I added a serial gadget using ACM function: https://github.com/tejado/android-usb-gadget/commit/7e29b44dd5b9b12b3f84717ee40182d3b853493f

It might require a specific Android ROM which has ACM activated. I will look into other functions which could be an alternative to ACM abd are usually part of Android.

My device is XIAOMI pad 5, and this rom didn't have usb serial driver lib.

1|nabu:/system/lib # modprobe -d /vendor/lib/modules usbserial vendor=0x1a86 product=0x7523
modprobe: alias lines in modules.alias must have 3 entries, not 5
modprobe: alias lines in modules.alias must have 3 entries, not 4
modprobe: alias lines in modules.alias must have 3 entries, not 4
modprobe: alias lines in modules.alias must have 3 entries, not 4
modprobe: LoadWithAliases was unable to load usbserial
modprobe: Failed to load module usbserial: No such file or directory

Can you add gadget serial support like https://android.googlesource.com/kernel/common/+/bcmdhd-3.10/Documentation/usb/gadget_serial.txt

I did - it is in the commit I pointed out before. It is done over gadget CDC ACM (see your link). Can you provide me your Device Info in Android USB Gadget tool app on your device?

Is there an example on how to use this? I simply like to echo all incoming messages from serial onscreen.
