 To be able to setup a complete development environment, you'll need to manually
 install some system libraries (including the development version of your
 distribution corresponding packages):
-- Treal support: `libusb` (1.0) and `libudev` are needed by
-  the [`hidapi` package](https://pypi.org/project/hidapi/).
 - log / notifications support: `libdbus` is needed.
 
 For the rest of the steps, follow the [developer guide](../doc/developer_guide.md).
