# The hidraw support doesn't catch Xbox, PS4 and Nintendo controllers,
# so we'll just use libusb when it's available. Except that libusb
# requires root permissions to open devices, so that's not generally
# useful, and we'll disable this by default on Unix. Windows and macOS
# can use it without root access, though, so enable by default there.
