Do below steps for all "Device Functions" (Android Compost ADB Interface or Kindle) - Select a function - select properties. click on "Change settings" in general tab. - Driver tab-> Uninstall After doing this Windows will start searching for appropriate drivers for the connected device. Wait till it completes. You may even watch the progress and result of drivers installation attempt by clicking on the "new hardware" located in minimized tray area in bottom right of the desktop. If this auto driver installation does not start, you might need to unplug and replug the device after the un-installation completes. See the result to confirm whether Android Compost ADB Interface is installed with the auto detect or not. If it is, then try to run adb command to list the connected device. If "Android Compost ADB Interface" is not installed or adb command does not show the device then you have to try below steps. 1. Go to Control Panel\Hardware and Sound\Devices and Printers 2. Locate the device (should be named as "Kindle") 3. Right click -> properties 4. Hardware Tab 5.

If "Android ADB Interface" is having exclamatory icon associated (or "unknown" is there), select that function and click "Properties" button. 7. "Change Settings" in new window under "General" tab. 8. Driver tab in new window 9. "Update Driver" -> "Browse my computer for driver software" 10. Select "Let me pick a list of device drivers on my computer" 11. There should be a list appeared, select "Kindle" , go next to complete the update. You should be able to get success this time. All the best. Thanks.

Hi Sujoy, thank you for the instructions. But unfortunately, it does not work. After uninstalling the drivers, nothing happens. So, I re-connected the USB cable, Windows automatically installed the driver again. If I choose to scan hardware changes, Windows also installs the driver automatically. I tried several times. The result is identical. Just FYI, on the same PC, I have no issues with S4 or Note 3. Anyway, I will find time to try it on another machine.

Ok. Thank you for writing back. When windows auto-completes the driver installation, Can you try following? 1. Go to Control Panel\Hardware and Sound\Devices and Printers 2. Locate the device (should be named as "Kindle") 3. Right click -> properties 4. Hardware Tab 5. See all the "Device Functions" appears in the list do not have any exclamatory icon associated, mainly "Android ADB Interface" or "unknown". 6. If "Android ADB Interface" is having exclamatory icon associated (or "unknown" is there), select that function and click "Properties" button. 7. "Change Settings" in new window under "General" tab. 8. Driver tab in new window 9. "Update Driver" -> "Browse my computer for driver software" 10. Select "Let me pick a list of device drivers on my computer" 11. There should be a list appeared, select "Kindle" , go next to complete the update. Let me know the result.
