I've have a Oneplus 3 running on android 7.1.1. (Rooted) Original Rom. Now when I connect my device to Calibre the device is recognized but there is no access to the sdcard > Books and the "Jobs" keeps attempting to get access to read the Main memory for the books. Tried several things like adjusting the Device Interface Plugin with /sdcard/Books but no joy. Now I cannot find a solution myself so I turn to you guys.
Any solution out there????
thanks in advance,
Fred
