Why ADB Ubuntu does not recognize my device?

I bought a Motorola G, and I try to install my programs from DEVELOPED ADT Ubuntu, the problem is that I get the message when I ejercutar application

enter image description here

From terminal, the following is displayed

zhelon@zhelon-Lenovo-IdeaPad-Z400:~$ sudo adb devices
List of devices attached
???????????? no permissions


The most pragmatic way to fix this would be to run adb tools with root access. You are getting a no permissions error, because you need super user privileges to interact with attached devices.

To improve the answer, and alleviate superfluous security concerns, you can also run adb without root by adding a udev rule for your device. Instructions here.

First, query lsusb:

$ lsusb
Bus 002 Device 103: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II]

Then create a new rules file and add the rule to it (/lib/udev/rules.d/10-adb.rules):

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}=="6860", MODE="0600", OWNER="username"

Then restart udev, or reboot your computer (recommended).
