Answer 1

Maybe its a matter of how you plugged the device onto your computer. I'm using a mac and pluged the usb into one of the keyboard slots. It doesn't find anything even you've installed Kies with all its new drivers. After plugging it directly into one of the slots at the computer the device has been recognized imediately.

Even it is a beginner mistake....maybe it helps :)

Answer 2

In android 4.2.* The “Developer Options” menu item is gone!

Answer: The “Developer Options” menu item on 4.2.* is hidden.

1. Goto Settings -> About Phone.

2. Goto “Build Number” at the end of the Scroll list.

3. Tap on “Build Number” repeatedly (7 times). On your third tap you should see message indicating that you only have 4 more taps to go to ‘become a developer’.

4. Continue: 4 more taps.

5. Hooray, you are now a ‘Developer’, go back to the Setting page.

6. You should see Developer Option menu item in your setting list now.

7. Open Developer Options and check USB debugging > Ok

****it's work for me****

Answer 5

Addition to Tor-Morten's answer: Only checking the Developer setting for USB debugging may not be enough. The USB connection setting (Android 4.4: Settings -> Storage -> Option Menu -> USB computer connection) needs to be checked for either "Media device" or "Camera" before it will be shown in Eclipse's Android Device Chooser window.

Answer 6

In addition to Settings -> Applications -> Development - Enable USB Debugging, click on the following option:

Revoke USB debugging authorization

And then plug the device again.
