[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] CivZ-FLEX-BEAM-REV2.2 on Note N5110 with screen mirroring

Hello out there,
i have a quick question (at least i hope it's a quick question )
I bought the Samsung Allshare dongle to mirror my Note 8.0 screen to TV.
But everytime i try to mirror my screen it says it cannot be connected because of a hardware issue.
Now i read somewhere that it has to do with the fact that i am running a custom rooted rom. Does someone has any hints for me to get this work on my Note 8.0 with this custom rom?
Thank you very much!

No suitable solution found
After i gave up here my final solution for me:
- i used triangle away
- flashed stock rom (German 4.1.2)
- flashed unsecure boot image
- rooted
- flashed stock boot image
now i have root privileges and my device status is official
With this steps screen mirroring is working
I hope this is a help for those who want to try it

[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..

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] uvc driver on T705 using dashcam and UsbWebカメラ

Hi Guys,
I'm trying to get my new usb microscope working on may Tab S 8.4 4.4.2. stock with root.
Cam is DigiMicro 2.0 Scale (dnt.de)
I only get UsbWebカメラ working but just up to 800x600 Resolution. 720p is max available but doens't work. The Scope supports up to 1600x1280 (2MP).
Also, there are two devices shown in list, just the second one works.
This App worked also before rooting the device.
Dashcam never worked .. asked for access to device but shows nothing.
Same on my Note II with Phoenix Rom v18.8 Android 4.4.2
I read about the uvc driver that is necessary to get usb webcam working over USB-TG.
So when UsbWebカメラ works (limited but works), uvc driver should be on my devices and access possible because of root. Am i right?
But why limited and why doesn't Dashcam work?
Hoping you guys can help me with any tips to get the scope proper working, that would be really awesome!
Cheers!

My guess is that kernel needs a recompile with UVC driver enabled.
I have asked in the Skyhigh Kernel thread to incorporate it:

Opel Intellilink and Android Custom ROM's (OmniROM...) - Compability issues?

Hello, i havent found a similiar thread so...
We bought an Opel Adam Rocks (2014) in which there is the really nice Intellilink System. Its said it will connect with all newer Android phones that installed Android Auto, but when i plug it via USB (tried different cables already) it says "Unknown/unsupported device detected".
My phone: Oppo Find 7 is ROOTED, on latest OmniROM which is of course Android 6.XXX + Android Auto App
My question: is it GENERALLY impossible to connect rooted/Custom ROM phones to it? is there anyone that was successful?
Its not a disaster since we didn't see it as important but it surely would be nice!
Thanks.

I have similar problem at the moment with Huawei Mate 9 and intellilink R4.0 (both new). I am waiting for new firmware and will contact Opel dealer for update.
I have read different forums that different firmware on phone acts different as well as software on head unit sometimes makes problems.
Generally I have read that also some custom roms work and some don´t.
Also there have been several updates for the intellilink systems since 2014. This will cost some € at Opel Dealer. It is not for sure this helps! Maybe it is waste of money.
In this case it is google bringing the disaster... The app brings no information what is going wrong...

i'm thinking about an update for the Intellilink, indeed... and... at least its good to hear that custom ROMs CAN work, so there is still chance. thanks for the info!
