MECOOL + LE Kodi not recognizing USB

Very new to this type of setup and wondering if I've done something wrong.

Have MECOOL M8S Pro+ box and have managed to setup LE and Kodi and when I turn it on it boots into LE Kodi.

Then following the Kodi Wiki I have tried to add videos.

This is where it all comes to a stop. Kodi recognizes the USB drive and lists it by it's name.

Then I hit add videos and browse the USB drive does not appear anywhere.

I have tried 2 different USB drives with the same result.

Does anyone have any suggestions as to how I can fix this problem ?

OK after much frustration and deep thought I finally solved the problem of the missing USB Drive

Add Videos --> Browse Source --> Root --> /storage -- /media and there's your USB Drive.

You can then add folders as per normal.
