Yea, touch panel has STM MCU. When I disconnect touch pannel the output is
root@Khadas:~# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 1a40:0801 Terminus Technology Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
But I can’t see nothing new in /dev/ when I connect it/
so that means it is recognized
try this and see if it works, don’t worry about config file, just execute this and see if it works

Touch should work on this window, right?
Yep, but you cannot enter characters
yup it should work here
This module is not present, you might need to modify the image and rebuild the kernel using fenix
Can you please make a short instruction of how to do that? I’m newbee in Linux images
did you try the one I told before?,
Tried this, Doesn’t help 
if it didn’t work then you definitely need a modified image,
I can instruct you but there are some requirements that you need to have,
do you have a Linux computer or at least a decent spec computer that you can run a virtual machine on ?
Yes, I Have VM with Ubuntu 18.04
great !, follow the given instructions and do as it says,
So which module I need to enable and how to enable it? 
Great Thanks for help
I am building an image for you… I will update at EOD the link to download
Thanks a lot! But it would be nice if you can make a guide for me that I could learn and be able to build it by myself in future
