Method 1
Connect devices to computer and execute lsusb
Find current device's info:
Bus 001 Device 006: ID 2717:ff08
2717 is VendorID and ff08 is ProductID
Then create /etc/udev/rules.d/51-android.rules (sudo needed) and add this line:
SUBSYSTEM=="usb", ATTR{idVendor}=="2717", MODE="0666", GROUP="plugdev"
At last execute:
sudo chmod a+r /etc/udev/rules.d/51-android.rules
Another simple approach
Use this one: android-udev-rules
