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.
Does all usb to micro usb cable work with xperia ION for charging?
The original cable is way too short, i just bought one, it wont charge properly, only transffer data is ok.
I use many cables to charge. I use Galaxy SIII charger, old Sony Ericsson Aspen charger, Nokia 500 charger, Nokia Asha 305 charger, Xperia Neo V charger, Xperia Arc charger, Galaxy SII charger, Galaxy S charger. I tried all these cables. All work for me.
I believe you may find 2 types of cables.
One can do both data and charge.
The second will only charge, this cable will lack the data wires inside the cable.
Both will charge.
I have only read about the charge only cable.
All standard micro usb I have used can do both.

I had recently purchased the C6502. At work I do not have AC power outlet to charge the phone. So I generally used to charge my old smartphone (LG Optimus 4X HD) with a blackberry USB cable. I used to charge my old phone by connecting to the monitor's USB port using the blackberry cable. Though the phone showed as "Slow charging", it served the purpose.
But now using the same Blackberry USB cable and the same USB port, if i try to charge the C6502, it just lights up the screen and does not show any charging indication or the notification LED light.
Am I missing something here or the phone charges only with the original Sony provided USB cable?
Note: The same USB cable and the USB port work perfectly fine for other smart phones my colleagues are having like Galaxy grand, Lumia 610, HTC Desire SV etc. Of course when connected to the usb port all these phones are showing as slow charging, but they do charge slowly. But my XZL does not even charge. So I am definitely sure the cable and the port are perfectly fine.
Is there a way I can charge my XZL with the USB cable using the USB port?

Let me explain it more clearly.
At my work the USB ports on the CPU are disabled. But the monitors are having USB ports which can be connected to the CPU through another cable, so that USB devices can be connected to the monitor's USB ports insteading of leaning till the CPU under the desk. But those ports are not connected to the CPU so the ports on the monitor just act as a power source but not as data source. So we use the monitor's usb ports for charging our devices like phones, ipods etc.
As i had already told that my XZL screen lights up when connected to the port using the blackberry cable, but no indication of charging as well as no LED light. Same case with another colleague's Xperia SP.

So sony does not support "chaging only" mode using USB cable. How pathetic !!!. Supposed to be a "Smart phone" but really do not understand why cut down basic features.
Can anybody confirm if this cut down of a basic feature is a standard for Sony phones?

USB charging
I have observed two things -
1) Yes, it does not charge in some cases. I have a power bank cable, with this cable it charges for some time but then it just stops charging without any reason. If you reinsert the plug, it starts charging again.
Other times, it does not charge with USB ports, for example my car music player's USB port. But what I have noticed is, if USB connectivity mode is changed from MTP to MSC or vice-versa it works.
Also some cables do not have two spring notches, and fit quite loose. In such cases pushing cable vertically up or down gets it charging again. But this is very very rare case.
2) I was not able to charge it from front USB port of my PC, but when connected to back USB port, it was charging fine.
My conclusion is, it does not charge if charging rate is too low or mode is incorrect.
I would suggest, try with original Sony USB cable in your office and check if it works. If still it does not, change connectivity mode. Else its a cable issue(not exactly, but phone and cable have some mismatch).
PS - I had similar problem with my chinese tablet. Out of more than 5 cables, It charges with only one cable from Nokia(it does not even charge with original tab USB cable ). I think there are separate data pins and power pins. But data pins can double as power pins. I think there was some damage to the tab USB pins, because of which data pin no more works as power pin and hence it does not charge and requires cable having power pins. Can somebody throw more light on this?
Relax its just u need a pc on to charge it it happens in my case too n my phone works fy9 with any cable

Do i need a custom Kernel to get that capability?? I have a OTG cable that works for connecting a mouse, keyboard, thumbdrive etc and it has a port for power but the tablet does not recharge.
So i'm wondering if i need a custom Kernel or maybe the cable is defective or something.
If you know of one of those cables that work, please let me know.
Thanks in advance.
I have this cable out of China:

And also charges simultaneously? That's what the OP is asking for.
Slimport adapter outputs HDMI signal and lets you charge the tablet simultaneously, but besides that... nothing else on stock ROM I imagine.

Bummer! That's what i was afraid off.
Hello I have the same problem! : (
I installed the tablet in my car but you can not use the charger + OTG simultaneously.
You have to wait for someone to change the KERNEL as they did for the Nexus 7.

Hi everyone,
I had same problem!
My pad is rooted, 20b, stock kernel, Finally, find out solution.
I bought IBUFFALO usb with AC power around 15USD. 4 Slots for USB 2.0 and 1 double micro usb. Worked with mouse, Bluetooth keyboard, external drive with USB 2.0 only, usb 3.0 not work. Just for your info.

Difference between normal and OTG USB cable is that OTG has pins 4 (sense) and 5 (ground) shorted and on regular cable pin 4 is not in use. If you put a switch between these two pins you can switch between regular USB cable for charging and OTG for connected devices.
Some apps can be found on Google Play Store that claim to be able to switch between or enable simultaneous OTG and charging, but most are for specific devices or group of devices, none for G Pad 8.3. Most promising is maybe Faux123 Kernel Enhancement Pro (3.77€ and requires Root+Busybox+SuperSU).
Too bad our tablet has no secondary charging port (like Sony has magnetic charging port for example), but least intrusive would be to use powered USB HUB, let it power the connected devices so the battery drain on the tablet will stay low.

Thanks for that - Very good info! Allow me to pick your brain a little more: Looking at the cable i have (in the OP), do you think that by just connecting an external power (red and black) to the cable just before going into the tab would work somehow to give it power.
It's intreging what you said about being able to switch from regular USB (that can supply power) to OTG just by jumping those wires. I'm trying to picture something in my mind to accomplish what we want but the "light bulb" haven't came on yet - any suggestions?
I want to use the tab in the car PERMANENTLY so i need a way to charge it while behind the dash. I would want to use a mouse as well so OTG is a must.
In any case, i'm going outside right know to split open that cable and see how it's connected inside, maybe then the light bulb will come on in my head.

Try it out, you got the cables!
When pins 4 & 5 get shorted the tablet may be configured only to output power, not receive it. I have only OTG adapter cable and the supplied USB charging/data cable, so I cannot test this stuff.

I would buy micro USB male plug, some heat-shrink tubing with glue, switch (3A) and split OTG adapter or HUB. Cut off the male plug fom the adapter, solder on the new plug to the adapter cable as normal USB, solder on the switch to pins 4 & 5 of the plug, check it for continuity and shorts, test it on the tablet, if good - secure the new plug to the cable with heat-shrink tubing.
EDIT: Possible solution with resistor described here
Our device, if it can be tricked this way, may require different resistor from the one used in the tutorial (usually in 36KΩ-200KΩ range).
Ok, I'm chopping it up! I spliced-in the red and black wires from a USB cable into the OTG cable (in the OP) and sure enough the tab gets power. However, it no longer detect the mouse or any thing else (kind of expected). Tomorrow i will try bridging pin 4 and 5 and see what happens. If that don't work, i will try the resistor. :fingers-crossed:
I have read that devices on OTG get polled regularly, but charging is not, i.e. if you start charging and after that short the pins 4 & 5, it will continue charging and you can use your OTG devices. Hope this holds true to the G Pad as well.
Isn't micro USB a "standard"....??
Then GEEZZ why do one manufacturer thinks it's ok to eliminate a pin completely! i assume that when i pay for that cable, i will get ALL 5 PINS even if one is not connected - rip-off! :laugh: This manufacturer not only didn't connect pin 4, it was eliminated completely; stopped me in my tracks! Fortunately, i have an extension that have of all things ALL 5 WIRES CONNECTED! Imagine that! But now, i don't have any time to chop-it-up until tomorrow. With the 5 wire cable, i will short the yellow and black wires but I'll check here first to see if I'm warned against it.
More to come..
Hi manny your car kooks awesome. I have one question. How you connect your speakers from the car with the G Pad. iam also interested to built a GPad in the car !

Yep weneed more info on this as i would like to fit my pad in the van,, how did you get fm radio on there.
Nothing good to report. Connecting the power wire to the OTG cable and shorting the 4&5 pins does nothing different. I can have it charging and when i disconnect power, it then detects the mouse (that's a good thing) but when i plug the power back in, nothing happens! Ideally it would disconnect the mouse and start charging again but no-go. Having the 4&5 pins shorted or not makes no difference.
Still have a couple things i will try before i give up, one is the resistor and the other is a more simple OTG cable.
Will report back.

I understand that you would want the cables all hidden behind the dash in a car and can't be connecting and disconnecting plugs all the time, at the most just flip of a switch should make things work. The resistor trick would be ideal, if it works.
What's the exact sequence you did things in?
- Mouse and charger connected to the tablet simultaneously with pins 4 & 5 not shorted, tablet charging - short pins 4 & 5 - what happens?
- Only charger connected, pins not shorted, short pins and then connect mouse...
- Mouse and charger connected to the tablet simultaneously with pins shorted, mouse working - unshort pins...
- Only mouse connected, pins shorted, unshort pins and then connect charger...

I would have to record in what sequence i do things to remember but it seem i have done every combination possible. I do remember doing these sequences after a fresh reboot of the tablet and BTW i made a simple cable out of a know working (single) OTG cable and splicing-in the red and black from the cable that has 5 wires connected, leaving the pin 4 wire disconnected and extending a pigtail from the black wire so i could short the yellow and black to hopefully force OTG:
- Power plugged in and mouse plugged-in then plug the cable into the tablet - it detects the mouse but does not charge.
- in the above state, shorted the yellow and black wire - no change.
- separated 4/5 then disconnected the mouse leaving power connected (expecting that the tab will then switch to charge but) - nothing. The mouse did disapear but the tab did not start to charge.
- shorted 4/5 (for ****s and grins) and as expected - nothing.
Again with a fresh tablet:
- with (ONLY) power connected to the cable, inserted the cable into the tablet - it started charging.
- in that same state, connected mouse - mouse was NOT detected but the tab continued to charge.
- with mouse plugged in, shorted 4/5 - no change (charging but no mouse detected)
THIS IS THE IDEAL SITUATION BUT JUST HALF WAY:
Rebooting the tablet with both power and mouse connected and cable inserted, the tab starts by accepting the charge (no mouse) but get this, plugging-out power makes the tab switch to the mouse right away! That would be good except that plugging the power back in does NOT make the tablet switch back to power, in fact, nothing happens, the mouse just continues to be detected.
If i had 2 cables, one only for power and the other only for OTG, i could pull one out and replace it with the other and both functions would work; i don't understand why that same "switching" can be recreated within one cable??
This is beyond me, the last thing i will try is following your sequences to the letter and with the resistor, if that doesn't work - i give up! :crying:

since i got tablets, i miss the possibility to charge and use usb at the same time. And so,i tried a lot of adapters. On my note 10.1 2014, i tried one, from samsung, that was specialised for the note pro 12.2, sorry,dont know the exact Type,but i bring it,promised.....
Also with my tab s2 9,7Lte (815),i try different ones,but no one work,till i try this one from samsung again......and.....it works perfectly. The TabS2 have a build in ethernet interface (settings, other connections, ethernet). I plug in a ethernet cable,work....... plug in charger.......work......then i connect my IRig UA,got power and it works.......charging not interupted, ethernet still working......and the adapter have two Usb 2.0 Ports and 1 Usb3.0 mini Port (like Note3) for charging, but also works with a micro usb 2.0.........
Thats fantastic......i be absolutely happy with the tab S2.....got root now, amazing power.....great device samsung......
The only prob is, some apps don't support ethernet for internet connections,like chrome and others. There is a tool for xposed, calles fake wifi connection, but Xposed don't work at the moment,about my Rom isn't deodexed......but soon, i think.
Or anyone got another solution for this?

In my company, we have a VPN network, Remote desktop Connections and all the Admin Stuff is working fine...... You can configure the Ethernet Settings automatic, with dhcp or you can set a fixed ip adress and set the subnet and Gateway ......
I tried it with Ethernet, charging, and two USB Ports running a Audio Interface, and an USBStick on the other....perfect....

Hi
I have the Tab S1 running stock kitkat 4.4.2, My windows computer is an HP 20" tablet and it came with an hp usb to ethernet adaptor, after reading this thread i decided to give it a go, and it works great and i did not have to change any setting or install any software and i can browse the net with not problems.
So it looks like non Samsung usb to ethernet adapters can work as well.
John.
Yes, the ethernet adapter is no wonder.......more interesting is that USB and charging work also.....normaly, the usb port on Android tablet is physically so configured, that is can only charge or Power a usb device....(of course a kernel thing also).....and on the Tab S2 work all at the same time........
on Android devices should work every USB to Ethernet Adapter via OTG Cable, or you find a micro usb to ethernet......
On the note 10.1 2014 LTE, i found no adapter, that allows to charge and using usb at the same time, including the Lavalink adapter, that should.....
Gesendet von meinem SM-T815 mit Tapatalk
@john, browsing the net is no problem, but some apps,playstore also, needs to have a WiFi or 3g connection. (Try to download an app in playstore with ethernet) so you need for this apps a tool, that fake them, they have a 3g or WiFi connection. That's not a problem of the adapter, that apps aren't made to run with lan . This problem can be fixed with eth0 app.....

I made my own USB OTG cable and with an 82k resistor on pin 5 of the USB cable it charges and does OTG at the same time. Note however that it also keeps the CPU awake so you need to keep the charger connected, or put a switch/relay in series with the resistor- otherwise the battery only lasts a couple of days.
I've installed my S2 9.7 LTE as a replacement for my car's stereo and its going pretty great so far.
Are you using a (specific) USB hub for all these cables / adapters to connect to you tab 2?

Using as my car stereo is the reason I bought this. What deck are you using. What apps to use for driving, that sorta thing. I'm kinda new to exploring the simplest way to integrate this. I have a magnetic mount so I just throw it on my dash and drive. So far so good but I know it can be better.

There is also adapter called STS-2UE. It's a hub that has 2 x USB ports, Ethernet connection, and it charges the tablet and peripherals in the same time while accessing ethernet and USBs data. It cost around $90 or $100 bucks. On their website lavalink.com you can find a list of supported Samsung tablets. They are a Silver Samsung Partner, plus using this board won't wave your warranty because it doesn't require rooting the tablet. Cheers
