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.

Anyone know if it's possible to use MHL in conjunction with a microUSB to USB host adaptor to output to HDMI and access an external USB drive at the same time? That'd make the SGS2 an amazing portable media unit.
No, it is not posible. Its an either/or connection to the micro USB port.
Shame, because as you say that would really be a great thing. MHL consortium are considering a number of improvements to the 2.0 MHL spec, so in future devices this may be a possibility.
So MHL can't be used when I'll plug a USB-Hub?
No, sadly not.
It's a shame - for now I'd prefer micro USB & separate HDMI port so USB can be utilised as well as an external display.
As would I, and a lot of others I suspect.
But you've got 16 GB memory and can copy your stuff to the memory and watch it later via MHL on your Flat? So this is not a big problem, I think

Not that I'm aware of...
I bought one from Ebay and can't really do anything good with it. Display shows briefly for 3-4 seconds on TV then disappears again. Don't know why.....I hope it's not the device itself because I tested 2 phones, they were bought at the same time, but none of them would work correctly....
If by generic you mean a not samsung one or one not dedicated to the SGS2 then i actually use a one, from ebay or someting like that, everything works perfect you just cant forget to plug power to it, and about the not working one, it seems mine gets jammed by gsm signal (i.e. when receiving a call), so from time to time the image disappears in a blink of noise, maybe that is your problem too, try it in airplane mode.
Oh, I think I misread that question - I have actually used a generic one with my SGSII (a prototype from the MHL consortium) and it worked fine!

Uhm no. I've been streaming with WIFI through MHL no problem for MONTHS. Using the Original Samsung MHL connector of course.
I have to put mine in offline mode to be able to use the MHL adapter.....
As for USB-OTG no luck yet.....
On Amazon, Ebay, DealExtrem ... you will find adapters that can do 3 things at a time:
- output HDMI
- let phone work as usb host, so that you can plug kbd, mouse, and external HDD (second wifi card, wired ethernet ...); once you have the usb A plug, just pub a hub
- recharge the phone (what is not possible with the legacy short OTG cable).
+ read memory cards
Such devices are sold as MHL devices. Some MHL devices don't to all that.
Take care. MHLv2 is more complex than MHLv1.

Could you post a link as an example for such a device, that works properly (if you've tested, or you know it works) ?
Thank you
I can post links, but ... I have not tested any of those. And don't know any one personally who tested it.
Cable:

Monobloc:
http://www.ebay.fr/itm/Micro-USB-Ho..._MobilePhoneDataCables_JN&hash=item258600844e
I don't like the monobloc version; I fear it's too heavy, and may help breaking the phone plug.
There are all sorts of OTG and MHL cables. I have seen OTG dongles as short as 4cm (monobloc), with small cable (8cm: 4-8€), with long cable (1.5m .... should be 7 feet), pure HDMI (passive cable, no card reader, 8-12€), VGA (including very cheap HDMI to VGA converter, 20-30€ ... including sound output). In some case, you need to buy accessories (extra power supply, extra uUSB cable, extra HDMI cable). Also seen a very cute hybrid card reader: http://dx.com/p/285865 (I love this product design, and I love this URL syntax )
Don't forget that there can be mistakes in item description.
Here I have described how to build an external battery:
http://forum.xda-developers.com/showpost.php?p=54036759&postcount=17
On previous phone, I just soldered additional battery to internal one; on my new phone, I will do something more complex, and more flexible.
Loosing power via OTG/MHL is not a fatality. Most phone have an other hidden power input:
généric, that uses the USB plug:
http://www.dx.com/p/reverse-qi-wire...arger-receiver-for-micro-usb-cellphone-312805
TRIPLE CHECK POLARITY; I took the wrong one; have to fold the cable.
So ... even if your OTG/MHL module takes power from your USB, and can not recharge your phone, the specific shell can charge your phone the other way So, you need to build an internal specific module:
https://www.youtube.com/watch?v=UK7PRJ4SiK0
S2 specific back shell, so called receiver:

http://www.alibaba.com/product-detail/QI-Wireless-Charger-for-Samsung-Galaxy_821969998.html?s=p
The SGS2 is not designed to accept wireless chargers, so, you have two options:
- solder and take the pins out (cf youtube) (do not solder coild to battery, or you could overcharge the batt, and burn your phone ... I mean, physically set fire)
- find an item that includes back shell + specific battery (exportprive)
Many recent phones have the internal connectors, so you just need to change the back-cover. In this case, the software will be able to know the charger is wireless (as opposed to AC, and USB; advanced battery tools will show those 3 possibilities). I believe the motherboard for my HTC One M8 is designed to have those pins, but I can't find the specific cover yet (maybe in a few months); only found it for M7.
I just ran across this USB Card Reader/Hub for the Samsung Tab. The device has three USB ports and a card reader. It even has a plug for a 5V power supply.
http://www.ebay.com/itm/SAMSUNG-GAL...=Laptop_Adapters_Chargers&hash=item2316d2ac0e
Has anyone tried this thing? Does it perform as advertised? If it does, it may be the perfect accessory, especially when teamed with a power supply. On that subject, I wonder where one might find a compatible power supply that would provide the right amperage so it would work with the Tab.
Bob
^I would like to know also. If it works like it says, that would be the best thing ever!
I asked the company posting the device on eBay if they offered a power supply that would supply 2 amps. They said no.
Here is a question for some of the smart guys on this forum. Could the Tab be powered by a male to male USB cable plugged into the standard Samsung 110 V power plug and then in to the hub? The next question is if everything could be powered using a USB car adaptor that puts out 2 A.
Bob
Bump! Does anyone have experience with this device. If so, please post. Also, if anyone can answer the questions about the the power supply or USB charging from a car outlet, that information would be greatly appreciated.
Bob
I think you are misunderstanding the use of the power supply. I'm pretty sure the power supply doesn't charge the tab. It only powers the USB appliances (mainly for HDDs). An active USB-hub if you wish.

I am sure you are right. I wonder if the the Tab could be charged if a male to male USB cable was plugged into one of the USB ports and then to the stock Samsung plug?

Great, you are just the guy I have been looking for. If you can come up with a male to male USB cable, plug one end into the device and the other into your Samsung charger puck. I am curious if the Tab will charge using this method.

Well, that depends on the hub. How it is designed. It may block current from flowing into the USB ports.
I have to check mine when I get home...
Mind you, USB current is limited to 0.5A and that isn't enough to charge the Tab and use it at the same time.
But, let me see if I understand what you're trying to do: Connect the 110V adapter to one of the USB ports. Power/charge the Tab through a second port.
As to your earlier question,about a vehicle equipped USB port... Same answer. It depends on how the hub is designed. Since I have Sync in my Ford I have a USB port and I can check that as well. I know the Tab works connected to it... just not a USB hub.
how's the test
so... any result from your test? can it charge the tab?

I can't find my male/male USB cable. (I live in Alabama, and that sort of thing is against the law. )
OK guys, about to order a livedock but wanted to quickly check if there was any other cables available to enable me to charge my phone while using the OTG function.. Seems the whole mobile community is looking for this.. Samsung galaxy S2 users are even worse off because they can't use Hdmi at the same time as OTG! I've looked all over but seems Sony Ericsson is the only company to have made a charge while using otg dock /cable any other ideas from you smart folk? Before I splash out on a livedock??

Sent from my MT15i using xda premium
meh.. after quite a bit more googling I have come to the conclusion that the Livedock is infact the only way to charge the phone while using USB OTG.. I can't quite believe that there isn't simply a Y cable to do this.. (but I havn't been able to find one anywhere)
I have just ordered 2 livedocks from Ebay.. can never have too many right (well.. one for the tv and one for the bedroom)
The plan is to be able to have the phone plugged into the TV HDMI and a self powered USB hub (logitech wireless keyboard and mouse, Game controller + USB hard Drive\thumb drives for movies\music) and also charge the bad boy all at the same time the one next the bed is just for charging and perhaps a USB keyboard for those late night emails. (yea I could use Bluetooth, but these are still expensive and the extra hassle of pairing keyboards and mice to the phone is un-necesary when SE have given us good old fasioned OTG)
still interested if anyone finds out a different way.. I might pull one of mine apart and see if I can reverse engineere to make a simple Y split cable..

In the samsung galaxy s2 this is not an electrical but a software issue. As an experiment turn off your phone. Connect a usb Y cable to a power source and to the phone via the OTG adaptor. Hey presto, it charges the phone through the otg connector.if you now connect a usb device to the other connector on the Y the phone wiill not see it. Likewise if you connect the usb device and the power THEN connect the cable to the phone it will see the device but will not charge. Both variations with the same bit of dumb cable and the same devices on the same connectors. Something in the usb / charging control software must be blocking both otg and charging from working concurrently.
Hi is it possible to sold an USB-OTG and Charging Cable in one, because OTG is draining the Battery so fast
Greeds
sPeEdX100
Sorry can't be done.
It is possible with Livedock. OTG and charging in the same time, so I belive there is chance for SGSIII too.
It is possible with a diy cable. I made mine from and old micro usb to usb A data cable (the one you use to connect a phone to pc), a hardware switch i scavenged from an old radio and a usb extender cable (you only need the part that has the female port to stick other devices in like flash drives. i use the switch to toggle from usb OTG mode and standard data/charging mode to connect to pc. I think you can't charge and use usb OTG simultaneously. for that you could wait for a wireless charging mod.
I believe this might do the trick (have a look at he video as well).

I'm considering upgrading from my Galaxy S (with voodoo sound and wolfson chip) to Galaxy S3. I'm on Bell. I understand that north-american version does not have wolfson chip and audio is worse than original S with voodoo. I use it for relatively high-quality aftermarket car audio using analog out to audio aux-in.
What are my options for S3? What's the cheapest usb dac I can use with north-american s3 and where to get it in Canada or US online?
Is there any guide about how to set it up?
Thanks!

No wolfson chip for NA version hopefully we get Voodoo kernel soon. Until then, some people have had success using a Fiio e7 plugged into their S3 using USB OTG. As for how they did it, I have no clue.

I did some research on this. Apparently it's possible to plug in a whole bunch of USB OTG devices, including many USB DACs. However as USB port is occupied - they suck power from the phone and phone itself cannot be charged at the same time. There are cables that you can inject USB power but in Galaxy S3 case - only to devices, the phone itself switches to "give power" mode when working in USB ORG mode and does not accept charge over USB. This is a bummer, as there is no way it can hold a battery for long while playing music and working as GPS in a car.
There is a guy on another forum who mentioned that it's possible to force S3 to accept charge with change in kernel (that means it won't power other USB devices, but they can be powered via injected power), but this is beyond my ability. We need somebody who knows how to do this to either build an app, or do a kernel version (semaphore?) or both, that have this module disabled on demand.
Here's what he said:
" However, I was able to modify this kernel to make it accept a charge while in OTG host mode. A Y-cable is connecting my phone to a powered USB hub. The hub has a USB-to-Ethernet dongle, connected to a router. The hub is also powering the Gnex via the other end of the Y-cable. The phone can now, say, act as a WiFi access point (wired + 3G!) and it's battery level will never drop below 100% or 99%. One disadvantage: in a real on-the-go situation, this kernel will not anymore power slave devices. One could fix this by allowing the user to switch between OTG host mode charge-out (default) vs. OTG host mode charge-in."
" On the Galaxy Nexus, removing the complete body of method tuna_set_vbus_drive() in arch/arm/mach-omap2/board-tuna-connector.c will disable charging of OTG slave devices and will allow the OTG host itself to be charged. The battery icon will not be updated by this modification alone."
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!

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.

Sorry for double post, I posted it by mistake and can't delete the post. Button says "edit/delete" but there is no delete option, just edit...
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.
There is a big list of working DACs in the official sound quality thread, along with a lot of other good information.
midirt,
I am working on a car setup like this and would like to ask a question. Somewhere I read that you had to plug microUSB into phone before plugging into DAC in order for it to work. Is this true for you? It would be a pain to have to unplug everything each time you get in car.

Usually I just plug entire setup into the phone and it works fine. Sometimes when I shut off the engine and start it up (there is power interruption) I have to re-plug the DAC.

It's not perfect though: there is definitely a "dirty ground" noise when power is connected - it may not be its fault, I'm using a weird aux-in adapter and all other solutions I tried had the same problem, even phone itself, when connected to power supply. Disconnecting power supply there is no noise. It' not usually noticeable in the car, but it's there and I don't like it. If your car doesn't have noise when phone is connected directly to aux-in and plugged into power, this unit won't have that noise. I just wish they would separate ground or cleaned the power or did something to isolate noisy USB power, but it's too cheap to have that. Nor sure expensive ones can do this either. Ground-lifting transformer from ebay removes the noise, but also reduces quality so I'm not using it.
Another issue is sometimes in the beginning the sound just accelerated and is played fast-forward for a few seconds, then it catches up and plays normal. After that it works OK until restarted. Very weird and a bit annoying but not a deal killer.
