Here's how I can enable USB debugging on Kindle devices
From Kindle Fire, open Settings.
Depending on your device, do one of the following:
Original Kindle Fire - No action required. ADB is enabled by default.
Kindle Fire HD - Select Security.
HDX and newer models - tap “Device” or “Device Settings”, then press “Serial Number” 7 times until “Developer Settings” is unlocked.
Select "Developer Options." Set "Enable ADB" to "On" and enable USB debugging.
Now you can see your device in the list of devices when you try to start the application. You can go to the same option to disable USB debugging.
I did not have to download any separate drivers for the Kindle Devices, but I always guarantee that my tools and Android SDK platforms are kept up to date.
