error: insufficient permissions for device

参考

shily@hh-desktop:~$cd ~/sdk/android-sdk_eng.sdk_linux-x86/tools
shily@hh-desktop:~/sdk/android-sdk_eng.sdk_linux-x86/tools$ ls -l adb
-rwxr-xr-x 1 shily shily  341694 2010-05-11 05:46 adb
shily@hh-desktop:~/sdk/android-sdk_eng.sdk_linux-x86/tools$ sudo chown root:root adb
[sudo] password for shily:
shily@hh-desktop:~/sdk/android-sdk_eng.sdk_linux-x86/tools$ ls -l adb
-rwxr-xr-x 1 root root   341694 2010-05-11 05:46 adb
shily@hh-desktop:~/sdk/android-sdk_eng.sdk_linux-x86/tools$ sudo chmod u+s adb
shily@hh-desktop:~/sdk/android-sdk_eng.sdk_linux-x86/tools$ ls -l adb
-rwsr-xr-x 1 root root   341694 2010-05-11 05:46 adb
shily@hh-desktop:~/sdk/android-sdk_eng.sdk_linux-x86/tools$ 
这样无论哪个用户启动adb 使用的都是root权限，就不会提示权限不足的错误了。

=========================
在使用的过程中发现adb pull下来的文件属主权限为root:root，所以修改起来不方便。但是我不经常下载文件修改，也就忍了。

接着:

lws@lws:~/worksofts/android-sdk-linux/platform-tools$adb kill-server

lws@lws:~/worksofts/android-sdk-linux/platform-tools$ adb start-server
