I've done everithing I need to in order to ADB recognize my device
As you can see, it is connected.

But eclipse won't let me work in peace

Additional info:
juan@juan-TE5:~$ lsusb
Bus 002 Device 006: ID 22b8:2d66 Motorola PCS
juan@juan-TE5:~$ cat /etc/udev/rules.d/51-android.rules
UBSYSTEM=="usb", SYSFS{idVendor}=="22b8", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666", GROUP="plugdev"
I have also checked in the device "debuggable mode".
Any ideas?
Updated
Now I see this

回答1:
Sometimes there is another option inside of Dev Options called USB Debuggable. Need to have that on as well...as Isabel suggested.
回答2:
I had a similar issue on Ubuntu 14 with OpenCv 2.4.9, I found a solution.
Check out this link for more info: http://developer.android.com/tools/device.html
Basically, all you should need to do is:
Create this file as sudo
sudo nano /etc/udev/rules.d/51-android.rules
Copy and paste this line, but check and make sure you have the right vendor ID, into the file:
SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"
Finally, use chmod to give permissions:
chmod a+r /etc/udev/rules.d/51-android.rules
You can get the vendorid from the link, it should have all of them. The mode, specifies read/write/etc. and the group defines which Unix group owns the device node.
