"""Driver for FreeStyle Libre 2 devices.

Supported features:
    The same as the fslibre driver.

Expected device path: /dev/hidraw9 or similar HID device. Optional when using
HIDAPI.

This driver is a shim on top of the fslibre driver, forcing encryption to be
enabled for the session.

Further information on the device protocol can be found at
