Sorry for the mess. Its late, and I wanted to type this up so I could crash...
To get adb going you must download the android sdk (google it).
*Run SDKManager.exe and download the google-usb_drivers package from "3rd party tools"
* Download platform-tools as well
Open a command prompt and run adb update usb to get the .android folder to appear.
goto: %USERPROFILE%\.android and edit the adb_usb.ini and add this to the end of the file and save:
;Kindle Fire %SingleAdbInterface% = USB_Install, USB\VID_1949&PID_0006 %CompositeAdbInterface% = USB_Install, USB\VID_1949&PID_0006&MI_01
If you have already plugged your kindle into the usb you may have to open device manager and find "Kindle" under other devices and choose the android_winusb.inf file.
Turn on Installation of apps from unknown sources: tap the top bar>choose more...(+)>device
open a command prompt and run adb kill-server then try adb devices..
you should see a device listed.
