For iOS10 it only show the "Apps" folder.
If you don't even have that, please do:
idevicepair unpair
idevicepair pair
Do the last one multiple times until successful (follow the hints on screen)
Finally reboot your computer.
Now, you will not have access to your media still. It must be a simple bug because it can be solved with:
mkdir ~/Desktop/iOSmount
ifuse ~/Desktop/iOSmount
Note that you will need root permissions to unmount this:
sudo umount ~/Desktop/iOSmount
