Title says it all, has anyone tried this?
From what I've read (and the other threads on this topic) - no it can't be done.
It can't be done my friend
I got it to work

I used the following and plugged into my TV usb port and had ethernet (verfied with WIFI shut off) and it was charging.
USB 2.0 Ethernet adapter - <amazon.com/gp/product/B003VSTDFG>
OTG with power - <amazon.com/gp/product/B00C452XFO/>
Yup, this now works great for me too! :good:
I bought the Ethernet adapter Nvidia Recommends (same as browncoatdave's)
http://www.amazon.com/Plugable-Gigabit-Ethernet-Chromebook-Specific/dp/B003VSTDFG
And just whatever Y cable could find that didn't look uber cheap.

Did you plug all the devices in a particular order? I noticed that if I plug in my charger AFTER I plug in the OTG cable into the shield, then it is not charging. But when I plug in the charger into the OTG cable and then plug it into shield, it is charging.
Is your hub powered? What exact model is it? I am asking because I have very similar setup to yours but the shield does not detect USB devices connected to the hub - it's this one: http: // esperanza . pl/esperanza-usb-2-0-hub-4-porty-ea116,182,437.html
I can connect one usb device directly to OTG cable and it works, but when I connect a hub, it no longer works.
There is a cheap way to do this if you have the soldering skills, and are willing to try it.
Get a cheap USB "Travel" hub.
Open it up, and replace the Upstream USB cable with an OTG cable (A scrap Micro-USB cable may or may not work. The connector must be Properly wired for OTG).
Remove the main power diode in the USB hub, and solder jumper the 2 pads where it was. A Multimeter in continuity mode can help you find the right component, but it takes some experience. There usually is not much in a cheap travel hub, so I can usually find them just by looking, but like I say, only try this if you have the experience, and you know what you are looking for.
Power the hub through it's 5V power jack (if it has one), or you can add a power only micro-USB socket. (Only connect the (+) and (-) power pins, do not connect the data lines. Connect it to any one of the Full size USB port's power pins. Observe polarity.)
Voila! You now have 4 Full size USB ports, it will charge your device, and provide power (Up to the rated power of the AC adapter) for your USB devices.
I did this years ago in the Nokia 770 days. It was one of the first consumer devices that supported USB OTG. Article still exists here:
http://www.linuxslate.org/N770DockingStation.html (Scroll down to the "Electronic Components" Section)
Would this work?
Would this: SODIAL(R) Micro USB Host OTG Cable with Micro USB Power plus this: Anker® Unibody 3-Port USB 3.0 and Ethernet Hub
Give me the ability to charge tablet, use Ethernet and additionally connect USB mouse and keyboard, and possibly charge Nvidia Game Controller?
Or would it just be a waste of time and money
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.

Nice setup! :good: That's exactly what i want to do. I can connect a mouse and thumb drive but no power. I was trying to work-out how to use a switch or relay or something to switch between otg and power but i haven't came up with anything yet.

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 !
Sent from my GT-I9505 using xda app-developers app
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:

Hi, ive registered with this forum to ask for some information on the Amazon Firestick. I am thinking of buying a fully loaded stick from Ebay in the UK. My main question is i have a UMC 40 inch TV with a usb and Hdmi port but its not a smart tv. Will the Firestick work or do i need a smart tv. Any help would be appreciated Thanks
No SmartTV needed, only HDMI is mandatory of course. USB power can (or better should) be done with the USB power supply of the stick, so also USB must not be used from the TV and can be left free for other devices which need to be connected directly to the TV.

= Plug the FireTV Stick into the wall for power, don't plug it into a USB port on your TV for power.
I use my tv's USB port for power with no ill effects. We don't use the USB port for anything else, and it means we don't have to have yet another device plugged into the wall. It does mean that the Fire TV boots up every time the TV turns on, but it boots fast enough that this has not been a distraction.

It might work fine for you and other people, but in general, TV USB ports are not reliable as a power source. That might vary from brand to brand, however, it should be noted that an inconsistent power supply or one that doesn't meet the manufacturer's specifications can be bad for the unit over time.
I tried it with other devices. Its a nice way to eliminate wires but I got random reboots and freezes. Never tried it with stick but some people report it works fine.
In general it might work with regular USB power from a TV USB port but I personally had problems with WIFI. It seemed that the stick did switch down WIFI speed (and probably slows down the CPU) when the power is restricted to a TV USB port but does run on full speed with the external power supply. Also those decoding problems during video streaming which is often reported here may come from insufficient power.
A USB port is specified to deliver 0.5A at 5V so thats only 2.5W power which is guaranteed and it´s only mandatory for devices like TV sets to deliver more power. So it makes sense that Amazon did deliver an external power supply knowing the power consumption of their stick My hint would be to check first with external power supply if the stick is running fine and how is streaming working with speed and quality than it is still possible to try only with the TV USB power and it can be compared if there are no negative perfomance issues. But I bet most people will attach the external power again.
Not sure if this is a question for this forum but feel there will be a fair few experts on here who may know the answer.
Will a 4K firestick work by plugging it directly into a 2.1a 5v wall socket outlet with USB port?
Looking to buy a LAP 1-Gang SP 13A Switched Socket + 2.1A 2-Outlet USB From Screwfix
From what I’ve read, people have been powering their firesticks on TV USB ports with some success. Some have reported that less than 1 amp power on older or smaller TV’s would under power it. My concern with the wall socket may be too much power?

you will be fine using that. The amp rating is for the load it can handle. for example if you put a hub on it, you could power 4 devices that require .5 amps each. I believe the firestick 4k requires 1.5 amps (it may work on less but could cause issues)
Great. I was concerned the socket would be too much for it and perhaps overheat it or something and I plan on not using the plug Firestick plug (brick) which is fused
All Fire TV Sticks have a power adapter capable of delivering 1 amp of electricity. Of course, that doesn't imply a Fire TV Stick needs that much power to function, but it can theoretically draw that much power from the supplied power adapter.
So you may take advantage of that. Because if you put a hub on it, you can power four devices that each require 0.5 amp. In addition, this firestick needs a 1.5 amp power supply.
Greetings!
Hope this is the right place to post this. I've installed ElementalX kernel in hopes of charging my Nexus 7 (2013 - Android 6.0.1) while having USB devices plugged in (charge during or plugged in after). My ultimate goal is to have a USB accessory permanently plugged in (mouse, SD, whatever) and be able to plug in my charging cable whenever needed without unplugging the OTG cable.
When I was on stock, any USB device plugged in functioned normally (as expected). After going over to ElementalX, the USB port only recognizes charging and not devices, even if I'm not using charging and plug a mouse or thumbdrive directly in, it reads nothing anymore. I've tried plugging the charge cable in before and after plugging in the devices, nothing.
I've tried several OTG cables and adapters, USB devices, tried wireless charging + device, still the same issue persists. If I disable the OTG feature, the USB port works again for devices (just not simultaneously with charge of course).
I've tried various builds of ElementalX, Kangaroo, Glitch, anything that has Nexus 7 OTG+Charging support (haven't had luck installing Timur kernel without crashing). Not sure what I am doing wrong or if there is something I am missing.
Any help would be appreciated.

Hi, you write about "several" tested OTG cables and adapters but "OTG + charge" requires a specific Y-OTG cable with extra power connector. Do you really have so many of them? The only one I have and EX kernel with "OTG + charge" mode work flawlessly for me. Note on the attachments :
- "OTG + charge": ENABLED
- the charging icon: ON
- OTG mouse cursor: YES (internal screenshot does not capture cursors, hence a pic)
In case it has something to do with your system configuration, please do RESTOCK + addons where "Install ElementalX kernel?": YES and then select "OTG + charge" mode.

Thanks for the reply,
I did the full RESTOCK with all the addons as you suggested, I enabled the OTG+Charge again and these are my test results:
"OTG+Charge = enabled" + Y-OTG + Mouse = Mouse does not work.
"OTG+Charge = disabled" + Y-OTG + Mouse = Mouse works.
---
"OTG+Charge = enabled" + Y-OTG + Charger = Charger works.
"OTG+Charge = disabled" + Y-OTG + Charger = Charger does not work.
---
"OTG+Charge = enabled" + Y-OTG + Mouse + Charger = Mouse and charger work! However, as soon as I unplug the charger, the mouse stops working. I also tried with a thumbdrive and it has the same results.
---
I do have 3 OTG Y cables and an adapter that I have purchased from user recommendations in the ElementalX thread and from Reddit and they all yield the similar results.
I'm going to investigate other cables, maybe I just had bad luck with the ones I got? If you have had success with a particular cable, mind dropping a link?

I made the cable. I think all your Y-OTG cables, apart from power, also Y-split data lines which is counter-productive. If you use a PC USB port for power then the data lines will interfere with OTG mouse, flash drive, etc. If you use a smart QC charger for OTG power, the data lanes are active and OTG will not work. Even some dumb chargers would ruin OTG because they may short out both data lines to signal high charge current capability this way.
Here is a simple test for your Y-OTG cable with a mouse. Disconnect it from N7 and disregarding the micro-USB, connect the USB-A male into a PC port. If the mouse works it means data lines are Y-split too and you need a workaround. Find a non-QC charger, make a USB data-separating adapter or mod one of the Y-OTG cables by cutting off both data lines from the USB-A male plug.
The mod is really trivial, cut off the white and green cables...
EDIT to your edit...
""OTG+Charge = enabled" + Y-OTG + Mouse + Charger = Mouse and charger work! However, as soon as I unplug the charger, the mouse stops working. I also tried with a thumbdrive and it has the same results."
Well, this is the expected behavior, so there was nothing wrong all along

Is it expected that as soon as I unplug power from the OTG, it all disconnects though? Just seems contrary to everything I've seen online. I can plug in and mouse and it works, plug in power after and works. Unplug power and its all offline and I have to reset for it to work again.
I tested the cable on PC, doesn't move the mouse. I checked the power line and there is only a positive and negative line inside, no data lines.
