 Firmware updates require installing a driver.
 
-- Windows: The newest versions of Windows should automatically install the required USB drivers. Alternatively, you can download the latest drivers from the [FTDI VCP website](https://www.ftdichip.com/Drivers/VCP.htm).
-- Linux: The latest `libftdi` is provided in the Flatpak.  If installing via PyPI instead, you will need to install `libftdi` yourself.  On Ubuntu and derivitaves, this can be installed with `sudo apt install libftdi1`.  The package name may be similar on other distributions.
-- macOS: (TODO: figure out; ~~`brew install libftdi` doesn't seem to make the error go away.~~ UPDATE: https://github.com/lsgunth/pyft232/pull/22 is merged but not yet published, in the mean time we should manually apply the change in our releases that have the library bundled.  Also, should we bundle `libftdi1.dylib` and its dependencies, or request users install it via Homebrew themselves?)
