Just want to know for something like, connect a external storage and the other usb to charge the phone or something else and still have the other one to charge the phone.
Thanks

It looks like it works! Both the phone and my 64GB flash drive are being powered via a USB charger connected to a Y-cable. As far as I can tell, the phone battery isn't being charged and may still be draining a bit--this may depend on the current delivered by the USB charger. But I've been playing music for hours from an attached USB flash drive with my screen on and the battery level is still sitting at 98%.
I've attached ZIP files with a boot image containing the kernel. The yakju boot image was created by replacing the stock kernel in a Nandroid boot image obtained from the Galaxy Nexus described in my sig. The other boot images were created from the boot image included with the Google factory ROM. I can't test these, so use with caution. NOTE!!! Make sure you do a Nandroid backup of your phone before trying out the attached boot images. Things can go wrong and you want to be able to recover.
This was posted earlier in the thread, but credits for the kernel code tweak, along with details, go to the contributor to this thread

Have fun!

I've added two more ZIP files. These contain boot images with the code modded such that the phone battery is charged when using the Y-cable. NOTE: The phone will think it is being charged any time a USB OTG cable is connected. I haven't figured out a way around this yet. This doesn't really hurt anything, except if you have your phone set to stay on when charging, you could end up running down your battery! Important safety tip.
10/15/12:
I've replaced the previous ZIP files with two new ones. These contain boot images for takju and yakju JRO03C/4.1.1 that provide USB OTG+charging, with the added benefit that you can still use a standard USB OTG cable to connect an external device. As in the stock kernel, the phone will provide power for the external device. In other words, the new kernel in the ZIP archives auto-detects if there is a charger attached via a y-cable and uses it to power the external device and charge the phone, if it's found.
I've also fixed the problem where the phone would show a charging icon in the notification bar if a USB OTG cable was attached without any external device connected to it.
NOTE: THESE ZIP FILES ARE NOT MEANT TO BE FLASHED TO YOUR PHONE. These files contain a file called boot.img that can be flashed to your rooted phone from your computer via ADB with the commands
fastboot flash boot /path/to/<boot>.img
fastboot reboot
You can learn more about using fastboot at http://wiki.cyanogenmod.org/wiki/Fastboot.

Version V4 is replacing V3. This new version fixes the bug where detaching external power from the USB OTG y-cable or USB hub wasn't detected by the phone. Now, when power is detached, the phone switches to battery power, including supplying battery power to any attached USB devices.
Note that the reverse is not true. If you connect external power when the phone and external USB devices are being powered by battery, the phone will continue to use battery power. The external power is not detected. When in doubt, disconnect and reconnect the USB OTG cable to cause the phone to recognize what's attached.

I believe he is making a reference to your op
I don't understand what op is asking.
Sent from my Galaxy Nexus using xda app-developers app
I think he is wanting to somehow daisy chain the devices having power from the first one provide enough charge current for the last one. Least that is what im thinking he said i dunno though
Ok let me explain it a bit better. Lets say I have a flash drive (external storage, external hard drive, whatever you want to call it) I connect it to my phone with a usb to micro usb adapter. Now I have my ONLY micro usb connector in use, but after a while I'm running out of battery so I want to charge my phone BUT I can't since I can't remove my flash drive (because I'm using it).
Now I'm asking for an adapter or something that can let me connect my flash drive and still be able to charge my phone. like a 2 usb to 1 usb adapter for PC. Or like the adapter to connect 2 headphones in one headphone port.
I hope it's clear enough now. :laugh:
http://www.monoprice.com/mobile/Pro...Id=103&categoryId=10303&subCategoryId=1030303
Connect that to a powered hub, plug flash drive into one of the hub ports. That should work, though i don't use usb otg, so i couldn't say for sure.

Unfortunately, the answer is no. I've tried several ways to get this to work, with no success. I routinely mount a flash drive using a USB OTG cable and the Stickmount app in order to listen to my music collection. It works great, but USB OTG drains the phone battery rather quickly.
I even cut out a notch on my desktop dock so I could attach the flash drive while trying to charge the phone via the dock's pogo pins. Here's a thread discussing this:
http://forum.xda-developers.com/showthread.php?t=1651757
The USB standard does provide for a method of charging while using USB OTG via a device called an Accessory Charger Adapter. But I haven't found such a device available anywhere.
Sorry to be the bearer of bad news. If you do happen to find another solution, do let us know.
I don't think I have the bits needed to try it, but looking through the spec, I think you can simulate the requirements for the ACA.
Connect a 124K resistor from ID to GND on the micro side. That should tell the OTG host (the phone) to go to Charge/Host mode allowing the B device (memory stick etc) to work AND allowing the phone to charge... You will need to provide a decent 5V power connection. You need to power both the phone and the accessory device from this.

Ok I understand the resistor and where to connect it, but where I will connect the power source? if the memory stick is using the micro usb port?

Hi,
I saw a plug (green colored) quiet some time ago on xda that would attach to MicroUSB on the phone and on the back end was another MicroUSB for charging along with USB slot, card reader. It used to be under or around $10.
Does anyone have a plug like that, i am thinking of using it with my GNex.
Thanks,
It's called usb OTG.

I was wrong. I ordered an OTG Y-cable and it arrived today. I plugged it into power first. Then I plugged it into the phone and it started charging. Third, I plugged in a USB stick and it mounted (using the help of the Stickmount app).
I then watched a movie from the USB stick and watch the charge level go up 4 percent while watching.
Awesome!
I am on Franco's kernel but I don't think that matters as long as you are rooted and have Stickmount installed.
Edit: This is the cable:

I have bought that but only works the usb 2.0, i cant charge the phone. Sorry but i cant post the link of the product, here is a picture of them.
Sry for my english.
Make sure you have a 'charge only' lead to the charger (Shows as 'AC connected' not 'USB Connected') or you'll find you won't have enough power to do everything.

Yes, i tried but i cant charge. I tried with other phone and works but dont have otg support.
The problem with OTG and simultanous charging is that you'll probably need a custom kernel supporting this.
Because if you use OTG (or a data cable respectively), the phone will only charge with 500 mA max. - this might not be enough to charge your phone while using power-consuming apps (navigation, games,...). If you want the phone to charge faster/draw more current, you'll need to short-circuit the data leads - but then you can't use OTG/data. Tricky...

I think that is not the reason because if i try to charge only didn't work, i think the charging cable is not compatible with moto g like some chargers specific for some patents.
If someone knows a cable like that to charge and use usb stick or something compatible with moto g I would appreciate.
The cable is probably working, but the kernel is not supporting it. If you use a USB y-cable, it will power a plugged-in USB stick / device, but not your Moto G. You will need a kernel or tomorrow supporting simultaneous data & charging. Have a look in the Nexus 7 sections, there you'll find more information about this.

Hi all, I have the Nexus 5 and wish to connect the TP-LINK TL-WN722N USB Wifi Adaptor but I am having no success, I purchased a Y Cable to connect it to my phone but when i plug it in nothing happens on screen or no light comes on the Wifi Adaptor, I plugged my charging cable into the other end of the Y Cable but it doesn't charge the phone, I thought my cable must be faulty but i've now used 3 more and all with the same outcome. Is there something i need to do to my phone to get this to work? The port on the phone works fine as it connects to my computer and charges perfectly when i just use a normal cable. If you can help me it would be greatly appreciated.

from doin this on my nexus 7 to use nethunter kali with the wifi adaptor i would say you need a rom and kernel that support usb-charge and host. stock android doesnt support wifi adaptors . u can access and use the adaptor in a linux kali but you cant use it in stock android to say browse the web instead of using on-board wifi chip/card.
edit : Also most of the y-cables you can buy from e-bay dont actually route power to the phone/tablet and to the attached device, the power only goes to phone, i had to make my own charge/host usb cable with a soldering iron and heatshrink tubing. this cable charges the phone/tablet and provides steady power to the attached devices (wifi adaptor, mouse,keyboard,hard-drive) the ones i mention previously from e-bay dont provide enough juice to power the adaptor.
You need a custom kernel with module loading, root and your wifi adaptor´s module, altough my WN723N and a cheap old ethernet adaptor worked out of the box(chroma rom with elementalx kernel)

hi there, im crazy with this
i got a nexu 7 2013 wifi, as like you I use CM 13 with elementalx installed and otg and charge enable.
i use a Y cable, a hub cable too and any works.
if someone can explain or tell me why.....i need it for my car

Otg splitter and hub is so you can power your tablet and any devices that are connected to the hub .. Ex. Joycon , video grabber , dac ...ect
Timurs kernel is the most reliable but you have to donate to get it ... Elemental is free but sometimes has issues with otg/charge bugs upon wake
You need the ability to enable Fast Charging for the kernel.
Simple USB-OTG won't get you full charge speed.
I know Timur's kernel for 2012 model has a Fast Charge option that is probably also available on the 2013.
And ElementalX kernel *might* be getting that option soon too, if not already.
