question

Hi Kevin, Thank you for your post. As you mentioned above, adb command doesn't work means please restart your adb by using below commands. adb kill-server adb start-server To connect your Kindle Fire to ADB, you must first enable ADB on your device. 1. On your device, go to Settings.
Note: This does not apply to Kindle Fire (1st Generation), which has ADB enabled by default. 2. Under Security, turn Enable ADB to On, and then click OK in the pop-up warning message.
Note: As a security precaution, we recommend turning Enable ADB to Off when you are not trying to connect to the device with ADB.

I was able to connect my Fire HDX to the 'Android Composite ADB Interface' Google Driver Version 8 based on http://www.jayceooi.com/2011/12/13/how-to-install-kindle-fire-adb-usb-driver/ android_winusb.inf ;Kindle Fire %SingleAdbInterface% = USB_Install, USB\VID_1949&PID_000C %CompositeAdbInterface% = USB_Install, USB\VID_1949&PID_000C&MI_00 adb_usb.ini 0×1949 but >adb devices returns nothing..

forget previous post. from SDK Manager add http://kindle-sdk.s3.amazonaws.com/addon.xml to Tools/User Defined Sites. then under Extras install Kindle Fire USB driver. This will add \extras\amazon\kindle_fire_usb_driver\KindleDrivers.exe Then carefully follow https://developer.amazon.com/sdk/fire/connect-adb.html Message was edited by: pkrusn
