adb: device not found

Question

I'm trying to build a Kivy app on my Android phone using Buildozer. But adb is not finding my device. This is the error I am getting:

dan@dan-asus:~/kivy$ adb usb
error: device not found
dan@dan-asus:~/kivy$ adb devices
List of devices attached 

I've added my vendor and product id that I got from lsusb in my /lib/udev/rules.d/70-android-tools-adb.rules file as so:

# Lenovo A789
SUBSYSTEM=="usb", ATTR{idVendor}=="17ef", ATTR{idProduct}=="7497", MODE="0666", OWNER="dan", TAG+="uaccess" 

Have two 1.1 and two 2.0 USB outlets. Tried all four of them. Made sure I restarted adb every time I made a change and even tried to reboot my phone a few time.

What am I missing?

adb version is 1.0.31

I know this should be a comment, but I don't have enough reputation for that... so here is my "answer".

I can think of a couple of things that you don't mention specifically in your question:

1. Do you have a file ~/.android/adb_usb.ini? If yes, is the vendor ID written there? (in your case should be 0x17EF in a single line). Try with that and restart your ADB server.
2. Is ADB enabled in your device? You can check that with lsusb -v -d 17ef:7497 | grep -B 3 -i iInterface and look for some interface with class 255, subclass 66, protocol 1. That's your ADB USB interface in the device, if you don't find it, check the device's settings/configuration.

Hope it helps.
