[Q] USB OTG *AND* charging at the same time.

Hello,
Can you have USB OTG and phone charging at the same time? Or even better: HDMI + USB OTG + charging? Without power the phone discharges fast, not to mention - with HDMI out connected I won't be able to connect external HD with movies... Oh, bother...
Or is there some magic do-it-all dongle?

I need it too .
I hate some cable in my bag. One Cable for all is great

USB OTG does not support charging as it has to supply current to the external device.
MHL (HDMI output) does.

Dude, I really hope I'm not misunderstanding, but what is the problem to which 'USB OTG and charging at the same time' is the solution?
Surely you pop your USB stick in, transfer the file and then... stick the charger/HDMI cable back in... and stream wirelessly/over your network?
What were you hoping to achieve? There are several options...

Just taking a guess... maybe he wants to use keyboard and mouse etc with his phone, desktop style

Or maybe I just want to play anything from my 1TB HD WITHOUT deciding what should I copy to my phone (which is a waste of time...)

I wanted to do the same thing but it isn't possible . I do however stream from my nas if I don't want to copy stuff to the phone.

Technically, the USB-OTG standard includes provisions for handling this.
There are several occasions where you would want to plug an accessory into a USB-OTG port and still be able to hold the state-of-charge in the host device.
The specific document: Battery Charging Specification, rev 1.2
ACA subsection (Accessory Charger Adapter)
The ID_OTG pin acts as an input in this mode of operating, indicating whether or not the host is allowed to charge.
Figure 6-6 shows the typical architecture.

Sounds promising. I will look into that! Thanx.

Any news on this?? :fingers-crossed:

so can we use otg and mhl at the same time without charging

Yes, this is pretty much possible. I have implemented the aforementioned OTG ACA support and got it to CyanogenMod9 upstream. Anything which uses the same kernel (or, if you can cherry-pick changes and compile your own kernels), could use that too. Changeset URL: _ttp://review.cyanogenmod.com/#/c/15850/
You need to use a regular USB OTG cable, but place a 36 KOhm resistor between ID pin and GND, then you should connect GND and Vdd to some power source. I used an MHL adapter which I had no use for, as it had two of three connectors I needed. This setup allows me to watch movies from 2.5" notebook hard drive while simultaneously charging my phone if I plug in a 2A-rated adapter. Note that it's impossible to use 650mA charging rate due to chip restrictions (USB HC is too stupid to understand the direction of current flow, and it reports an over-current condition); you have to settle on 450mA.
If you don't know how to solder, or if you use something else than CyanogenMod9 and cannot compile your own kernels, you are out of luck.
I have tried to find an existing USB OTG ACA dongle, but I was not able to find any. If you will be more lucky than me, you can just use it--my patch is compliant with USB specification and will support any compatible dongle.

It's possible.
You need cable y usb. I did it myself.

Duh, I read right past this post... 36KOhm on ID <<< got it, now to experiment!

wow!
it would be amazing if such a device existed!

Hello,
I'm new to this forum as i didn't need it yet but now I have a question.
I know this thread is kind of old and I'm not sure if there are still (m)any people using a GT-I9100... though it would be interesting if anyone found a solution on this topic.
I read several threads where people were discussion if charging and OTG is possible at the same time but no one could verify a specific resistor. Actually i tried a resistor valued 124k between GND and ID but it didn't work. I also read about 36k and other values but nothing verified. Could take a while to try several resistors but i really no one knows a solution i'd try this
So just so sum up, i don't need "MHL and charging" or "audio out and charging". The mode i'm looking for is "OTG and charging".
My Goal: a Docking Station with mouse, keyboard, flash drive(s) and charging to remote control my computer with a software like splashtop.
Hopefully anyone has useful information on this, thanks a lot for any kind of support

Thanks for your answer!
Today i made my 36k cable, this weekend i should have some time for the kernel patch - hopefully
I still have some questions about the kernel as i didn't use any custom ROMs etc on my phone. All I have is a "standard" root kernel without any further changes but root. Need some hours to read into this. What i didn't understand: Do I have to use a specific CM9 or can i use any CM9 (or maybe CM10 or any other CM past 9)?
I wasn't able to get the link working "_ttp://review.cyanogenmod.com/#/c/15850/" when replacing "_" with "h". What can I find on that page?

Charging and using usb hdd - possible?

Hi everybody
I'm just about to mount my carholder, and was wondering if it's possible somehow to charge my tab, and use an usb hdd at the same time?
I'll be using the tab for the children to watch movies, at it could be great to do it that way?
Thanks

The trick would be to find/DIY a powered USB hub that sends power upstream to the host device as well. You'll need a powered USB hub anyways for the HDD, power would come from the cigarette lighter.
It's risky, but maybe someone could take a non-powered USB hub and just inject more power into it. I've got an old USB hub that has two connectors on the host side. One for power+data and another one for just extra power ... what would happen if I hooked up the second power-only connector to something like the Samsung charger. Probably just fry the USB hub with too much current.
Oh, and if you want the Tab to charge with data you'll need a Pershoot Kernel ROM with Any USB Charge enabled on it ...

You cannot fry anything as long as the voltage remains around 5V. The current drain (Amps) ist always limited by the device itself. You could hook up a power supply that is capable of 5V at 100A without danger to the devices.
However I doubt that any USB hub would send power upstream as this could indeed fry a device that is not made to accept current upstream like a normal PC for example. Also I think that the tab would not accept upstream current while in USB host mode since this mode normaly requires downstream current from the tab to the devices. So I don't think pershoots kernel would help.

Edit:
I just found the thread about building your own cables. Click
"USB Host with power" is what you are looking for. Although I doubt that there is an aftermarket solution for this. You will have to solder the required cable yourself most probably.

can be done if you mod the dock...
Look at my post on the make your own cables thread...
Usb host and charge at same time...yeah baby!

USB host cable for $5 on Amazon with Prime (works)

So, this works:
http://www.amazon.com/gp/product/B005FUNYSA/ref=oh_o00_s00_i00_details
However, it doesn't work for everything. A mouse works, but a USB Flash Drive doesn't seem to work, nor does another USB device that does work on the Acer A500 Android tablet I have.
So... Yeah. Just thought you guys would wanna know. I'll look into more devices. I know Honeycomb supported all kinds of USB devices (hub, flash drive, mouse, keyboard) so I'm a little surprised the flash drive didn't work. I'll let you know if I find anything else out. Might just be a driver issue we can work out with custom ROMS. Obviously the communications is working since the mouse works. It could be a power draw issue. I have a USB power meter and the mouse draws 20ma. The flash drive that doesn't work draws 60ma.
-Taylor
UPDATE: Works great with a device we are developing at work (basically a USB hub and FTDI chip combo board if that means anything to ya). It draws about 62ma, so the flash drive issue must not be due to power draw.
UPDATE 2: Rooted users can easily mount flash drives using the app StickMount in the market - its very clean and works well! Thanks to user [esoomenona] for the suggestion.

Actually it looks like no. One of the reviews points out its not a USB OTG (On the go) adapter. USB On the go is a USB port that can act either as a device (plug it into your computer) or as a host (plug in a mouse, etc). In order to tell the phone which mode to be in, USB OTG connectors need to have one of the pins hooked up to ground. Unfortunately not all of these adapters do (I have no idea what they're good for if they don't) and it looks like that one doesn't. But someone linked to the one on DealExtreme that might work.

Shoot, I paid a little over four bucks for that same one from the same company, on Newegg. I should've looked at Amazon as well. Oh well...

Okay, so I received the cable I stated above, and tried to plug in a microSD card via USB adapter, and it didn't work. After a bit of googling, I've come to think of two options for why it doesn't:
1. The cable doesn't work
2. The OS doesn't seem to mount them automatically. I found an app called StickMount on the Market, but it requires root, and I haven't rooted yet.
Anyone know anything about this?

Well I mentioned in the first post that USB flash drives don't work. A card reader is going to have the same issue, as they're basically the same. I think its related to the phone not having its own microSD card, and so it lacks the drivers to mount storage properly. Which still seems silly to me if the device has USB host support, they should include those things!
Plug in a mouse. If a mouse works, the cable is fine.

I honestly think this is going to be it...because of internal storage it doesn't come with the native ability to detect external storage. I'd imagine that app would allow it or that it'll get pushed out as an update down the road...maybe a MOD will get made too if it takes too long.
Either way, when mine comes *crosses fingers for tomorrow* I'll be rooting and post back the results.

Oh damn, StickMount works! Plug in a USB drive and stickmount will pop up asking to run. Then it mounts the drive and my file browser sees it. Then you unmount the drive before unplugging. Wish it was native but this is pretty damn simple. Thanks for finding it!
I was a bit skeptical since the USB drive doesn't even light up when you first plug it in, but once you run stickmount its all good!
Go ahead and root that thing! Just note rooting will erase the phone, so back up first!

I had a Micro USB to USB female for my Nook Color for UBS host. Tried it. Worked like a charm. It even drew enough to power a hub, the keyboard, and the mouse. I was shocked. Im going to but a splitter and use a MHL out to HDMI for 1080 goodness.
Got mine on Amazon for $1.46. Works well (I just wish it was a cable and not a plug though(.

I'll have to see how this works out, ordered the cable.
I have an externally powered USB hub that I can plug into the USB OTG cable.

This is great, I've been looking for these cables. Thanks!
Edit: Does anyone have any idea if you can use an MHL adapter for HDMI at the same time as one of these? I see that some MHL adapters have charging ports, but I don't know if they support data.

Using MHL through a splitter won't work based on how MHL works. You either get USB or MHL. MHL does not use USB-compatible signaling.

Alright, I typed this with a mouse and it's slow, but cool. Guess it's time to root. See you on the other side.

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
http://rootzwiki.com/topic/30615-can-you-charge-usb-host-mode-simultaneously/
Have fun!
10/09/12:
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 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:

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.

get a MHL cable and if your digitizer still works, you should be able to navigate thru the menus and be able to bluetooth or wifi all your data off of it. if your digitizer is broken, use the MHL and a OTG cable for mouse/keyboard control

Thanks so much. Is the MHL Micro USB Male to HDMI Female Adapter Cable for Android Smartphone and Tablet the correct one to purchase?

no problem man

those are the cables, and yep, youre correct. the list in the link has everything from a hub style connector (should need something that heavy duty) to the samsung branded one and everything in between. Remember that if you buy one that isnt the samsung one, then compatibility issues may arise. You could just buy it, use it (gingerly and carefully) then return it. Kinda shady, i know, but yeah.

I've purchased the cable and still nothing. It came with a micro usb. I'm not sure if I'm connecting it correctly but I am getting nothing on screen. Can you please help me connect it properly. All I want to do is turn on smart switch so I can transfer my info. :crying::crying:

take a phone charger brick, plug the usb into it and the other end into the mhl adapter. Plug the usb type c into the phone and an hdmi cable to the mhl adapter and tv. MHL adapters need power to work
