1.cd /etc/udev/rules.d
2.gedit 51-adb.rules (编辑rules文件，文件名随意，如gedit会自动打开一个文本，且将文本命名为51-adb.rules)
3.在51-adb.rules文件里添加设备的PID和VID信息
SUBSYSTEM==“usb”,ATTRS{idVendor}“2xxx”,ATTRS{idProduct}“09xx”,MODE=“0666”,OWNER=“q”
4.保存并关闭51-adb.rules
emulator-5554
netstat -ano | findstr 5554
杀掉进程taskkill /pid 进程号 /f
