Hi,
My HTC J One ([email protected]) got wet and Wifi dead. I want use it as desktop computer.
OTG for KB,mouse and USB-LAN, MHL for display. And the phone must be always powered.
(I need to find a ROM that support LAN and compile kernel module for my USB-LAN.)
So is that possible to use OTG and MHL at same time while charging the phone?
No ideas?
When I tested this, I couldn't even charge+OTG at the same time. I'm not sure whether that's a kernel restriction or hardware.

Samsung talked about usb 2 hdmi cable and think if its real it use some usb video card supported by phone(because of physic material imcompatibily of hdmi nd usb)
May there is a way to dev a tool or hack to get it works...
Aah!! Finally somebody like minded!!
I had been scouring forums for something like this. USB OTG would be an excellent add on to this phone. If not OTG, at least host would be an excellent idea.
No idea whether the existing USB Host driver for Nexus one would work on this one.
The processor on SGS already supports USB Host (not sure about OTG though). This has been pointed out in their press release - w w w .samsung.com/global/business/semiconductor/newsView.do?news_id=1043
I am just wondering - should we request Samsung themselves via mass petition to open up this feature on SGS?
some USB devices might be compatible, like the 100/1000 Mbps USB to RJ45 plugs
those same ones works in Windows Mobile it should work as well for Android, however a driver will be required.
mouse and keyboard support should work out of the box
external USB keys for storage, or even USB mass storage devices should work out of the box as well.
usb audio... hmm... not sure what else at the moment
Hi AllGamer
Thanks for the reply. So how exactly do we get this going on SGS?
I am much more interested in having USB HDD support on SGS (hopefully without an ext power source - am I asking for too much? ).
Are you suggesting that the N1 fix should work here also? Can somebody help us with a "How To" to enable this on SGS?
Cheers!!

you can plug in any USB mass storage devices (USB hard drives) and it should work.
However, you might not get enough power from the usb port, you'll still need need power cord for your external usb hard drive.
I know on my HTC windows phones works like that, it should be the same for Android.
I'll try that when i get a chance.
you just a need a USB female to a mini USB male cable
yep!! you are right about power!!! I am trying to get a cable - hopefully in couple of weeks should have this.
but I am wondering if all this would work without proper drivers in it. Would SGS have USB HDD drivers in it already?

I can see one problem, You will only be able to use Fat32 drives unless someone compiles NTFS / HFS+ into the kernel. Ext3/4 is already done so I don't see many problems. What I recommend you do is get some sort of adaptor for Female USB > Micro USB and test it out with a flash stick or you can hack one .
Yeah - I understand the difficulties of having NTFS support outside the MS world.
I didnt know that ext3/4 were already a part of the kernel!! Is this by default available in all Android kernels?
For USB Host cable - I am guessing that this one can be used - http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250671106072 (same as what Sven used for N1 USB Host capabilities).
But I seriously doubt plug and play would work (that would be too much of an expectation! )
Does any body have that cable here, who can check out if SGS does actually work in USB Host/OTG mode?
Sven has try with a Galaxy another Host Driver

Hm what can we do with these files?
However, any news about this?
Maybe, we could ask some Galaxy S kernel developers about this.
Not sure if this has already been discussed/discovered, but will it be possible to use the new Nexus dock "and" an OTG cable at the same time? It seems feasible given that the dock charges the device using the pin connectors which frees up the USB port.
One possible problem is that the dock also acts as a passthrough for data/audio so there may be a problem with the tablet trying to reconcile both sources trying to have simultaneous access.
I ask because it would be nice to be able to charge my Nexus 7 and utilize an OTG cable (for storage drives and game controllers) at the same time. I know there is an OTG Y-cable solution, but that involves rooting the tablet.
Has anyone already explored the possibilities of this combination?

I read somewhere else that while docked, the device doesn't react to an OTG cable. This is just what I've heard, haven't seen it confirmed.
This guy did something similar, and the results are evident: Dock point is useless! Charge and OTG can not be carried out simultaneously!
Would be nice to know, if Timurs kernel, which allows charging and multiple USB would solve this. Have no dock, so I can not check. What I would like to have is something like the magnetic pogo charger which is annonced for Nexus 10.
Hello!
Today I (Finally) received my USB OTG Y cable! I have the Samsung Galaxy S3 4G (I9305) and i bought the cable because the ebay site said it was for s3. I was really happy when i got it and plugged my usb memory stick into it. It all worked good. Then I plugged in the charger (to the female micro usb) and it didnt start charging. I wasn't happy anymore. Then i started to researh a little. I found out that my phone doesnt support USB host mode and charging at the same time ( ). So im just asking, is there a way to make my phone charge when i use the OTG cable without any hardware modifying? Can I just likes install a custom kernel that supports OTg charging? Or just make my phone think its docced when i use that cable (I thought that may work)?
Btw im running android 4.4.4 stock rom and stock kernel. Thanks for any help.
And here is a picture of the cable. Down there ⬇
Nexus 7 (2013) with OTG and charging at the same time.
NO MODE NEEDED
[Little Intro]
I bought a Nexus 7 (2013) to use as a personal computer.
I admit, I've ****ed up the device a few times experimenting with kernels and stuff.
The thing is, you just need it rooted to use USB reading. Then you think: ok, I'm using USB and external HDs, I'm using mouse and keyboard, a external all-in-one Card Reader, and even a device that communicates with an XBox Wireless controller, but using as a computer the battery will go quickly.
I've tried two Android Cyanogen's distros and ****ed up the device 6 times. So I kept the default kernel rooted, plugged into the USB Hub device and said: well, **** off.
The thing is, when using the device I've noticed it was charging, but not saying it was charging.
[Explanation]
With my little technical knowledge of electronics I can explain what happens here.
The kernel does not support the use of OTG and charges at the same time: that is theoretical, saying that in software is not the same that measuring that.
So, what if the system charges but it just do not know?
Even if the both sides have the same potencial difference (I guess that is called voltage in english, a term disregarded in my born language, sorry about my english by the way), what if one side is providing a larger current? In theory the other side will charge, if it is a battery.
So, what actually happens is that the Nexus 7 charges, but the system level software, that, in theory, do not permit that, just do not show what is actually happening.
Obs.: I've tested the USB-Hub into my computer and it accuses overvoltage, and then when plugged to my computer I need to turn off the external power of the gadget. So, it is probably because of the specific gadget I'm using.
[Little things]
That could, may, just be possible with some specific equipment, so I will post the exactly equipment I'm using, and how I'm using it.
I ask you guys just try without the power loop I'm using to know if it is necessary, and the Nexus 9 guys to test if the same happen with it.
[The equipment]
My USB-Hub: www.dx.com/p/7-ports-powered-usb-hub-678
My OTG cable: www.dx.com/p/micro-usb-male-to-usb-female-w-usb-male-otg-cable-black-170927
[How do I connect it]
I connect the OTG cable by the male micro-USB into the tablet, loop the power with the male-USB into any USB port of the hub and connect the female-USB into the default hub main port - that one that is not the default USB-like format.
I power the USB hub and that's it. I'm using a Logitech dual transceiver with mouse and keyboard, the default microsoft XBox USB gadget, a generic all-in-one card reader and a 4GB Seagate external HD plugged into the hub.
[A final little thing]
Yes, it does not charge quickly, and yes, sometimes the battery level will be consumed a little bit. But it works well generally, without any mode needed.
It seem that is not the same as in powering mode. I'm thinking in to build an image that permits to choose between on or off in the USB out port. Can someone guarantee me that this is what the Cyanogen kernels do?
Kernel mode differences
Just to be clear, the "original" kernel mode can't know that it is charging and accessing the OTG at the same time, even doing it.
Maybe, and just maybe, the other kernel modes just let the kernel know it, having no difference to the original kernel. That's a big maybe, but a possible one.
I'd expect someone to confirm that the kernel modes "cut off" the voltage, and because of that may charge faster. Someone?
Hello guys,
I would like to use my XZ2 with USB Hub to power mouse, keyboard, flash etc. But I worry about it discharging quickly while playing for example. Does XZ2 support OTG and charging at the same time?
I bought an OTG charching cable from china recently but it does not seem to work, it does not charge even without OTG device connected. So I wanted to ask if any of you have any experience with this. I read that some devices support it, but its dependant on the kernel. My samsung tablet does.
One thing that comes to my mind is, is it possible to OTG and wireless charge at the same time?
And lastly, does XZ2 support USB-C to HDMI, I think that I saw post here recently, but I am not entirely sure.
Thank you for any responce in Advance.

HDMI is not supported and your dock needs an own power supply or your phone will tell you, that the hub needs too much power.
