USB otg.

Otg is the capability to run a mouse, USB and sometimes a hard drive via a micro OTG cable ... are there any roms that has that capability pre installed.??

8013 PROBLEM with OTG usb on Jelly Bean

Many of us with JB and 8013's are not able to us OTG devices on our Notes. I tested it yesterday with three different ROMS and none of them supported it. While on 4.0.4(ICS) everything was fine, not one issue. Are there any Devs that could help with this as I am not knowledgeable enough to do it. Thanks a lot!

Yes please, if one understand the working of the otg usb please help us.

Also Tried ROMN8000 DR AKRIM ROM N8000XXBLJ9 v06 27112012 Jelly Bean NO GO HERE EITHER
I also tried a stock JB update from Germany, NO GO EITHER.
so for me anything JB related stops OTG from working.

Well, I know you guys want OTG. I was just asking in general. I just wanted a stock JB Rom that is compatible with 8013. I won't be using OTG. Hmmmm stock JB update from Germany....i should try that.

i have an otg cable on the way, so I'll experiment when it arrives.

What are the advantages of using a OTG instead of the micro USB? So you can attach like flash thumb drives?

Otg gives you a supported usb drive.
So you can attach usb keyboard, usb mouse and a flash drive.

or a game pad.

or a umts modem... which is the problem:
I did look at the dmesg output, when I was under ICS mostly because of the current consumption, but also looking for the IR port.
I see now a big difference there, using the German JB 8000 Rom with the 8010 files.
Somewhat (perhaps a Init script) does load the OTG usb kernel modules, then load a usb modem (mif related to umts) and after a while there is a termination of a certain unknown pid, probably because of the modem not responding, which is then unloaded and also does switch off that OTG usb port and unload it's k. modules. Seconds later the whole thing is repeated again and again...
Surely also a reason why it's consuming more power, and probably the reason why other OTG devices have troubles.
I would like to help, but I don't know how android works on that (kernel) level, I had some knowledge about usb on linux 5 years ago, so I don't know how it has evolved.
If someone of you, Dear Rom Backers, could lead me to some (hardcore) knowledge about the whole startup(/wake) process.
I could investigate a bit more.
Other problem I did encounter with JB, somewhere a memory leak, my RAM slowly does fill up in a way, where I can't reset it, without rebooting.

OK I have my otg cable now, and can see the problem, but not the cause.
When I get near to something that can adb in I'll have a look, if anyones' got any pastebins of dmesg and logcat in the meantime please let me know.

this is using the 8000 rom on 8013 and 8010 devices, no idea if the issue is on 8000 devices, or whether it will be there on the 8010/13 firmware.

maybe it's conflict because people are flashing firmware that is not supported on their tablet, i sure hope that is the case.

Absolutely. I have an N8000 using the correct official N8000 JB firmware for the device and USB works perfectly. That's why there are different firmware versions for different devices - simple.
I have a small unpowered USB hub attached to a cheap generic USB OTG connector. I am typing this using a USB wireless keyboard and mouse and I have a Note 10.1 with 160GB of storage. 32Gb internal - 64gb using internal micro-SDXC card and 64gb with a second micro-SDXC in a micro reader attached to the hub (seen as a usb drive 1 so presumably can add more). That's 160gb seamlessly available in all programs for Video, Music, documents and whatever. Eat you heart out fruit-boys!!

For those running one of the N8000 roms on your N8010, try this:

Kernel has insecure boot.

Thanks to alirey for uploading the original OTA update zip

Thanks to dsixda kitchen for insecure boot added to kernel.
May also work on 8013 as well.

Is it fixed in 8010 wifi release.

[Q] Is there a way to allow tab 2 7 to read storage > 4GB via usb otg

My tab (GT 3100 running stock 4.1.2 on stock kernel) won't let me mount storage higher than 4 GB via usb otg.
Is there any way to enable it?

I have the same problem. Have been trying to connect several flash discs to my GT-P3100 (RIPPER ROM V3, 4.1.2) with the OTG USB cable.
Mostly the tablet did not react. After getting the same error as shown in your screenshot I had to disconnect the OTG cable from tablet(not only the flash disc) From 5 different ones only one worked (8GB FAT32), but not all time. The others are different capacity, but also FAT32.
Is there any problem in the Android 4.1.2 on this tablet regarding OTG?

Usb power hub and WD HD...

Hey guys..
I have a WD 1tb HD which iz self powered...
I want to use it with my tab 2 p3100
I understand that tab cannot supply enough power to the self powered HD..
I have made a Y-cable for the purpose...
The HD lights up and vibrates indicating that its receiving power but unfortunately it doesn't show up on the tab..
Then I felt the cable might be the reason and I brought a usb power hub...
Its exactly the same situation with the usb power hub as well..
Plze help me out with getting my HD work with the tablet...
I have searched a lot but couldn't get a proper way to get things going...
My tab iz rooted with sungsonic hd v2 running...
USB power hub iz iball lappie...
WD HD uses usb 3 but tab doesn't recognize it with usb 2 cable as well..
Share it if u know it...

You need whether the official Samsung OTG Dongle (expensive) or a OTG Cable you can find almost every where for some buks (Amazon, eBay, ...).
The standard charging Samsung cable is not compatible !
You also need the Y cable if you use a high power/capacity devices you can plug on any USB port such as a Laptop or on the main power supplier if you use a power USB hub that allow it.
Then you need an application that support Fatx, NTFS, and/or HFS such as the Paragon apps (free of charge).
Support for EXT3/EXT4 is another matter as I couldn't find a working one when I was using ICS 4.0.4, but I didn't retried since I'm using Jelly Bean. Maybe there are working now ??? ^^
You can use the same OTG cable to plug any USB keyboard/mouse or any other USB devices if the ROM do support them, or if you use a custom ROM that do support them...

Not necessarily.....
Needed hardware and drivers may be different or lacking.
USB support is defined within the kernel drivers. Native support may be different between Android devices and firmware.
For example, the P6800 4.1.2 JB supports USB for iPhone_4S, P6810 ICS does not. (Only up to iPhone_4)
Sent from my GT-I9500 using xda premium

As I said, it's just an example of USB support from kernel. Although similar, some kernels have various functions enabled, some don't.
Sometimes, changes (for support) need to be hard coded/added at the kernel source or just from config file before compile. This applies also to USB and OTG -A & -B devices.
OT, have enabled USB support for missing iPad & iPhone 5 in upcoming SkyHigh kernel 3.0.0 (untested)

Sorry, I think you missing my point/example.
I am talking about unsupported USB/OTG features and support for various peripherals. Not all are supported with stock kernel.
As a very basic example, take a look at any kernel .config file.

USB On-The-Go

So I'm veery close buying this wonderful moto g device, but storage is my biggest concern. Luckly I have seen that usb otg is supported at moto g, but some sites (including GSM arena) say it has only USB host(?) support. Does moto g have fully working usb otg? I mean that there is possibility to transfer files between phone and memorystick and so on. Because of the lack of SDcard slot, usb otg is very important feature for me. I just want to make this thing clear before I order the device from amazon. Thank you, answer would be highly appreciated!

Yes, you can transfer to and from usb memory stick. USB on the go works fine on Moto G
