I am not sure that I understand your question.

In brltty-5.2 this is done installing the file
40-usb-brltty.rules in /lib/udev, or do I miss something?

I see in this file:

# Device: 1C71:C005
# HumanWare [all models]
ENV{PRODUCT}=="1c71/c005/*", ENV{BRLTTY_BRAILLE_DRIVER}="hw",
GOTO="brltty_usb_run"

Do you mean that a device is missing?
