adb doesn't see android device ubuntu

Question

Ubuntu 14.04 My device is lg l90 d405

lsusb output:

Bus 003 Device 004: ID 1004:633e LG Electronics, Inc. 

Developer options is checked. I edited rule file:

SUBSYSTEM=="usb", ATTR{idVendor}=="1004", ATTR{idProduct}=="633e", MODE="0666", GROUP="plugdev" 

How can I fix it?

在“ USB PC连接”中将USB选项更改为“发送图像（PTP）”。
