I am new to android. I have just downloaded and installed android sdk. Now when I run the application from eclipse, my device is not getting detected. I have googled and was brought up with this as my solution, but that also didn't worked.

Here's the 51-android.rules

SUBSYSTEMS=="usb", ATTR{idProduct}=="0bb4",  ATTR{idProduct}=="0c03", MODE="0666", GROUP="plugindev", OWNER="<username>"

After that I rebooted my laptop, and ran this command:

username@laptopname:~/Android/adt-bundle/sdk/platform-tools$ adb devices

The output i get is:

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 
????????????    no permissions
