I recently bought a new phone running on Android 5.0.2 and, after enabling the Developer Mode and activating USB debugging, I was unable to connect it to Eclipse on Windows 10. The DDMS view and adb devices command showed an empty list.
This is how I fixed it:
1) Make sure you the Google USB Driver installed in your Android SDK folder.
2) Connect your device via USB and open Control Panel -> Device Manager.
3) You will see under "Other devices" an unrecognized "ADB Interface". Right-click on it and select "Update Driver Software".
4) Click on "Browse my computer" and enter the path to your Google USB Driver (<sdk>\extras\google\usb_driver\).
5) Click on "Let me pick from a list of device drivers" and select "Android USB Device".
6) Save changes and restart your IDE. Your device should be now visible from your DDMS view.
