Android kernel OTG host drivers - what devices are supported? - Android Q&A, Help & Troubleshooting

I'm currently trying to determine what devices are supported natively in the Android kernel for USB OTG.
For instance, on most newer Linux distros, Mediatek USB VCOM drivers are supported out of the box, whereas on PC they are not. I was hoping since Android is based on a Linux kernel, I could count on these Mediatek drivers being included in the Android kernel as well.
However, I can't find any documentation on supported device drivers for Android USB OTG.
Any info or guidance would be greatly appreciated.

[Q] ADB Communication with Android Table VIT T1310

Hello colleagues.
I bought a few days ago in Venezuela, a tablet with Android, vit t1310 model. I want to develop directly into it as I did the same for other Android devices, communicating via USB cable and adb. So far I can not find drivers for the tablet, and adb is not recognized as a device.
Any idea where I can find or someone that has the drivers to use the adb and these tablets?
Thank you.
Go to device manager
update driver manually
let me pick from a list of drivers
choose adb
I may work

[Q] Is is possible to add USB HOST drivers?

Hello,
I would like to know if it is possible to add/install USB HOST drivers to my phone. According to manufacturer specifications, in the "list of available features" I see "android.hardware.usb.accessory" but not "android.hardware.usb.host".
From what I learned, the difference between the two is in USB host the phone powers the bus, and in accessory, it does not.
I need this to be able to attach a hardware keyboard, and they are rarely self-powered.
My phone is a Sharp SH-01D, running 4.0.4, not rooted.
And, follow-up questions:
1. If possible, do I need root? (I am guessing yes, unless there's some installable driver, like in PCs).
2. Where do I get this driver from? Almost all newer models support this functionality (my girlfriend has the SH-10D, now upgraded to 4.1.2 but according to specifications, it had USB host even before the upgrade), so can I get it from her phone? Or is the driver processor-specific -- mine has a TI OMAP 4430, and hers has a Snapdragon MSM8960.

[Q] Help Understanding/Loading/Developing Kernel Modules

The Story started when i wanted to install Drivers for USB OTG on my Droid, And now im ended up by a black hole, im completely lost
What i've Researched/Understand:
1.Kernel is a Bridge between Software and Hardware
2.Drivers must be included in Kernel
3.To Load Drivers, We Need to Extends The Functionality of the Kernel using Some *KO Files Through some Command-Line Commands
What i Have:
1.Source Code for my Phone Kernel
2.Driver for the Device that will be connected Over USB OTG
3.A Rooted Phone
4."Tenda W541U" Is the Device will be connected Through USB OTG and it's chipset is "RT2070L"
What I'm not understanding/Asking for:
1.How can i make these *KO Files?
2.Do i need to make them from Scratch?
3.How to Load them?
4.Will this modify My Kernel Permanently?
5.Do i need Unlocked bootloader?

My device supports OTG but OS doesn't

Hello,
I was trying to develop an app that uses USB Host/Accessory mode to communicate with a python script on another linux device (for now it's my PC). I noticed that getAccessoryList() and getDeviceList() both return null/empty and after searching a lot I came across USB Host Diagnostics from chainfire.
And when I tried it this was the result: usbhost(dot)chainfire(dot)eu/?search=1382824
As you can see, the kernel supports OTG while the OS doesn't. My devices are Samsung S5 and Note 8.0 and both gave the same exact results. My devices are rooted but that was the only modification i've done to them.
So is there a way to fix this issue ?
Thanks in advance.

Install ethernet driver?

Hello!
I want to connect my SGS-II i9100 via ethernet!
I have a OTG USB cable and a USB ethernet adapter ASIX AX88179.
On my Galaxy-Tab-S2 (original Rom) ist works out of the box, but not on the i9100.
On the i9100 I've installed LineageOS 14.1, Kernel: DorimanX V13.0b005 and TWRP 3.1.0-0.
I've found this older thread about ethernet driver on an Eee-Pad, the driver package should include the right driver for me:
https://forum.xda-developers.com/showthread.php?t=2039886
I tried it out but on Termux I got the following error-message:
insmod: can't insert '/system/lib/modules/usb_ethernet/asix.ko': invalid module format
what does this mean?
I'm not familiar with linux... unfortunately.
Is there a way to install this driver in such a way or is kernel compiling the only way to integrate drivers?
I've found the original driver: http://www.asix.com.tw/FrootAttach/driver/AX88179_178A_LINUX_DRIVER_v1.19.0_SOURCE.tar.bz2
Can anyone please help me?
thanks and best regards!!
