Has anyone successfully been able to use an OTG cable with phone? - Samsung Epic 4G Touch

I think this feature is badass and want to use it. Broke my MacBook back in July and don't have the loot to replace it. So, I thought I would use my phone as my computer.....kinda like an experiment to see if I can use it for normal daily uses. Got the MHL cable a few weeks back it rocks.
So I ask if anyone has been able to use the OTG cable with this phone with stock or a custom ROM.
Thanks.

Kernel with USB Host functionality

This is a question to the Developers here on XDA, especially the ones that are developing for the Desire HD.
I would like to point this out http://forum.xda-developers.com/showthread.php?t=694427
Like you readers have already read it's about USB Host functionality on the Nexus One.
On the following link you will find a thread of this being ported to the HTC Desire
http://forum.xda-developers.com/showthread.php?t=702742
The Question is, if there someone who knows how to get this to work on the HTC Desire HD and is willing to do that? It's not a practical functionality but it's sure is cool to have the possibility to connect your external HD, USB Controller, USB Mouse or whatever USB device on your Desire HD.
From my little knowledge i think that the modules need to be implemented in a Kernel, Maybe it would be a nice project for someone who works on Kernels? I don't know how to support the Desire HD with this feature, I hope someone can.
Kind Regards,
Shar!ngaN
I looked at this last night, but without having an adapter, I cannot test it.
I can however build you a kernel with USB Host compiled in tonight when I get home.
Would be nice to know if it will actually work
Send me a PM if you are interested.
Edit: Thanks for those links Interesting reading and info I need.
Edit 2: Adapter ordered.

I've ordered an USB Host adapter around December last year, but it still hasn't arrived. So i actually cannot test it at this stage. However i would like to see that Kernel and would love to test it (As soon as my adapter arrives).
Thanks
Question: Do you only need an adapter to connect normal size USB to mini USB? Will the dhd have enough power/voltage to run a flashstick so you don't need external power?
If i only need an adapter i'm in for testing if it's compatible with CM7
I have an adapter lying around from using it on my N900 that had USB otg/host mode
From the video's i saw of Sven Killig's, that's the man who achieved USB Host functionality on the Nexus One. He powered his USB devices trough a self-powered USB hub.
@Shar!ngaN: As soon as I get my adapter, I will start messing with it.
But as you know with DealExtreme, that can take up to 30 days to arrive.
Yes i'm quite sure you will need an external self-powered hub.
I have already purchased all the equipment i need so i just need to get into the nitty gritty of modifying the phone. I need help on this!!
I have been playing with compiling this functionality into a custom kernel, but I dont know if everything is ok.
Will read up on the other phone's thread to see if I missing something.
@Mr. Blobby: Are you willing to reflash your kernel? This will be a requirement.
Ok that's no problem, and thank you very much,
Yes i am willing to do that, however i have been told it is very risky and you need to know what you are doing when carrying out the process. As a result, i am waiting to find out if someone can help me with it as i know nothing about smartphones and i don't want to end up breaking the phone.
Thanks alot.
I have the adapter and im awaiting the kernel (hope it works with the Telus version)
Flashing the kernel is not risky as long as you backup first. Use Rom manager.

ooo ok thats a relief thanks!!
can someone please tell me what i first need to do? do i first need to root the phone as it is not yet rooted. If so, how do i go about doing it without 'bricking' the phone?
Thanks!!
Bump, any news on this

I'm still waiting too
i've got all the cables and stuff i just need to know how to re-flash kernel and root the phone etc
Anybody got it working allready?
I've gut the stuff to do it but i have no idea how to build the kernels and stuff
will be great to see it on an cm7 kernel
Too bad, still nothing
From the https://github.com/CyanogenMod/android_vendor_cyanogen/blob/gingerbread/CHANGELOG.mkdn, it seems that CyanogenMod has got USB Host included from version 7.1.0.
I am using the JellyBean - Jelly Time ROM and wish to use my DSLR via the USB host feature, but not sure how to do it yet I have the OTG cable(http://cgi.ebay.in/ws/eBayISAPI.dll?ViewItem&item=170844328875).
Any pointers anyone?
CM doesn't have USB host for all devices. In the change log - "Encore: USB host support - Verygreen". That's only for s specific device. If it was listed as 'Common' then it would be for all devices.

need help unrooting.

OK, so recently my epic only wants to charge from certain chargers. The normal charger that came with the epic doesnt work no more, and about 15 other chargers laying around my house for all kinds of different phones will not work either. Ive only found 2 chargers that work. A moto droid one, and some LG one, I want to do a insurance claim but i need to get this unrooted. The problem is: my phone will not connect to the USB when its in off mode so i cant odin or anything like that. i need something i can flash through the phone to unroot. Im on syndicate latest rom on ec05. please help!
If you are going through insurance then you don't need to worry about it. Just flash ReRFS ROM. They may figure it out as a bad USB and fix it for free.

USB Issues...

Hi All,
My SGS2X no longer connects to any PC for anything other than charging.
I've tried everything, trust me. I've come to the conclusion that it is defective and want to return it for a new one. The problem is that I have rooted it and need to undo this before I return it. Telus told me it would need to be sent to Samsung for testing before they will give me a new one, so I need to unroot before I allow this.
Is there any way to unroot without a USB connection to a PC or am I screwed?
Thanks,
Mael
you might want to send it in for repair, to have the USB port replaced
Try using a different wire this same thing happened to me i believe

You might haved tried that tho try another to be safe
Sent from my SGH-T989 using XDA App
every time my phone drops to the floor while plugged in, the first thing i always worry about is the usb port
because of those issues reported above
Tried different cables, same problem.
Same cables work with other devices and other phones...
Phone has never been dropped, plugged in or not, so must be a defect.
Seems like a defect to me and thus covered under warranty, only prob is that it's rooted, voiding the warranty. Hence the question on unrooting, but I don't think it's possible.
I may just put up with it for now... It's a hastle not having access to USB storage, but I can work around that. Once I decide what I want for a second phone (Nexus or Note), I'll buy that, then brick the GS2 and go for warranty replacement then...
Pain in tha a$$, but thems tha breaks...
just ... never mind
i was going to suggest Odin, but then i remembered, sheet no USB, no can't do
the stock rom can't be flashed form CWM on the external sd card? I didn't realize that ODIN was required to put back to stock. Just wanted to clarify this.
Have you tried blowing out your usb port on the phone with some compressed air ???
Had a friend of mine , brand new phone, his USB just stopped, it would charge, but nothing else ... Screwed with it for hours, then he blew it out, and it worked ..
Sometimes your phone just wants a good blow job, just like the rest of us ...
(yeah yeah rude crude and socially unacceptable , but hey still funny) ...
Never thought of that... I'll give it a try...

This thread describes a method for flashing a stock kernel and (somewhat) stock ROM by flashing the files with CWM. You won't need your USB port, I just don't know if the stock ROM linked to in that post, will pass for "stock" on your Telus SGS2X. It may be good enough to pass for a warranty exchange/repair, etc., or there may be a stock Telus ROM floating around that is CWM flashable.
Good Luck..
Have u tried the samsung usb cable that came with your phone? ive found samsung phones to transfer data with the stock cable...everything else just charges the phone....just a suggestion
Sent from my SGH-T989 using xda premium
Tried the compressed air, no effect.
The ROM on the phone is stock, all I've done is root and install CWM.
To al appearances the phone is stock, but for the presence of superuser and CWM.
Tried the original cable, no difference...
Telus told me to go where I bought the phone, so I'm going to try going to BB and raising a stink, see if they will replace it...
By bb u mean bestbuy im sure they will they are awesome with returns well atleast the one by my house i like there no questions asked hahaha

Rooting without being connected to comptuer.

Hello XDA members,
Couple of weeks ago, I plugged my charger and then all of a sudden, smoked started coming out accompanied by a burning smell. I quickly took out the charger and now I am not able to charge my phone. I recently sent it back to Samsung for repair but they could not fix it under warranty and was asked to pay $200. Imo that is way too much considering brand new Galaxy Nexus is around $500 where I am from.
Prior to sending my phone, I unrooted my phone, reverted back to stock rom and now I am wondering if there is a way of rooting my phone without having to be connected to the computer via the USB cable. I want to install a custom rom but is that even possible without having the ability to connect to your computer?
Thanks

You can fix the USB port for a few bucks, i seen people say it cost $10, not really sure as i never came across one, but it should be out there on ebay.
You will be looking for a microUSB board

I am in the same situation as sgs064. I have a Gnex that I need to root, but it will not connect to the PC with the USB cable (strangely, it does still charge via USB). I probably will just fix the microUSB port as Mach 3.2 suggested, but in the meantime it would be nice if there was a way to do it without USB. I realize that it probably is impossible, as efrant indicated, but if anyone has any ideas, I'd be willing to try em out. This is an extra Gnex, not my everyday phone, so im willing to mess around with it a lot more.
Thanks.

[Q] OTG Cable for Sprint LG Optimus G LS970

Hi I am new to this forum and i just purchased and unlocked my Optimus G. Now I'm looking into a OTG cable that may work on this phone as the sprint version, as you all know, does not support Micro SD cards for extra data storage. Now i know they have wireless HDD's that you can carry to store information and Bluetooth keyboards and mice that you can connect to the phone out of the box. But i had External HDD drives that are not wireless and a Wireless keyboard/mouse USB combo all that i would like to run on the phone at a cheap rate. I have read some places that OTG is possibly not capable on this phone. Can anyone verify that this is not possible. Again i am very tech savy and my phone is rooted and unlocked, so if all i need to do is change a kernel or install some files i can definately figure out how to do that. Can anyone clarify this for me and if it is possible put links to cables and tuts on how to do this? i couldn't necessarily find it when i was looking on XDA earlier, and its the only site i really trust for information about my phone.
"USB host", or what is commonly referred to as OTG, is not supported on this device. I'm not sure of the usb controller so I cannot say as to whether or not this is a hardware or software limitation. Either way, I consider this a serious shortcoming, especially on a flagship device.
I was hoping you wouldn't say that. Well if that is the case, can anyone verify if this is not possible because of the software or hardware. If it is because of the software is anyone trying to develop anything for this right now? Thanks again for the verification^

the nexus 4 "doesnt support otg" yet people have modified a kernel to add the feature in. the device does NOT support 5v so you will need to power the hard drive or w/e with external power using a y-cable.
if we have the same usb controller as the nexus 4 then i would assume we'd have to do the exact same thing... custom kernel + y cable for external power. so try and get some kernel devs together and work on on getting that project started for the LS970 device if you really wanna see it happen.

I built in USB host and USB otg support and a art user reported it wasn't working. However I can through up a 3.4 kernel if someone has the cable and power to test it.

If u send me a link to a y cable i will purchase one if that's what's needed. What are the risks to updating to this kernel you mention?....^ somebody on the other thread that was posted here said we have a more complete usb host package than nexus 4. I think he was the thread creator. When i get home ill qoute his post.

That's up to your kernel devs. I outlined everything required for the N4 here: http://forum.xda-developers.com/showpost.php?p=38906771&postcount=2
That said, I once took a look at the kernel files for the Optimus G and it looks like the code for otg/host mode is far more complete than that of the N4. I'm curious if it's able to read the ID pin in its current state..

This is what they had to say on the other forum so far. I don't know any dev's, but if any of you are reading this it sounds like there is a lot of Source Code developed for this already on the Nexus 4. If anyone reading this knows someone capable of doing this if you could forward it to them, because I'm sure I'm not the only person who would like OTG or "USB Host" be available for this phone.
I guess nobody has tried to work this yet? I still haven't seen any kind of development.

Surprising, really. I'm a little butthurt about it. But I'm more than happy to hotwire the 5 volt lead on my OTG cable upto an external power supply for testing if anyone has some mad keyboard skillz and wants to use my phone as a guinnea pig.

usb otg support on LG optimus g 970
I am running an Optimus G 970 and I was attempting to gain support of an external USB DAC called "HiFimediy Sabre".
My first project is to attempt to gain some usb otg functionality.
I created a cable to test since the native 5vdc power out function is not there.
I used my computer to power the cable with 5vdc which was verified by the phone "slow charging".
I ran the "usb host diagnostics". This is a diagnostic tool and it looks at the functionality of the usb port.
Note the following.
1. Phone is rooted.
2. Phone is running all stock software and firmware.
I was asked to reboot to apply a firmware fix by the app after allowing it rooted access.
The app was run one more time following the instructions on the screen and plugging in my pny 16gb usb drive.
It was not able to connect.
I received the following unique code: 188704.
I will follow up when I know more.
