Keyboard initialization process takes a few seconds at start up. During that you will hear buzzer from the keyboard. You need to plug USB cable after hooking up your keyboard to the converter.

In case of using ATMega32U4(Teensy2.0):
Just run make

$ make
To select keymap:
$ make KEYMAP=[plain|...]
Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named keymap_<name>.c
and see keymap document(you can find in top README.md) and existent keymap files.
