# This script depends on PyUSB and tqdm.
# Optionally, comtypes may also be installed under Windows to provide taskbar progress functionality.
# Use `pip -r requirements.txt` under Linux or MacOS to install these dependencies.
# Windows users may just double-click `windows_install_deps.py` to achieve the same result.
# libusb needs to be installed as well. PyUSB uses it as its USB backend. Otherwise, a NoBackend exception will be raised while calling PyUSB functions.
# Under Windows, the recommended way to do this is by installing the libusb driver with Zadig (https://zadig.akeo.ie). This is a common step in Switch modding guides.
# Under MacOS, use `brew install libusb` to install libusb via Homebrew.
# Under Linux, you should be good to go from the start. If not, just use the package manager from your distro to install libusb.
