OTG functions

Hi, I have an adapter USB to micro USB to try out the OTG of the Samsung. It recognizes a flash drive just fine, but it doesnt work with a mouse or keyboard. My android version is 4.0.3 and the kernel version is 3.0.5.15 (if it helps) Im also using Genius hardware. Do i have to buy an especific brand? what do I have to do to get it to function well?? And one more thing, can I connect a webcam and make t work? (for final universiti project purposes)
Tranks in advance

[Q] Infamous Tab3 Support OTG?

Does the Infamous Tab3 ROM by Jamison904 support OTG? To me, this is the biggest shortcoming of the stock ROM by Samsung, and would be great to correct.
Jamison904: WOW!, this ROM looks GREAT!
Thanks MUCH!

Isnt OTG implemented in the kernel ?
So it is not a question of the rom....

There was one claim that it worked for him/her. We are still waiting for his screenshot or evidence. To me it is not software/ROM/kernel but the HARDWARE does not support OTG usb.

kernal
Try some of the kernels, now the version2 of the 1.6 is tested..

OTG Hardware or Kernal?

I am too new to this to know which is more likely, but I can add some data about my Tab3 7.0(SM-T210R) on v4.1.2m (kernal July 18 2013) :
- I am using an OTG adapter and setup that has worked with other Android phones and it does not work with the stock ROM/kernal.
- The stock ROM/kernal does have some support for the file system, as the /mnt and /storage directories both show "UsbDrive A" ... up to F are in the filesystem.
- There is no indication in the Setting Storage menu for the USB drives. I have seen these USB drives on a TAB3 8 and 10 inche models.
I doubt it is due to hardware, as why would Samsung order different parts for one model than another?
I suspect it is disabled so people have to buy up to the 8 inch, but I LIKE the size of the 7 inch.
I also think it might have been stripped out of the RON/kernal so to save space, as the 7 inch is only 8 GB.
Hopefully Jamison904 or someone who has loaded the InFamious ROM can let us know if it works on the 7 inch.
Anyone tried it?

@rfmic
In Infamous Tab 1.1, the kernel is stock and USB OTG does not work yet.
ketut.kumajaya was working on it in his custom kernel http://forum.xda-developers.com/showthread.php?t=2439564
Someone posted a picture of the controller built in the tab and it should work with USB OTG, its just not implemented in the software.

[Q] Samsung Galaxy Tab Lite 3 7.0 (SM-T110) Usb Keyboard Problem

Dear XDA,
I bought a Samsung Galaxy Tab Lite 3 7.0 (SM-T110) and a usb keyboard that has a male micro usb connector. My problem is that I can't get the keyboard to work. I rooted my tablet, tried custom ROMs and Blackhawk custom kernel, tried adding android.hardware.usb.host.xml file to /system/etc/permissions, but I simply won't work.
I also own a Samsung Galaxy S5 and when I connect the keyboard it works flawlessly. So, the problem is definitely with the tablet. I ran USB Host diagnosis and got the following results:
ANDROID API
Claims support: yes
Classes found: yes
Device detected: no
ROOTED API
Claims support: N/A
Device detected: N/A
KERNEL
Claims support: no
Device detected: N/A
VERDICT
OS support: no
3rd party apps: no
At the moment, I have a stock firmware for south east Europe.
So, to sum up, I tried literally everything I could find, so please tell me if there's a way to get my keyboard finally work.
Thanks in advance!

This won't work over USB since there is no USB-OTG functionality on the Tab 3 Series..

Correction. gt-p52XX otg capable
sm-t2XX [?] not otg.

Thank you for your answers, guys.
Is there any workaround to make it work? Is it possible to make any kernel modifications to enable USB host functionality?

[Q] Using OTG on Samsung Galaxy grand duos gt-i9082.

guys do any 1 have any idea how i can use usb otg on galaxy grand duos.
i m using cm12 lollipop rom.
should i use frost kernel for it

no bro usb is not yet supported in grand
hit thanx button please

No Hardware support for OTG
Even I too was working on that, and found the same thing... The Kernel does not have USB Mass Storage support it seems... That is the Software part. But in the Hardware part, they say that there is no Power supply to the USB Bus which is required...
(Which means no hope for OTG on i9082)

Not working wifi adapters (Zf2 Kali Nethunter)

As the title says, this will be a thread for zf 2 users who installed nethunter and find their external wifi adapters not working for various unknown reasons. I hope that the developers of nethunter for zf 2 see this and atleast help us in finding for solution. (Sorry if my English is bad.)
For me:
Adapter : Tenda w311u+ (rt2870/rt3070)
Kernel : FlareX 1.0 (stock)

guys post about your adapter here, and I will try my best to get them in

adapter: no idea (rt73usb)
kernel: FlareM v1.2
firmware: rt73.bin (for the adapter)

With pcap you can use rtl8187 adapters.
But I have rt3070 and don't know how to compile drivers.

I've been searching some probable solution regarding this topic. Though it includes editing of the kernel and adding features to it via cleaning makefile and the defconfig sh!t (which is I don't effin know where it's located to my phone or should I make one?) like here in this link : https://github.com/offensive-security/kali-nethunter/wiki/Modifying-the-Kernel
Is it correct? If it is, it only shows me " *** No rule to make target 'clean'. Stop. "
If not, what are the other ways to install the drivers to our phone so that we can do it ourselves and make it easy for you?

well, use my kernel directly the command will be ./buildzf2 <v.no> NH
to add something in config kali_zenfone_defconfig
and no worries, I am back to work.

It turns out most wifi drivers are already included (at least in V2.0) but usb otg doesn't work too well on the zenfone.
It doesn't detect my wifi chip when connecting it directly to the otg cable.
However if I plug the wifi chip into a usb hub with its own power source and connect that to the otg cable, it works.
The same wifi chip works well on a galaxy s2.

Still nothing happens ? I'm just gonna wait for you to fix it and post an update ?

Okay I found a few things out that might be helpful:
The usb otg functionality doesn't work on high speed usb devices.
It doesn't even detect any high speed usb devices.
It does detect detect those device sometimes when the battery is at 100%.
Even then, any kind of data transfer kills the connection.
This is when not using an external power source
When using an external power source (like a usb y cable or a usb hub) , everything works fine.
Hence I think that our phones can't output enough power to keep the usb device running.
I found some files (most importantly dwc3-intel-mrfl.c) under kernelsource/drivers/usb/dwc3/ that control the power draw from usb otg devices.
Maybe some changes there might get usb wifi working again?
