To Enable USB Debugging, Enable it in the Android device by Applications–>Development–>Enable USB Debugging.
Then you need to add the following file (rule) to the udev rules directory :
su -
vi /etc/udev/rules.d/99-android.rules
Add the following code to this file :
SUBSYSTEM==”usb”,SYSFS{idVendor}==”04e8″,SYMLINK+=”android_adb”,MODE=”0666″
Here idVendor means your device vendor, so change it accordingly. For more details, refer this
http://developer.android.com/guide/developing/device.html
After saving this file, run this command to reload the udev rules.
udevcontrol reload_rules
After that, Everything will work!…
