sudo vi /etc/udev/rules.d/51-android-adb.rules

然后 chmod a+rx /etc/udev/rules.d/51-android-adb.rules
再然后 sudo cp /etc/udev/rules.d/51-android-adb.rules /lib/udev/rules.d/

$sudo gedit /lib/udev/rules.d/50-udev-default.rules

修改 SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664"

$sudo service udev restart
或 $sudo /etc/init.d/udev restart

拔掉usb重新连上再执行：

$adb devices
