"USB Debugging" mode not visible, Samsung Galaxy Note II
Apologise for my ignorance as I dont have a Galaxy Note II but since you have the SAMSUNG Android ADB Interface I am presuming when you run command (and get this from google too)

adb.exe devices


Do you at least see a Serial Number?? 

I had a similar issue with my Nexus 5 and noticed I too have the same drivers however for my computer to connect to the device I had to make sure my device is:


NOT in a Locked State (meaning the phone is not on the lock screen)
Debugging is enabled (You already have)
And accept the adb connection physically on the phone (just do the adb connection and it'll prompt your device for privileges.)
