Debug mode on the android device under the operating system Ubuntu 11.10

For debugging my android applications, I bought a Sony Ericsson Xperia Neo V.
When I used the command:

adb devices

 
from the directory ~/android-sdk-linux/platform-tools/ 
I received the following:

List of devices attached
???????????? no permissions

I did as written http://developer.android.com/guide/developing/device.html, 
but after adding the id to the manufacturer must restart the service by typing:

sudo service udev restart

Then I did the following steps:

1. close eclipse
2. go to platform-tools directory
3. do: sudo ./adb kill-server 
4. disable the development debugging on my phone
5. enable it again
6. do: sudo ./adb start-server
7. do: ./adb devices

I received the following:

List of devices attached

Hope it is helping!
