sure where everything is.
Edit: do you think updating to Android 6.0 would solve this if it's just a finicky usb audio and Android 5 thing?

So I'm not sure why but a program called SoundAbout fixed this. I forced all media audio out to usb host and it seems to have done the trick.
I shouldn't need this since 5.1.1 and timurs Kernal together are supposed to make usb dac's hot pluggable but oh well, it's working now.

Hi Phahel, have you had any issues w/ static over any of your USB dac? I bought a couple of inexpensive units to try and both have static. I still have a bunch of things to try to isolate the issue (use dac on computer, use stock lineage kernel, try on another phone, etc), but I'm curious if there are any common issues that I'm just not aware of. I'm using Lineage 14.1 and ElementalX kernel (which enables OTG w/ charging). Thx!
Make sure you have quality charger and cable and that audio ground loop is not problem in your car (some Prius are known for this).
Also, I'm having problems with newer Android (7) and sound distortion. If you want to, try cm13, or stock Rom running on Android 6.

NO!
The DAC you have almot surely doesn't work with Android 6 and it's mono bug.
I find DACs can be touchy. sometimes mine wouldn't connect and I'd have to unplug, A couple times I had to reboot with the DAC connected. 98% of the time it works perfect.
Check all your wiring as already mentioned as you shouldn't need a software solution. Also check anything else USB you have connected. And when it doesn't work check PEM to see if it's recognized.
