found in some other post.
"the connection between pin 4 and 5 determine, what kind of connection it is: charging, sync, usb otg, mhl, trigger download mode... and indeed, that is done by putting in different resistor strengths."
is there anyone out there that has a GNexus and a xoom original camera connection kit to try, see if is the same as what i get which is nothing?
thanks.
I tried my Xoom cable too and nothing worked. So what cable do people suggest using for the Galaxy Nexus? Is there a Samsung one guaranteed to work or will we have to just find some and try them out?

I got the Xoom Camera kit cable to use as an otg cable for my galaxy s II. When I plug it in, I get no notification or any sign that the phone recognizes it. I also tried pluggin in a pen drive and changing roms/kernels but nothing works. Is the cable defective? Or maybe I got the wrong one? Any help would be appreciated.
please help. I dont want to return the cable for nothing
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??

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.
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.
Hi All,
Has anyone tested the new nexus 7 (2013) with a slim port and tried USB OTG at the same time?
I am very keen to find out if i can use a Nexus 7 as a portal Media machine to play back movies from a thumb drive on Hotel TVs when i travel without the need to move the file.
I understand I'd lose ability to charge the nexus 7 using USB OTG (OTG limitation) but I can live with that.
Thanks for any results
Tony.

AFAIK the Slimport cable needs to be directly plugged into the USB port so it can switch the Nexus 4 from standard microUSB to Slimport broadcast mode on negotiating with the hardware. If you attempted to run the Slimport adaptor through a hub or Y-cable it wouldn't work.
Thanks,
I was wondering if I could plug an OTG cable into the female on something like:

I have attempts to connect an OTG cable to the female port on my Slimport without any luck. The Slimport worked well otherwise.

Yeah, the microUSB port on the Slimport is for power only, the data pins aren't even wired up.
Suppose I connect Nexus 7 to a monitor through SlimPort. This monitor has USB ports built in. If I connect a keyboard or mouse to this USB port, will it work with the tablet?

No - this wont work.
As stated above the data pins on the slimport are not connected so the USB can't be used for anything other than power.
ie. Tablet can't do anything else over usb when the slimport is in use.
Bluetooth keyboard + mouse could work for you though

Thanks. My intention was to use the tablet as a PC alternative for my parents. I have dropped the idea. Now I am thinking about getting one of those Android mini PCs instead (thread here).
The issue is the limited number of pins on the Micro USB port are multi-purpose.
A Micro USB port has 5 pins, one is power and another is ground, that leaves 3 for data. These 3 "flip" (for want of a better word) between USB mode and Slimport mode, So it can only do one or the other at any time.
So the lack of data pins on the slimport pass-through port (as stated above) is not the issue. They didn't bother wiring them up because they share a couple of pins in common and so wouldn't work anyway.
[Edit]
Just to clarify a slimport Micro USB connector has 5 pins. Samsung on the other hand are now using MHL 3.0 and they are pushing on with an 11 pin connectors that open up all sorts of options such as simultaneous data connections and even multiple displays! nice!

Exactly. SlimPort™ Technology White Paper has a nice explanation along with the good picture showing SlimPort architeture (see page 4)
Hi guys, do you know any cable/adapter that has all these ports?
I'd charge my tablet while I've a pendrive inserted into it and connect all via hdmi to a monitor/tv.
Did anyone try something like this? I'd like that all ports work all together at the same time.

Something like this? It has USB in, although I'm not sure if that's for pass through charging or just device inputs...

I have one of these and it works with Note 10.1 2014 - to some degree.
Basically HDMI and USB work - at the same time.
I can connect my tablet to external screen and use USB mouse, keyboard and flash drive (through USB Hub) all at the same time.
But... USB connection is kinda unstable - devices disconnect occasionally and then reconnect.
Also, charging doesn't work at all.
On my Note2 everything works OK - I guess Samsung changed something either on connector or in software in Note 10...
