Insufficient permission when running 'adb shell'

Question

I am on Ubuntu 12.04. And I need to use 'adb shell' to connect to my device on linux:

I get Insufficient permission when running 'adb shell'as myself. But when I run it as 'root', it works.

How can I fix 'adb shell' so that I don' need to run it as root everytime?

Answer 1

I guess, the problem and solution are the same as in question "adb devices command not working".

In short: you must inform Ubuntu that android device, connected to USB can be used by unprivileged users (that's forbidden by default).

That's even decribed in official Android Developer's Guide: Configuring USB Access, but I prefer a bit simplier 51-android.rules file.
