Windows 8.1 drivers for low end device
I was able to use a Samsung driver.


Go to Device Manager, find the Android device, and select Update Driver Software.
Select Browse my computer for driver software
Select Let me pick from a list of device drivers on my computer
Select ADB Interface from the list
Select SAMSUNG Android ADB Interface (this is a signed driver). If you get a warning, select Yes to continue.
Done!


For good measure, I ran adb kill-server and adb start-server. Then when I ran adb devices I finally saw a device listed so I fired up IntelliJ and all is good in the world again!
