Hi BeMaNe
I'll try to help you on this issue.
Nothing happens on the computer when plugged ? No "plug" sound, no icon ?
Some ideas that crossed my mind :
- Have you tried a shorter cable ? sometimes, long cables can affect the data link.
- Have you tried another USB port ?
- Maybe another computer to test on ?
About the USB setting on the phone, it might be hidden in the "dev menu".
You can find it by following the tutorial on this page :
Turn on USB Mass Storage mode in Android 4.2 or later versions Android 6/7/8
