Using ADB on Windows 10 -> error: no devices/emulators found

[Matevz Leskovsek]

Hi all, I have android SDK installed, but I guess I only included
Samsung drivers as at that time I was moding samsung phones mainly.
Now when I connect LG Q6 to my windows 10 workstation and run adb
commands I get "error: no devices/emulators found".

Then I installed ADB binaries from here:
https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads/
and getting same error.

Do I need to install LG drivers? Do I need to update SDK? Any other
tips? Can I check my USB cable and connection to the computer with
some simple command?

On my Samsung it was suggested when it went unrecognized to switch from File Transfer to Photo Transfer, then the device was usually recognized and identified with a serial number you can pull with adb devices -l (thats slash lowercase L for "list")
