Connect ZTE Android Phone to Linux (Fedora) for USB debugging and file transfer

I just got a new ZTE Phone and I'm trying to connect it to my PC via USB. I'm running Fedora 24 and mostly need to connect the phone for USB file transfer as well as app development using Android Studio. There is a connection-mode on the phone that says "Install drivers", which displays the phone as a USB drive with a few .exe files, but they fail to open/run (I guess they are Windows drivers). As a next step I tried to add a udev rule using the idVendor and idProduct that were returned by lsusb (19d2:0241), I set the group to plugdev and the mode to 0664. This still didn't solve the problem (my old phone worked fine after adding an udev rule). adb devices returns a0b14f8b no permissions. I'm a bit puzzled as to where to find the appropriate drivers and make the USB connection work. Any suggestions? ------------------------------- EDIT: the exact model of the Phone is ZTE Axon Elite Gold 5.5inch 32GB
