I bought the Samsung Galaxy S GT-i9000. This is my first Smartphone and ... yeah ... I am developer.

The same evening I tried to connect the phone with my Ubuntu system to write a little App. And, guess right ... it didn't work.

I could not solve the problem even after reading several threads about the same problem and rereading the Google device installation guide.

It was really a pain in the ass, BUT ... finally, I found a simple and funny solution:

./adb start-server

Now, the important step:

Restart the phone while plugged via USB to the OS.

See:

./adb devices

The phone should be in the list of attached devices.

That's it ... no magic :(
