+Teensy 2.0 and USB
+------------------
+
+If you want to implement USB functionality using Teensy 2.0, you need to
+add special macros/define using :ref:`projectconf_build_flags`:
+
+* ``-D USB_HID``
+* ``-D USB_SERIAL_HID``
+* ``-D USB_DISK``
+* ``-D USB_DISK_SDFLASH``
+* ``-D USB_MIDI``
+* ``-D USB_RAWHID``
+* ``-D USB_FLIGHTSIM``
+* ``-D USB_DISABLED``
+
+Example:
+
+.. code-block:: ini
+
+    [env:teensy_hid_device]
+    platform = teensy
+    framework = arduino
+    board = teensy20
+    build_flags = -D USB_RAWHID
+
+See `Teensy USB Examples <https://www.pjrc.com/teensy/usb_debug_only.html>`_.
