@ -106,7 +106,7 @@ By default serial debugging is disabled. To turn it on simply change ```ENABLE_U
Currently the following boards are supported by the library:
* All official Arduino AVR boards (Uno, Duemilanove, Mega, Mega 2560, Mega ADK, Leonardo etc.)
* Arduino Due, Intel Galileo, Intel Galileo 2, and Intel Edison
* Arduino Due, Arduino Zero, Intel Galileo, Intel Galileo 2, and Intel Edison
* Note that the Intel Galileo uses pin 2 and 3 as INT and SS pin respectively by default, so some modifications to the shield are needed. See the "Interface modifications" section in the [hardware manual](https://www.circuitsathome.com/usb-host-shield-hardware-manual) for more information.
* Note native USB host is not supported on any of these platforms. You will have to use the shield for now.
* Teensy (Teensy++ 1.0, Teensy 2.0, Teensy++ 2.0, Teensy 3.x, and Teensy LC)
