Android ADB error: "device not found" on Ubuntu

Http://www.pocketmagic.net /? P = 762 Android ADB error: "device not found" on specified tuby Radu motisan posted on June 2nd, 2009

I 've been getting this error way too often recently, so I 've decided to point out some of the causes.

1) using my older desktop pc I cannot use ADB to connect to the Android device, but I can see the files on the micro sdcard. seems to be related to hardware, and not much I cocould do to fix it. on the other hand, I can use my notebook to connect with ADB wihtout any issues.

2) under Ubuntu, using latest SDK from Google, I remember everything worked smooth: ADB shell, ADB push, and the others. suddently, I got this error:
* Daemon not running. Starting it now *
* Daemon started successfully *
Error: device not found

Same for ADB devices, ADB-getstate and so on.

The problem is that we need to run everything with root privileges.
So the correct way to do it is:

Sudo./ADB kill-Server
Sudo./ADB Shell

Hope this saves you some precious time.
